1. Introduction

1.1. About this Product Specification Manual

This Product Specification Manual is applicable for AIT-1 Turbo drive. This manual provides information about the Sony SDX-460V series Advanced Intelligent Tape Drives which is

necessary to integrate the drives into OEM products. This manual describes the specifications, ATA/ATAPI Interface, diagnostics, operation and installation of the Sony SDX-460V Drives.

The Sony SDX-460V drive uses data compression to achieve high capacity and high transfer rates. Actual capacity and transfer rate depends on the source file type. The capacity ratings listed in the next subsection are based on a 186 meter tape AIT-1 Turbo cassette. The Sony SDX-460V drive is a high capacity data storage device using Advanced intelligent tape (AIT) technology. The Sony SDX-460V drive achieves high data integrity through read-after-write, an additional level of Error Correction Code, and other features.

The Sony SDX-460V drives provide MIC technology that automatically enhance reliability and performance. The Sony SDX-460V drives provide read and write capability for MIC user data area.

1.2. Introducing the Sony AIT Technology

While magnetic storage technologies continue to push the envelope of recording density and provide higher capacities and transfer rates every 18 to 24 months, improvements in time to access this data have become very limited. Since 1990, tape recording densities have increased up to ten fold, while the time to access this data has increased less than two fold, creating a large mismatch between the amount of stored data and the ability to access it.

This large “gap” between data access latency and areal density has created a dilemma in application development and limited the potential to implement truly cost-effective tertiary storage solutions. Many applications compensated for this deficiency by incorporating multiple redundant tape drives, at higher cost, to achieve an acceptable level of service for their users. Sony’s new Advanced Intelligent Tape design has recognized this need and provided an innovative approach to solving the data latency problem while increasing capacity and data transfer rates.

Traditional, older tape technologies relied mostly on conventional mechanical means, such as faster search speeds or an on-tape index to improve access to stored data. While improvements in electronics and magnetics have been the main enablers of increased capacity and transfer rates, rarely have these same technologies been employed to significantly improve access to data.

Sony’s Advanced Intelligent Tape (AIT) architecture has deviated from conventional designs and employed electronic enhancements to significantly improve access to stored data, using a captive, non-volatile memory chip contained within the magnetic data cartridge. Known as Memory-In-Cassette, or MIC, this memory chip provides a direct and immediate connection to the tape drive’s on-board processors to enable quick media load, fast access to user files and provide a wealth of data about the history and current state of the data cartridge.

2.3.8. Error Rate

The un-correctable bit error rate is expected to be less than 1 in 10 to the 17th.

2.3.9. Retry Limits on Rewrites

For Read-after-Write error correction, each frame can be rewritten up to a maximum of 63 times giving 64 writes of the frame.

2.3.10. Definition of Failure

A failure is defined as any permanent manufacture of the drive that prevents the user from retrieving data from tape. This includes failure to power up, failure to unload or eject a cassette, or failure to write and read data to and from the tape, providing that both the drive and tape are being used within specification.

Faults are not considered failures when they are related to operator error mishandling and abuse, system-related faults (cabling problems unsupported systems, operating software and so on) no trouble found, and transportation damage.

2.3.11. Mean Time Between Failures

The Mean Time Between Failures (MTBF) for the SDX-460V is 300,000 power-on hours, assuming a duty cycle of 100%, where:

2.4. Safety

The SDX-460V conforms to the following safety Standards:

• UL/cUL (Underwriters Laboratories, Inc.) UL 60950 3rd Edition/CSA C22.2 No. 60950-00 Safety of Information Technology Equipment.

• TUV EN 60950: 2000 Safety of Information Technology Equipment.

• CE Mark

2.4.1. Conditions of Acceptability

The SDX-460V is for use only in equipment where the suitability of the combination has been determined by an appropriate certification organization (for example, Underwriters Laboratories, Inc. or the Canadian Standards Association in North America, and the British Standards Institution or Verband Deutscher Elektrotechniker in Europe). Other considerations include the following:

1. An enclosure must be supplied to limit the operator’s access to live parts, to provide system stability, and to furnish the drive with the necessary grounding integrity.

2. The necessary voltage supplies must be provided. These supplies are Extra Low Voltage SEC for UL and CSA, or Safety Extra Low Voltage for BSI, VDE, and so on, of +5V and +12V DC.

Note: Voltage has to increase constantly during Power-up until Maximum is reached.

Do not turn off the drive while the tape is in the drive.

2.6. Data Compression

The tape capacity is increased by compressing data prior to writing it to the tape. Data compression is a well established technology for reducing the number of bits used to represent data in order to improve data transfer rate as well as reduce the amount of storage space consumed by the data. The compression ratio depends on the source file type. The SDX-460V uses the ALDC Data Compression algorithm. ALDC is ECMA standard data compression algorithm. (ECMA-222) The Data Compression control page allows the host computer to enable data compression and decompression and also configure the way in which the drive responds to compressed/uncompressed data boundaries on the tape. The AIT-E Turbo, AIT-1 Turbo and AIT-1 Format allows both compressed and uncompressed data to reside on the same tape.

The Sony SDX-460V has a DIP switch to disable the Data Compression/ Decompression. After power-on reset with this DIP switch set, both data compression and data decompression are disabled However, a MODE SELECT command can override the setting of this DIP switch. After power-on reset without this DIP switch set, both data compression and data decompression are enabled. (See clause 3.1.5)

4. Operation

4.2. Operator Action

4.2.1. Powering Up the SDX-460V

After the initial installation of the SDX-460V has been verified, power can be applied to the unit. The +12V and +5V power must be applied simultaneously. (See Figure 2-5) The SDX-460V will execute a power-up diagnostic and then comes ready.

Once the tape has been loaded the SDX-460V sends a CHECK CONDITION response on receipt of the next ATA/ATAPI command from the host. The UNIT ATTENTION key is set in the returned REQUEST SENSE data to indicate that the tape may have been changed. (Sense Key/ASC/ASCQ = 06/28/00)

4.2.2. Inserting Cassettes

The operator inserts a cassette into the slot on the front panel. As the cassette is inserted, the drive takes it and automatically loads it into the drive mechanism. The SDX-460V performs a tape load sequence as described in clause 4.3.1

4.2.3. Removing Cassettes

The cassette can be removed from the SDX-460V either in response to a ATA/ATAPI UNLOAD command, or by pressing the Eject button. The operator uses the Eject button to initiate the unload sequence (see clause 4.3.2). The mechanism winds the tape to Beginning of Media (BOM), unthreads it, and ejects the cassette from the slot.

Operation of the Eject button is disabled if the host has previously sent an ATA/ATAPI PREVENT ALLOW MEDIA REMOVAL command with prevent bit set to one. In this case, pressing the Eject button has no effect, and does not initiate an Unload sequence. The Eject button returns to normal operation following receipt of an PREVENT ALLOW MEDIA REMOVAL command with prevent bit clear.

4.2.4. Hard Reset Hole

Hard reset hole

In case of emergency, you can immediately reset the drive itself by pushing the switch in the “Hard Reset Hole” with the tip of a pin. However, there is a risk of losing data upon execution of this operation in the Write or Read mode. The hardware reset operation is only for manufacturing and repair purposes.

4.2.5. Write-Protecting Cassettes

Cassettes can be write-protected by sliding the tab on the back of the cassette open. In this state, data can be read from the tape but not written to it.



4-2

SONY AIT-1 Turbo drive SDX-460V series Ver.1.0

4. Operation

Caution: The Tape Log, which contains a history of usage of the tape, will not be updated when the cassette is write-protected. It follows that the Tape Log becomes inaccurate if a cassette is used write-protected, and the media warning cannot be relied on to indicate that the cassette needs to be copied and replaced.

4.3. Internal Function

4.3.1. The Load Sequence

14.2.1 Fast Media Load/Unload (Effective for SDX1-25C, SDX1-35C and TAIT1-40C, MIC cassette)

During load sequence, the following occurs: (1) The drive mechanism accepts the cassette and threads the tape. The tape is then moved to Beginning-of-Tape

(BOT) and the Reference area is checked to find the tape format. If the format is not AIT-1, the drive rewinds

the tape to BOT and awaits either a Write, Partitioning, Mode Select or an UNLOAD command. (2) The System area is then accessed and the System log is read into the drive. (3) Finally the drive goes on-line. In the case of 2 partition tape the drive detects that the tape has been formatted as a two partition tape when the

Reference Area is read. The drive will then automatically position to the beginning of partition 0 before coming on

-line. Partition 0 is the partition that begins the furthest from BOM.

(Effective for SDX-T3N, TAITE-20N and TAIT1-40N) Refer to

4.3.2. The Unload Sequence (Effective for SDX-T3N, TAITE-20N and TAIT1-40N) Refer to

14.2.1 Fast Media Load/Unload (Effective for SDX1-25C, SDX1-35C and TAIT1-40C, MIC cassette)

The drive will always write any buffered data out to tape followed by an EOD prior to initiating the Unload sequence. During this sequence the tape is rewound to BOT and, if the tape is write-enabled, the copy of the tape log held in

RAM is written back to tape. The tape is then rewound to BOM and the tape unthreaded from the mechanism. At this stage the tape is either retained in the drive or ejected, depending on media removal is enabled by the Prevent Allow Media Removal command.

In the case of two partition tape the drive detects that the tape has been formatted as a two partition tape when the Reference Area is read during the load sequence. When the Unload operation begins the drive will then automatically update the Tape Log for each partition before unloading the tape.

4.3.3. Power-Fail Handling

If there is a power-fail, the SDX-460V performs the following actions, and reverts to its default configuration: (1) The drive remains positioned at the point where the power-fail. (2) It executes the Power-Up sequence of self-tests. (When power is restored.) (3) If a tape is in the drive, the SDX-460V starts a LOAD sequence. The drive rewinds the tape to BOT and remains

on-line. (4) The drive returns CHECK CONDITION status for the first command after the power-fail or Reset. The next

command from the initiator should be a REQUEST SENSE. The drive will return sense data including a sense

key that will indicate that the drive has been reset. (Sense Key/ASC/ASCQ = 06/29/00)

4.3.4. Diagnostic and Normal Status Displays

This chapter describes LED displays while the SDX-460V is starting up. When power is turned on, the SDX-460V will go through its diagnostics to reach normal status. When a failure is detected during diagnostics, the LEDs show that the SDX-460V is out of order and needs to be repaired.

Note: When power is turned on, the all LED on before the front panel test.

This function is for checking TAPE MOTION, CLEANING REQUEST, REPLACE TAPE LEDs and the related circuits. No errors can be generated as this test is only for operator verification of indicator operation.

Kernel Test

After the Front Panel Test, the SDX-460V checks its internal units. When a Diagnostic error occurs, all LED flash fast. Then the SDX-460V must be powered off. The SDX-460V will not work and should be checked or repaired immediately.

The purpose of the diagnostic firmware to test the SDX-460V electronics for functionality. If the diagnostic request comes from the host through IDE, then the results are reported through IDE.

If the electronics are not functioning, the diagnostic firmware tries to isolate the non-functional area to a specific Failed Unit. Given a failure, the firmware decides on an hierarchical basis which Unit to designate as the Most Suspect Failed Unit (MSFU). The confidence in this decision is intended to be 95%. For the details of Diagnostics, see clause 7.2.6

4.3.4.2. Normal Status Display

After the Diagnostic Display, when no failures are detected, the SDX-460V is in the Normal Status. The LEDs show various Normal Status (No Error) indications as shown in the table below:

4.4. Tape Format

The SDX-460V is an implementation of the Advanced Intelligent Tape (AIT-E Turbo, AIT-1 Turbo and AIT-1) format, a standard developed by Sony for 8mm data storage drives.

- C1,C2, first and second level Error Correction Code, providing correction for random and Burst Symbol errors.

- C3 ECC, third level Error Correction Code, providing correction across frames within groups

- Read-After-Write, where data is verified immediately after it is written and re-written if there is any error.

- Randomizer, to reduce inter-symbol interference.

4.4.1. Tape Partitions

Tapes can be formatted as a single data space or as two partitions. With two partitions, each has the same structure and can be written independently. Some for example, the partition further from BOM (Partition 0) can contain data files, and the partition closer to BOM (Partition 1) could contain a directory of these files, written later.

With the exception of the Device area on the tape, each partition of a 2-partition tape is identical to a single data space tape in structure. This means each partition has its own Tape Log area; this is necessary because the patterns of usage may be very different for each partition. Similarly, each has its own Vendor Group, because the partitions might be written by different drives.

4.4.1.1. Formatting Partitions

The ATA/ATAPI MODE SELECT command is used to create partitions on a tape. The command can perform the following operations:

- Set up two partitions on a blank tape.

- Convert a single data space tape to a 2-partition tape.

- Convert a 2-partition tape to a single data space tape.

- Change the size of both partitions on a 2-partition tape.

- Re-size the partitions of a 2-partition. Note: Formatting is not needed for single partition operation.

The MODE SELECT, Medium Partitions Parameters Page (11h) is used to Format the tape. MODE SELECT, Device Configuration Page (10h) is used to change from one partition to another, see the MODE SELECT Command description in the ATA/ATAPI command clause of this manual. The LOCATE Command also has the capability to select a partition prior to positioning.

Any data on the tape before the format pass becomes inaccessible, even if the format pass is intended only to change the size of the two partitions. The Tape Logs are also destroyed and new logs created.

If you do not format a new tape, it will be organized as a single data space tape. After data has been written to it, whether it was first initialized or not, a format pass is necessary to alter its characteristics and hence how it is handled by the tape drive system.

Note: The format operation can be very time consuming depending on the requested size of the first partition on the tape. The amount of time required can be approximated by use of the following formula:

- Number of Megabytes in Partition 1 × 0.006 = number of minutes required

- Add 30 additional seconds for processing overhead

4.5.1. Head Cleaning

In case of SDX-460V,a cleaning function which prevents and recovers from head contamination is built in the drive. However, to keep optimum Read/Write performance, cleaning cassette is recommended to use.

4.5.1.1. Message When Cleaning Cassette is Necessary

When drive displays cleaning cassette requirement, (Cleaning Request LED is on or in case of ATA/ATAPI, CLN bit is set at Request Sense.) use specified cleaning cassette (model name : SDX1-CL )

4.5.1.2. The Condition of Cleaning Request

(1) Read/Write performance decreased. (2) Every 100 hours of operation

Note: (2) is enable when Periodic Cleaning Req Dip-SW is on.(Refer to 3.1)

4.5.1.3. Usage of Cleaning Cassette

(1) Drive displays cleaning cassette requirement. (2) When specified cleaning cassette is inserted, automatic cleaning operation starts and when its over, the

cassette is ejected. (3) One cleaning cassette can be used approximately 60 times. (4) When the Cleaning Request LED indicates "Cleaning is Not Completed", it is possible that there were no more

cleaning tape left. Since cleaning tape cannot be used twice, please insert new cleaning cassette in this case. (5) SDX1-CL can be inserted in other drives or consumer 8 mm drives, but you cannot expect good effect. (6) The drive will automatically eject cleaning cassette for consumer drives or for any other format. The cleaning

Request is indicated by the Starts LED flashing:

- on for 3.5 seconds

- off for 0.5 seconds

4.5.2. Troubleshooting Guide

Problems encountered while operating the Sony SDX-460V tape drive fall into two categories: Operational problems and Read/Write problems.

Operational problems include any conditions that prevent the tape drive from operating. Operational problems usually are discovered the first time the drive is installed on a system or when the system configuration is changed or physically moved.

Read/Write problems include conditions that effect the transfer of data to and from the tape drive. Commands such as REWIND, REQUEST SENSE and UNLOAD perform normally but data transfers fail.

The following clauses describe the recommended procedures for solving operational and read/write problems.

4.5.2.1. Operational Problems

The tape drive will not accept a tape cartridge

Withdraw the tape cassette and turn the power to drive off, wait 5 seconds, then back on. Observe the drive for a normal power up sequence (see clause 4.3.4). If the LEDs do not light, check the power supply and power cable connection. If the drive completes the power on sequence normally but still won’t accept the tape cassette, the drive may be defective.

A tape may already be in the drive. TAPE MOTION LED is on. Press EJECT to remove the first tape. The power has been removed from the drive with a tape loaded. When the power is restored to the drive, it will detect the tape and rewind the tape to BOT. Press EJECT remove the cassette.

4. Operation

A tape is in the drive and will not eject.

If the ATA/ATAPI command PREVENT ALLOW MEDIA REMOVAL (with Prevent bit set to one) has been sent to the drive, the cartridge will be retained in the drive even after an UNLOAD command. The EJECT button is also disabled. Send an PREVENT ALLOW MEDIA REMOVAL (with prevent bit clear) command, or power the drive off and back on to override this condition.

If Tape is still in the drive after following the above procedure. The drive has a serious problem and should be returned to Sony for repair with the tape in place.

Note: If it is absolutely mandatory that the tape cassette be removed prior to returning the drive for repair the following Emergency Cassette Removal procedure should be followed:

Caution: This procedure should only be attempted by a mechanically qualified person and will probably result in the tape being unusable. Do not proceed if further damage to the tape drive would be done.

mechanism located on the bottom of the drive counterclockwise to tighten the tape.

6. After the tape slack has been removed, continue to turn the Loading moter shaft located on the bottom of the

drive clockwise by a precision screwdriver until the tape cartridge is lifted out of the drive mechanism and is ejected.

7. Return the drive to Sony for repair.

The drive powers up properly and loads and unloads tapes but will not respond to any ATA/ATAPI commands.

If host does not recognize the tape drive:

- Check the IDE cable connectors

- Check Jumper setting

- Check IDE cable pin one is aligned with the IDE connector pin one

- Check for a broken cable or defective connector

- Try another known good IDE device in the same location

4.5.2.2. Read/Write Problems

To prevent read/write errors, follow the cleaning recommendation in clause 4.5.1 If a read/write error occurs, a combination of the following steps should correct the problem.

- Remove the tape.

- Clean the drive with the AIT cleaning cartridge.

- Load a new tape in the drive.

- Retry the operation. Note: If these steps do not correct the problem the drive may be defective and should be returned to Sony for

service.

4.5.2.3. Replace Tape

When Media Error occur drive will indicate that tape is bad by turning on the Replace Tape LED. If this condition occurs, a combination of the following steps should correct the problem.

- Remove the tape.

- Clean the drive with the AIT cleaning cartridge.

- Load a new tape in the drive.

- Retry the operation. Note: If these steps do not correct the problem the drive may be defective and should be returned to Sony for

service.

4.5.2.4. Media Warning

When a Media Warning threshold is exceeded the drive will indicate that the tape is bad by flashing the Replace Tape LED MEW(Media Warning) bit is 1. The indicator will be on for 0.9 seconds, off for 0.3 seconds. The Tape Motion and Cleaning Request LEDs will operate normally. If this occurs, the data on the cassette should be copied onto a new one and the old cassette discarded. This status is cleared by unloading the cassette. The Media Warning is displayed if any of the following conditions are met:

- More than 1,024 RAW retry per 1,024 groups written

- More than 11 read retry or 11 C3 ECC, third level Error Correction Code, per 1,000 groups read Note: Media warning is calculated as an average value of 1024 groups of data (either Read of Write) 1024 Groups of

data is approximately 1.2 Gbyte.

4.5.3. Clearance for Service

All servicing is performed only after removal of the SDX-460V from is mounting. It is recommended that in mounting the drive into a chassis provisions should be made to allow easy access to the mounting screws (see Figure 2-2).

4.5.4. Packaging for Return to Sony

The drive should be returned in its original packaging. Sony will not take responsibility for shipping damage caused to an improperly packaged drive.

5. ATA/ATAPI Interface

5.1. Introduction

The SONY SDX-460V ATAPI TAPE DRIVE uses the ATA Packet Interface (ATAPI) to connect to the host system. ATAPI is an industry standard interface, approved by the American National Standards Institute (ANSI). It is recommended that this document be used along with the ANSI standard document. The ANSI specification defines the interface in general while this document describes the specific implementation for this unit. The ATA/ATAPI documents, listed in detail in section 1.2, offer the information required to integrate this unit with ATAPI compatible computer systems.

The Introduction provides general, high-level information. For the hardware description and the installation requirements, see section 2.

5.2. Overview of Interface

The ATAPI implementation provides the unit with a standard set of features and functions. These include:

• Support for 2 devices (master and slave)

• Registers for passing command and control information

• Device addressing considerations

In traditional controller operation, only the selected device receives commands from the host following selection. For ATAPI devices, when a register is written, the value is written to the register of both devices. The host discriminates between the two by using the DEV bit in the Device/Head register. When the DEV bit is cleared to zero, Device 0 is selected. When the DEV bit is set to one, Device 1 is selected. When two devices are connected to the cable, one shall be set as Device 0 and the other as Device 1

The devices using this interface shall be programmed by the host computer to perform commands and return status to the host at command completion. Commands may be delivered in two forms. ATAPI devices use the PACKET Command feature set which utilizes packet delivered commands as well as some register delivered commands. Register delivered commands and command parameters are delivered by writing the device Command Block registers.

When two devices are connected on the cable, commands are written in parallel to both devices, and for all except the EXECUTE DEVICE DIAGNOSTIC command, only the selected device executes the command. Both devices shall execute an EXECUTE DEVICE DIAGNOSTIC command regardless of which device is selected, and Device 1 shall post status to Device 0 via PDIAG-.

When the Device Control register is written, both devices respond to the write regardless of which device is selected.

Data is transferred in parallel either to or from host memory to the device’s buffer under the direction of commands previously transferred from the host. The device performs all of the operations necessary to properly write data to, or read data from, the media. Data read from the media is stored in the device’s buffer pending transfer to the host memory and data is transferred from the host memory to the device’s buffer to be written to the media.

5.2.1. Device Registers

The Command Block registers are used for sending commands to the device or posting status from the device. These registers include the Cylinder High, Cylinder Low, Device/Head, Sector Count, Sector Number, Command, Status, Features, Error, and Data registers. The Control Block registers are used for device control and to post an alternate status. These registers include the Device Control and Alternate Status registers.

Alternate Status register

This register contains the same information as the Status register in the command block.

Command register

7 6 5 4 3 2 1 0

Command Code

This register contains the command code being sent to the device. Command execution begins immediately after this register is written.

Cylinder High register

The content of this register is command dependent and becomes a command parameter when the Command register is written.

Cylinder Low register

The content of this register is command dependent and becomes a command parameter when the Command register is written.

Data port

The data port is 16-bits in width. DMA out data transfers are processed by a series of reads to this port, each read transferring the data that follows the previous read. DMA in data transfers are processed by a series of writes to this port, each write transferring the data that follows the previous write.

Data register

The data register is 16-bits wide. PIO out data transfers are processed by a series of reads to this register, each read transferring the data that follows the previous read. PIO in data transfers are processed by a series of writes to this register, each write transferring the data that follows the previous write.

Device Control register

This register allows a host to software reset attached devices and to enable or disable the assertion of the INTRQ signal by a selected device. When the Device Control register is written, both devices respond to the write regardless of which device is selected. When the SRST bit is set to one, both devices shall perform the software reset protocol. The device shall respond to the SRST bit when in the SLEEP mode. When the nIEN bit is set or cleared, both devices shall disable or enable assertion of the INTRQ signal.

7 6 5 4 3 2 1 0

r r r r r SRST nIEN 0

- Bits 7 through 3 are reserved.

- SRST is the host software reset bit.

- nIEN is the enable bit for the device interrupt to the host. When the nIEN bit is cleared to zero, and the device is selected, INTRQ shall be enabled through a tri-state buffer and shall be asserted or negated by the device as appropriate. When the nIEN bit is set to one, or the device is not selected, the INTRQ signal shall be in a high impedance state.

- Bit 0 shall be cleared to zero.

Features register

The content of this register is command dependent and becomes a command parameter when the Command register is written.

Sector Count register

The content of this register is command dependent and becomes a command parameter when the Command register is written.

Sector Number register

The content of this register is command dependent and becomes a command parameter when the Command register is written.

Status register

This register contains the device status. The contents of this register are updated to reflect the current state of the device and the progress of any command being executed by the device.

7 6 5 4 3 2 1 0

BSY DRDY # DSC DRQ obsolete obsolete ERR

BSY is set to one to indicate that the device is busy. After the host has written the Command register the device shall have either the BSY bit set to one, or the DRQ bit set to one, until command completion or the device has performed a bus release for an overlapped command.

DRDY is set to one to indicate that the device is ready to accept a new command. DSC is used with ATAPI packet commands to provide efficient use of the IDE bus by allowing overlapped

commands to be sent to the other IDE Device on the same cable while the SDX-460V is executing a command. This field is not supported.

SONY AIT-1 Turbo drive SDX-460V series Ver.1.0

5. ATA/ATAPI Interface

DRQ indicates that the device is ready to transfer a word of data between the host and the device. After the host has written the Command register the device shall either set the BSY bit to one or the DRQ bit to one, until command completion or the device has performed a bus release for an overlapped command.

ERR indicates that an error occurred during execution of the previous command. For the PACKET and SERVICE commands, this bit is defined as CHK and indicates that an exception condition exists.

5.2.2. Interrupts

INTRQ is used by the selected device to notify the host of an event. The device internal interrupt pending state is set when such an event occurs. If nIEN is cleared to zero, INTRQ is asserted. The device shall enter the interrupt pending state when:

1. any command except a PIO data-in command reaches command completion successfully;

2. any command reaches command completion with error;

3. the device is ready to send a data block during a PIO data-in command;

4. the device is ready to accept a data block after the first data block during a PIO data-out command;

5. a device implementing the PACKET Command feature set is ready to receive the command packet and

bits 6-5 in word 0 of the IDENTIFY PACKET DEVICE response have the value 01b;

6. a device implementing the PACKET Command feature set is ready to transfer a DRQ data block during

a PIO transfer;

7. a device implementing the Overlap feature set performs a bus release if the Bus release interrupt is

enabled;

8. a device implementing the Overlap feature set has performed a Bus release and is now ready to

continue the command execution;

9. a device implementing the Overlap feature set is ready to transfer data after a SERVICE command if the

Service interrupt is enabled;

10. Device 0 completes an EXECUTE DEVICE DIAGNOSTIC command. Device 1 does not enter the

interrupt pending state when completing an EXECUTE DEVICE DIAGNOSTIC command. The device shall not exit the interrupt pending state when the device is deselected. The device shall exit the interrupt pending state when:

1. the device is selected, BSY is cleared to zero, and the Status register is read;

2. the device is selected, both BSY and DRQ are cleared to zero, and the Command register is written;

3. the RESET- signal is asserted;

4. the SRST bit is set to one.

Identify Packet Device 6. ATA Command Specification

When the command is issued, the Sony ATAPI Tape Drive sets the BSY bit to one, prepares to transfer the 256 words of device identification data to the host, sets the DRQ bit to one, clears the BSY bit to zero, and generates an interrupt. The host may then transfer the data by reading the Data register. Table 6-3: Identify Packet Device information defines the arrangement and meanings of the parameter words in the buffer. All reserved bits or words are zero.

Some parameters are defined as a group of bits. A word that is defined as a set of bits is transmitted with indicated bits on the respective data bus bit (e.g., bit 15 appears on DD15).

Some parameters are defined as a 16-bit value. A word that is defined as a 16-bit value places the most significant bit of the value on bit DD15 and the least significant bit on bit DD0.

Some parameters are defined as 32-bit values (e.g., words 57 and 58). Such fields are transferred using two word transfers. The Sony ATAPI Tape Drive transfers the least significant bits first, bits 15 through 0 of the value, on bits DD (15-0) respectively. After the least significant bits have been transferred, the most significant bits, bits 31 through 16 of the value, are transferred on DD (15-0) respectively.

Some parameters are defined as a string of ASCII characters. For the string “Copyright”, the character “C” is the first byte, the character “o” is the 2nd byte, etc. When such fields are transferred, the order of transmission is: the 1st character (“C”) is on bits DD (15-8) of the first word, the 2nd character (“o”) is on bits DD (7-0) of the first word, the 3rd character (“p”) is on bits DD (15-8) of the second word, the 4th character (“y”) is on bits DD (7-0) of the second word, etc.

Packet 6. ATA Command Specification

6.8. Packet (A0h)

The PACKET command is used to transfer a device command via a command packet (See section 6.1 for command packet descriptions). If the native form of the encapsulated command is shorter than the packet size reported in bits 1 and 0 of word 0 of the IDENTIFY PACKET DEVICE response, the encapsulated command shall begin at byte 0 of the packet. Packet bytes beyond the end of the encapsulated command are reserved. If the device supports overlap, the OVL bit is set to one in the Features register and the Release interrupt has been disabled via the SET FEATURES command, the device may or may not perform a bus release. If the device is ready for the data transfer, the device may begin the transfer immediately as described in the non-overlapped protocol. If the data is not ready, the device may perform a bus release and complete the transfer after the execution of a SERVICE command.

These fields are not applicable.

Byte count low and Byte count high registers -

These registers are written by the host with the maximum byte count that is to be transferred in any single DRQ assertion for PIO transfers. The byte count does not apply to the command PACKET transfer. If the PACKET command does not transfer data, the byte count is ignored.

If the PACKET command results in a data transfer:

a) the host shall not set the byte count limit to zero. If the host sets the byte count limit to zero the

device sets the limit to FFFEh; b) the value set into the byte count limit maybe even or odd; c) the value FFFFh is interpreted by the device as though it were FFFEh.

Set transfer mode

A host selects the transfer mechanism by Set Transfer Mode, subcommand code 03h, and specifying a value in the Sector Count register. The upper 5 bits define the type of transfer and the low order 3 bits encode the mode value. One PIO mode and one DMA mode shall be selected at all times. Therefore, if a Multiword DMA mode is selected then no UDMA mode is selected and if a UDMA mode is selected, no Multiword DMA mode is selected. The host may change the selected modes by the SET FEATURES command.

Note: Issuing the set features transfer mode command only selects the speed for the particular type of

transfer. It does not select the transfer operation. The use of DMA for packet commands is selected with the Packet command. See Packet Command (A0h) section 6.1.

Enable/disable reverting to defaults

Subcommand codes CCh and 66h are implemented for compliance with the ATAPI-6 standard. These commands do not affect the operation of the SDX-460V, and should never return error.

If the SDX-460V ATAPI Tape Drive receives a SET FEATURES command with a Set Transfer Mode parameter and a Sector Count register value of “00000000b”, it sets its default PIO mode. If the value is “00000001b”, the Sony ATAPI Drive sets its default PIO mode and disable IORDY. The SDX-460V supports all PIO modes below the highest mode supported.

Signature and Persistence

A device implementing the PACKET command feature set shall place the signature in the Command Block registers listed below for power on reset, hardware reset, software reset, the EXECUTE DEVICE DIAGNOSTIC command, and the DEVICE RESET command. The DEVICE RESET command shall not change the value of the DEV bit when writing the signature into the Device/Head register for a device implementing the PACKET command feature set. If the device implements the PACKET command feature set, the signature is also written in the registers for the IDENTIFY DEVICE and READ SECTOR(S) commands.

This device implements the PACKET command feature set, therefore the signature shall be:

Table 6-6: ATAPI Identification Signature

Sector Count 01h

Sector Number 01h

Cylinder Low 14h

Cylinder High EBh

The PACKET command feature set is implemented by this device, therefore the signature values written by the device in the Command Block registers following power on reset, hardware reset, software reset, or the DEVICE RESET command shall not be changed by the device until the device receives a command that sets DRDY to one. These commands are a PACKET command or an IDENTIFY PACKET DEVICE command. Writes by the host to the Command Block registers that contain the signature values shall overwrite the signature values and invalidate the signature.

The ERASE command causes part or all of the medium to be erased beginning at the current position. As used here, “erased” means either the medium shall be erased or a pattern shall be written on the medium that indicates the end of recorded data.

An Immed (immediate) bit of zero indicates the Device shall not return status until the operation has completed. An Immed bit of one indicates that the target shall return status as soon as all buffered commands have completed execution and the CDB has been validated. If CHECK CONDITION status is returned when the Immed bit is set to one, the operation shall not be performed.

Long: The Long bit controls the distance to be erased. The drive will always erase data from its current logical position and then write 300 frames of EOD. If this bit is set, an EOD is written to the end of the current partition.

The INQUIRY command requests that information regarding parameters of the Device be sent to the Host. An option allows the Host to request additional information about the Device.

CmdDT: The Command support data (CmDT) bit of one specifies that the drive returns the optional support data specified by the operation code field.

If both the CmDT and EVPD bits are zero, the drive returns the standard INQUIRY data. If the page or operation code field is not zero when both CmdDT and EVPD are zero, the drive returns a CHECK CONDITION status with an ILLEGAL REQUEST Sense Key.

If the CmdDT and EVPD bits are one, the drive returns a CHECK CONDITION status with an ILLEGAL REQUEST Sense Key.

When the EVPD bit is set to one, the drive returns vital product data that is specified in the page or operation code field. If the page or operation code field is reserved or not implemented by the target, the target shall terminate the command with a CHECK CONDITION status. The sense key shall be set to ILLEGAL REQUEST.

When the CmdDT bit is set to one, the page or operation field specifies the operation code for which the drive shall return support data.

EVPD: The Enable Vital Product Data (EVPD) bit of one specifies that the drive returns the optional vital product data specified by the page code field.

Allocation Length: This specifies the maximum number of bytes that the host has allocated for returned Inquiry data. An Allocation Length of ZERO indicates that no Inquiry data is transferred. This condition is not considered an error. The drive will terminate the data transfer when Allocation Length bytes have been transferred or when all available Inquiry data have been transferred to the host, whichever is less.

The INQUIRY command shall return “Check Condition” status only when the Device cannot return the requested INQUIRY data. The INQUIRY data should be returned even though the Device may not be ready for other commands.

If an INQUIRY command is received with a pending unit attention condition (i.e. before the Device reports “Check Condition” status), the Device shall perform the INQUIRY command and shall not clear the unit attention condition.

The LOAD/UNLOAD command requests that the Device enables or disables further media access operations. This command may also be used to request a re-tension function. Prior to performing the load or unload operation, the Device shall ensure that all buffered data, and filemarks have been transferred to the medium.

An Immed (immediate) bit of zero indicates the Device shall not return status until the operation has completed. An Immed bit of one indicates that the Device shall return status as soon as all buffered commands have completed execution and the CDB has been validated. If CHECK CONDITION status is returned when the Immed bit is set to one, the operation shall not be performed.

A Re-Tension (Re-Ten) bit of one indicates that the medium on the Device shall be correctly tensioned. EOT: An end-of-tape (EOT) bit of one and a Load bit of ZERO indicates that the medium shall be positioned at

end-of-medium for removal from the peripheral device. Prior to performing the unload operation, any buffered data that is to be written shall be transferred to the medium. An EOT bit of ZERO and Load bit of ZERO indicates that the medium shall be positioned at beginning-of-medium for removal etc. An EOT bit of one and a Load bit of one shall cause the drive to return CHECK CONDITION status. The sense key shall be set to ILLEGAL REQUEST and the additional sense code shall be set to ILLEGAL FIELD IN CDB.

If the Load bit is set to one, the medium shall be loaded and positioned to the beginning-of-partition zero. If the Load bit is zero, the medium in the Device shall be positioned for removal at the extreme position along the medium. Following successful completion of an unload operation, the Device shall return “Check Condition” status with the Sense Key set to NOT READY for all subsequent medium-access commands until a new volume is mounted or a load operation is successfully completed.

PREVENT MEDIA REMOVAL (with prevent bit set) command, the tape is retained in the drive. A subsequent LOAD command will load and position the tape at BOP ZERO. If an UNLOAD were sent instead, the drive would return NOT READY and the tape would remain within the drive. In this case, the drive requires a PREVENT ALLOW MEDIA REMOVAL (with prevent bit clear) command before an UNLOAD will eject the tape.

Note: While the PREVENT MEDIA REMOVAL is in effect, the Front Panel EJECT button is completely disabled. If the cassette is unloaded but has not been ejected from the drive because of moisture detection, then a

subsequent UNLOAD will cause the tape to ejected from the drive. All commands except INQUIRY, REQUEST SENSE and READ BLOCK LIMITS will return a CHECK CONDITION status with a HARDWARE ERROR sense key set. The tape may also be ejected via the Front Panel EJECT button. If no cassette is in drive, both LOAD and UNLOAD will return a CHECK CONDITION status with NOT READY sense key set

The LOG SELECT command provides a means for the Host to manage statistical information maintained by the device about its own hardware or the installed media. This description should be read in conjunction with the description of the LOG SENSE command which follows it, to provide the reader with information about log page format, parameters and supported pages.

PCR: A Parameter Code Reset bit of one and a Parameter List Length of ZERO will cause ALL log pages which can be cleared, to be cleared. If this field is set and the Parameter List Length field is non-ZERO then the command will be terminated with a CHECK CONDITION status with the sense key set to ILLEGAL REQUEST, and an additional sense code of INVALID FIELD IN CDB.

SP: The device does not have non-volatile RAM into which it may save parameters. Therefore, the Save Page bit is not supported by this device and shall always be set to ZERO. If the SP bits is set, the command will be terminated with CHECK CONDITION status with the sense key set to ILLEGAL REQUEST, and an additional sense code of INVALID FIELD IN CDB.

If this field is set to 00b, 10b or 11b and the Parameter List Length field is non-0 then the command will be terminated with a CHECK CONDITION status with the sense key set to ILLEGAL REQUEST, and an additional sense code of INVALID FIELD IN CDB. This is because no modification of these log pages are permitted. For a description of command behavior if this field is set to 01b then see the description of the Parameter List Length field below.

If this field is set to 10b and the Parameter List length field is 0 then all Current Threshold Values will be reset to the Default Threshold Values. This is equivalent to no change as Threshold Values cannot be modified.

If this field is set to 11b and the Parameter List Length field is 0 then all Current Cumulative Values will be reset to the Default Cumulative Values. This is equivalent to all log pages which can be cleared.

7. ATAPI Packet Command Specification LOG SELECT

Parameter List Length: This field specifies the length in bytes of the LOG SELECT parameter list that shall be transferred from the initiator to the target during the DATA OUT phase. A parameter list length of ZERO indicates that no data shall be transferred. This condition shall not be considered as an error (see description of Parameter Code Reset and Page Control fields above). If this field is non-0 the Page Control field must be 01b.

The purpose of the Log Select command is to allow the host to modify and initialize parameters within the logs supported by the device. However in this case, assess to individual parameters within log pages is not supported and so only complete log pages may be reset.

To achieve this, the host must send the log page header of the page to be cleared, with the Page Length field set to ZERO. The following pages can be cleared in this manner.

Table 7-8: LOG PAGE Page Codes

Page Code Description

02h Write Error Counter Page 03h Read Error Counter Page 07h Last n Error Events Page 34h Write Frame Error Counter Page 35h Read Frame Error Counter Page 39h Data Compression Transfer Log Page

Note: Due to the way in which logs are stored and updated, clearing log page 2 will result in log page 3 also being cleared and vice versa.

Because of this method of clearing the log pages, the Parameter List Length field must be an integer multiple of the Log Page Header length (i.e. 4). Otherwise the command will be terminated with a CHECK CONDITION status with the sense key set to ILLEGAL REQUEST and an additional sense code of INVALID FIELD IN CDB.

If multiple pages are sent during the Data Transfer then they must be sent in ascending order according to page code. Otherwise the command will terminate with a CHECK CONDITION status with the sense key set to ILLEGAL REQUEST and an additional sense code of ILLEGAL FIELD IN PARAMETER LIST. The same status will be returned if an unsupported Page Code appears in any header or if the specified page cannot cleared.

Other Log Select Page Codes have been defined for MIC support. MIC Variable Length Information Page is assigned as 3Eh. Please refer to the description for ”Log Sense Page 3Eh” in the Product Specification Manual. User Volume Note and User Partition Note is automatically created with indicated size, if it does not exist. User Volume Note size and User Partition Note size must be the same size with current one, if it is already exist. Just only supersede operation is allowed.

LOG SENSE provides a means for the Host to retrieve statistical information maintained by the device about its own hardware or the installed media. It is a complementary command to the LOG SELECT command.

SP: The device does not have non-volatile RAM into which it may save parameters. Therefore, the Save Page bit is not supported by this device and shall always be set to ZERO. If the SP bit is set, the command will be terminated with CHECK CONDITION status with the sense key set to ILLEGAL REQUEST, and an additional sense code of INVALID FIELD IN CDB.

PPC: The Parameter Pointer Control bit shall always be set to ZERO. This indicates that the parameter data requested from the device will start with the parameter code specified in the Parameter Pointer field and return the number of bytes specified in the Allocation Length field in ascending order of parameter codes from the specified log page. A PPC bit of ZERO and a Parameter Pointer field of ZERO cause all available parameter data for that page code to be returned to the initiator. If the PPC bit is set or the Parameter Pointer is larger than the highest numbered parameter on the page, then the target shall terminate the command with CHECK CONDITION status. The sense key shall be set to ILLEGAL REQUEST and the additional sense code shall be set to INVALID FIELD IN CDB. If the drive does not support a parameter code within this page then it shall not return any data associated with this parameter.

Parameter Pointer: The Parameter Pointer field allows the host to specify at which parameter within a log page the requested data should begin.

For example if a page supported parameters 0 through 5, and the Parameter Pointer field contained 3 then only parameters 3, 4 and 5 would be returned to the initiator. Similarly, if a page supported parameters 1, 3 and 6, and the Parameter Pointer field contained 2, then only parameters 3 and 6 would be returned to the initiator.

Note that parameters within a page are always returned in ascending order according to parameter code. If an invalid parameter pointer is sent the drive will return CHECK CONDITION with the sense key set to ILLEGAL REQUEST and an additional sense code of INVALID FIELD IN CDB.

Allocation Length: The Allocation Length field is used to inform the target how much space the initiator has allocated for data. The drive will give a CHECK CONDITION because of this. It will return whatever host requests, up to the total data. Note however that if this field is 0 then this is not considered an error and the device will just return a GOOD STATUS.

7.6.1. The Log Page Descriptor

The format of the log pages consists of ZERO or more variable-length parameter structures. Each page begins with a 4-byte header followed by ZERO or more variable-length parameter structures defined for that page. The Log Select command supports the ability to send ZERO or more log pages. The LOG SENSE command returns a single log page as specified in the Page Code field of the CDB.

Page code: Identifies which page of data is being transferred. If the Page Code field value is reserved or not

implemented by the target, the target shall terminate the command with a CHECK CONDITION status. The sense key shall be set to ILLEGAL REQUEST, and the additional sense code shall be set to INVALID FIELD IN PARAMETER LIST.

Page Length: The Page Length field indicates the total number of bytes that follow this byte. The value returned for this field depends on the value you specified for the Page Code and the Parameter Pointer in the CDB. This value is independent of what you specified for the Allocation Length. A Page Length value that results in the truncation of any parameter shall cause the target to terminate the command with CHECK CONDITION status. The sense key shall be set to ILLEGAL REQUEST and the additional sense code shall be set to INVALID FIELD IN PARAMETER LIST.

7.6.2. The Log Parameter Descriptor

Most log pages contain one or more special data structures called log parameters. These may be data counters which record the occurrence of certain events, or they may be more complex structures which describe activities or other events which occur within the device. Each parameter structure begins with a 4-byte parameter header followed by one or more bytes of parameter structure data. The 4-byte header is shown below:

Parameter Code: Identifies which parameter of data is being transferred. If the parameter code value is reserved or not implemented by the target, then the target shall terminate the command with CHECK CONDITION status. The sense key shall be set to ILLEGAL REQUEST and the additional sense code shall be set to INVALID FIELD IN PARAMETER LIST.

The DU, DS, TSD, ET, TMC, and LP fields are collectively referred to as the control byte. DU: The DU bit (Disable Update) is not defined for threshold values (indicated by the PC field of the LOG SENSE

command descriptor block). The target shall ignore the value of any DU bits in a LOG SELECT command. DS: The DS bit informs the initiator that savable parameters are disabled (i.e. not supported), and should always

be 1. If it is 0 the command will terminate with CHECK CONDITION status with sense key set to ILLEGAL REQUEST and additional sense code of ILLEGAL FIELD IN PARAMETER LIST.

LOG SENSE 7. ATAPI Packet Command Specification

TSD: A target save disable (TSD) bit of ZERO indicates a target-defined method for saving log parameters. This implicit saving operation shall be done frequently enough to insure that the cumulative parameter values retain statistical significance (i.e. across power cycles). A TSD bit of one indicates that either the target does not provide a target-defined method for saving log parameters or the target-defined method has been disabled by the initiator. If the initiator sets both the DS and the TSD bits set to one, the target shall terminate the command with CHECK CONDITION status . The sense key shall be set to ILLEGAL REQUEST with the additional sense code set to INVALID FIELD IN PARAMETER LIST.

ETC: An enable threshold comparison (ETC) bit of one indicates that when the cumulative parameter value is updated, it shall be compared to the threshold parameter value and the action specified by the TMC field shall be taken. An (ET) bit of ZERO disables this comparison. The ET bit is the same for both the cumulative and threshold log parameter. Thus when the ET bit is set to a value by the initiator, this value is returned for both the cumulative and threshold values of the log parameter.

TMC: The threshold met criteria (TMC) field defines the binary relationship between the cumulative and threshold log parameter values under which the threshold is met. If the ET bit is one and the threshold condition is met, a Unit Attention condition shall be posted to all initiators. When reporting the unit attention condition, the target shall set the sense key to UNIT ATTENTION, the additional sense code to LOG EXCEPTION, and the additional sense code qualifier to THRESHOLD CONDITION MET.

The TMC field is the same for both the cumulative and threshold parameter. Thus when the TMC field is set to a value by the initiator, this value is returned for both cumulative and threshold values of the log parameter.

LOG SENSE 7. ATAPI Packet Command Specification

This information is contained within RAM in the Drive Controller. When a cassette is loaded, the contents of the System Area are copied into this log. The log is updated as the tape is used and is copied back onto the System Area when the cassette is unloaded (if the tape is Write enabled).

Note: The System Area only contains ‘previous’ and ‘total’ information – (when the cassette is unloaded, the ‘current’ values become the System Area ‘previous’ values).

The term ‘current refers to information generated during the current load of the tape; ‘previous’ refers to information generated during the last tape load; ‘total’ refers to information generated during the life of the tape since it was first initialized including the current load.

Use: An estimate of reading and writing performance can be made by the ratios of ‘RAW retries’ to ‘groups written’ and ‘ECC-3 retries’ to ‘groups read’. An indication of tape degradation can be gained by comparing these ratios for ‘current’, ‘previous’ and ‘total’ entries.

Any attempt to change this page using LOG SELECT will result in a CHECK CONDITION with a Sense Key of ILLEGAL REQUEST. The current cumulative values will be returned regardless of the Page Control field n the LOG SENSE CDB.

7.6.7. Tape Capacity Log Page

The tape Capacity Log Page is used to indicate the approximate capacity of the tape currently being used. The PC field of the LOG SENSE command is ignored for this field.

When the AIT bit is set to ZERO in Mode Sense Page 31h, the 36 bytes of the log page shall be returned. When the AIT bit is set to ONE, the 1028 bytes of the log page shall be returned. The 36 bytes of the log page have the following format.

Note:

1. Parameter Code 0002h AIT Device Configuration Byte is the same byte value returned in Mode Sense Page 31h byte 2.

2. Parameter Code 0003h Available Free Byte Count represents the current user MIC memory that is available for writing data to the MIC using the Log Select command through Page 3Eh Parameter Code 0001h, 0002h, and 0003h. If Available Free Byte Count is 1 or higher the application may use exactly that size or smaller to write MIC User data. If this field is ZERO a Check Condition status is returned if attempts are made to write data to the MIC. If the application attempts to write data to the MIC that is larger than this field a Check Condition status will also be returned. In both cases where Check Condition status is returned no data is written to the MIC.

3. Parameter Code 0014h List of Partitions is a bit map field that represents all 256 partitions. Presently, for MIC Phase 1 only 2 partitions are supported. Only 2 partitions can have Partition Note data. Below is a diagram of the bit map ordering of the Partition Note data. A “1” in the bit field for the partition indicates there is Partition Note in MIC; a “0” in the bit field indicates there is no Partition Note in MIC for that partition. As an example, if partition 0 and partition 1 have Notes data Byte #0 below will be 0C0h, and Byte #1 to #31 will be 00h.
