What are the Drives?

The CFP1060 series are high performance 3.5-inch low-profile (1.0 inch high)

1.06 Gigabyte (formatted) disk drives. They all offer 9.0 millisecond average seek time for Reading , 9.5 millisecond seek time for Writing, with an average latency of only 5.55 ms. High capacity is achieved by utilizing a zone density recording technique using 9 recording zones at an areal density of 205 Mbits per square inch. These drives feature high performance while maintaining low power consumption to reduce power supply current and system cooling requirements in disk arrays.

They are designed to operate on the Small Computer System Interface (SCSI) and are SCSI-2/3 command compatible. The mechanical and major electronic components are identical between the models and differ only in the host interface implementation:

Overview of the Drives Chapter 1

Drive Assembly Housing

The drive assembly housing, or Head-Disk Assembly (HDA) consists of a die-cast aluminum base on which is mounted a die-cast aluminum cover. Both the base and the cover are coated with a special material designed to seal out contaminants which might degrade head and media reliability. A gasket seals the joint between the base and cover to retard the entry of moisture and environmental contaminants from the assembly.

This assembly, the head-disk assembly, contains an integral 0.3 micron filter, which maintains a clean environment. Critical drive components are contained within this contaminant-free environment. Figure 1-2 shows the HDA and the major assemblies contained within it:

Chapter 1 Overview of the Drives

Drive Motor and Spindle

A brushless DC direct-drive motor assembly is mounted on the drive’s base. The motor rotates the drive’s spindle at 5400 RPM. The motor/spindle assembly is dynamically balanced to provide minimal mechanical runout to the disks. A dynamic brake is used to provide a fast stop to the spindle motor and return the heads to the landing zone when power is removed.

Head Positioning Mechanism

The read/write heads are supported by a mechanism coupled to a rotary voice coil actuator.

Read/Write Heads and Disks

Data is recorded on 95mm diameter disks through 3370-type 50% nano-slider thin film heads with transverse pressure contour (TPC) air bearing surfaces. The TPC air bearing surface allows the head to fly at a uniform height regardless of radial position. This improves data reliability and allows the aerial density to be more uniform with radius. The drive contains four sputtered thin film disks with eight data surfaces and eight read/write heads.

At power-down, the heads are automatically retracted to the inner diameter of the disk and are latched and parked on a landing zone that is inside the data tracks.

Data and Power Connections

Data and power connections to the drive are differ between the drive models. Refer to chapter 4 for information regarding a specific model's requirements.

Electrical Design Features

Integrated Circuit

A single integrated circuit (IC) is mounted within the sealed hard drive assembly in close proximity to the read/write heads. The IC provides head selection, read pre-amplification, and write drive circuitry.

Circuit Board

The drive’s dual-microprocessor-controlled circuit board provides the remaining electronic functions, which include:

• read/write circuitry

• rotary actuator control

• interface control

• spin speed control

• auto-park

• power management

The background processor is a 16-bit Motorola 68HC16. The entire data path between the serializer-deserializer and the interface chip, including the buffer

Page 6 Filepro CFP1060E/CFP1060S/CFP1060W

Page 15

Overview of the Drives Chapter 1

(cache) is 16 bits wide to provide high data throughput. The "Catalina" SCSI interface chip manages a 16-bit to 8-bit conversion prior to transacting data over the SCSI bus for 8-bit narrow SCSI applications.

The data buffer (cache) utilizes a 256K x 16 Dynamic RAM. Data path integrity is ensured by using a 4-byte CRC which is appended to the data upon receipt by the Catalina. This CRC is verified by the "Indy" buffer manager when the data is taken out of the buffer to be written to the disk and the CRC is written with the data. A typical sector data field consists of 512 bytes of data, 4 bytes of CRC and 11 bytes of Error Detection And Correction (EDAC) code. The same CRC checks are performed during an outbound process and the CRC is stripped from the data prior to sending it to the Host.

The SCSI interface functions are managed by a 8-bit Motorola 68HC11 microprocessor. Low SCSI transaction overhead is maintained by automating common SCSI bus phase sequencing using a state machine in the Catalina chip.

Read/Write Channel

The Read/Write channel, in addition to the preamplifier discussed earlier, consists of three integrated circuits:

• Pulse Detector

• Data Separator

• Time base

Firmware

The drive’s firmware can be considered in two parts. The first part principally resides in the ROM for the 68HC16 background processor. This processor is responsible for:

• starting the spindle motor and maintaining precise rotational speed

• controlling track following and actuator motion during seeking

• managing background R/W activity

• power management

• monitoring the overall health of the drive.

The interface processor's control microcode resides in both ROM and RAM. The RAM portion of the microcode can be upgraded in the field with using software. Additional information regarding the RAM code can be found in Chapter 3, page

23. The interface processor firmware functions include:

• reporting drive status and error conditions to the host

• manage operating parameters for the drive

• parsing the Command Descriptor Block and checking for illegal fields

• converting the LBA to CHS and initiating read and write operations to the

background processor

• defect management

• serial port communications

Technical Reference Manual Page 7

Page 16

Chapter 1 Overview of the Drives

Since parsing/decoding of commands and execution of the Read/Write functions are handled by separate processors, command execution can be overlapped in multiple initiator or Tagged Command Queuing environments. Functions such as seek re-ordering and command coalescing can also be overlapped when the drive is operating with a host environment capable of supporting Tagged Command Queuing.

For more information on the drive’s interface implementation and command set, refer to the Ninth Generation SCSI Interface Manual.

How the Drive Operates

Functions of the Drive

This chapter describes certain operational aspects of the drive, including discussions of:

• drive operational modes

• error correction

• read error recovery

• downloadable microcode

• buffer management

Drive Operational Modes

The drive operates in the following modes:

•• Read/Write Mode occurs when data is read from or written to the disk.

•• Seek Mode (100%) occurs when the actuator is in motion.

•• Seek Mode (30%) is based on 1/3 stroke seeks with a 30% seek duty cycle.

•• Idle Mode occurs when the drive is not reading, writing, or seeking. The

motor is up to speed and the Drive Ready condition exists. The actuator is residing on the last-accessed track.

•• Standby Mode occurs when the motor is stopped and the actuator is latched in the landing zone. The drive will enter Standby mode after poweron reset if the Disable Spin jumper is installed or the DSPN bit in MODE SELECT page 0 is set. A STOP UNIT command will also place a drive into Standby Mode. The drive will spin up and go into Idle mode when a START UNIT command is issued or on a timed basis by SCSI ID if the SDLY bit is set in MODE SELECT page 0. Refer to the MODE SELECT and MODE SENSE commands in the Ninth Generation SCSI Interface Manual for additional details.

•• Spin-Up Mode occurs while the drive's spindle motor is being spun up to speed after initial power on or after exiting Standby Mode.

Technical Reference Manual Page 21

Page 30

Chapter 3 How the Drive Operates

Error Correction

The drive uses a Reed-Solomon code to perform error detection and correction. For each 512-byte block, the software error correction polynomial is capable of correcting:

• one error burst of up to 22 bits in length

• two error bursts each up to 11 bits in length

Single bursts of 11 bits or less are corrected on the fly (OTF) with no performance degradation. A larger defect up to 22 bits in length or a second defect of up to 11 bits in length is corrected using firmware within one latency period, after all retries have been exhausted.

The code has the following error detection capability:

• three error bursts each up to 11 bits in length

• a single burst of up to 51 bits in length

Read Retry Operations

The drive retries data field read operations in the following sequence if it detects an error which cannot be corrected on-the-fly. The default retry algorithm repeats eight times for a total of 128 retries or until the data is recovered.

1. Initial read

2. First retry

3. Read retry with data threshold offset +1

4. Read retry with data threshold offset -1

5. Read retry with data window offset +1

6. Read retry with data window offset -1

7. Write Spash

8. Read retry with data threshold offset +2

9. Read retry with data threshold offset -2

10. Read retry with data window offset +2

11. Read retry with data window offset -2

12. Normal read retry

13. Read retry with servo offset +8%

14. Read retry with servo offset -8%

15. Normal read retry

16. Software (2-burst) EDAC correction attempt

If retries are disabled, the drive retries the operation one time before it reports an error.

How the Drive Operates Chapter 3

Downloadable Microcode

The SCSI interface code is split into two parts which are designated as ROM or RAM code. The ROM code contains the basic SCSI operating code and code to support commands such as INQUIRY, TEST UNIT READY, REQUEST SENSE, START/STOP UNIT, etc., which may have to be responded to prior to the drive being in a ready state. The part of the interface code referred to as RAM code resides on an area of the disk which is reserved to the drive and is not directly accessible through the interface. This code is referred to as RAM code because it is read from the disk and is loaded into static RAM after power is applied to the disk, as soon as the drive is able to read from the disk.

The RAM code consists of a resident portion which is loaded after a Power On Reset. Two different versions of RAM code overlays also reside on the disk. The read look ahead code overlay is the default and is loaded into RAM during the initial power-on. If a Queue Tag message is received by the drive, the drive will execute the command and while it is in Status Phase, will read the Queuing code overlay from the disk and load it into the RAM. This operation takes about 600 milliseconds, after which the drive will complete the command by sending the status. The drive will continue to operate with Queuing code residing in RAM until the next Power On Reset.

Refer to the next section for a discussion of the buffer management implications for the different RAM codes.

The RAM code may be upgraded on the disk via the factory serial port or through the interface using the WRITE BUFFER command. Refer to the WRITE BUFFER command in the Ninth Generation SCSI Interface Manual for a discussion of the procedure.

Technical Reference Manual Page 23

Page 32

Chapter 3 How the Drive Operates

Buffer Management and Command Execution

The drive contains a 512Kbyte segmentable buffer which is dynamically configured to adapt to the particular drive configuration or operating environment.

Read Look Ahead Code

The Read Retention RAM code executes commands sequentially as they are received from the initiator(s). Commands from multiple initiators may be queued and overlapped so that the subsequent command can be parsed while the current command is being executed.

The drive's 512K byte buffer is configured as four segments. These segments allow the drive to cache sequential data from four separate areas on the disk. This can significantly improve performance in any environment in which multiple disk files are kept open simultaneously and operated upon in some interleaved fashion.

The Look-Ahead RAM code segments the 512 KB buffer into four 130,548 byte (FD

blocks) segments. The remainder of the RAM is used by the

microprocessor as a scratch pad area and for non read or write data information transfers. The buffer block size is equal to the data block size (typically 512 B) plus the 4 bytes of buffer CRC appended to each block. (refer to the Electrical Design Feature section in Chapter 1 for a description of the buffer CRC).

Buffer operations default on Power-up to Read Look Ahead enabled and Write Caching disabled. MODE SELECT page 8, byte 2, bit 0 (RCD), when set to one disables the read look-ahead cache function and bit 2 (WCE), when set to one enables write cache. In addition, MODE SELECT page 8, byte 3 contains two fields which control the retention priority for reads and writes. Refer to the Ninth Generation Disk Drive SCSI Interface Manual for additional details.

When a read command is received by the disk drive, the cache tables are searched to determine if the requested data is contained in any of the four cache segments (a cache hit). If there is no cache hit, the Least Recently Used (LRU) segment is selected and a read from disk is initiated into that segment which is now considered the Active Segment. The retention of data already transferred to the host and read look ahead in the Active Segment buffer is controlled by the state of the Read Retention Priority.

Page 24 Filepro CFP1060E/CFP1060S/CFP1060W

Page 33

How the Drive Operates Chapter 3

Read Retention On (Read Retention Priority = 0 or F):

The interface processor initiates a full segment read of 253 sectors (FD

blocks)

to the background processor. There are three different situations which would be considered a cache hit on a subsequent read.

• Full: All of the data requested is transferred from the buffer segment and

retained.

• Partial: Some but not all of the data is cached in a buffer segment. If the

cached data is in the Active Segment and the remaining data is part of the full segment read, the drive will transfer the requested data from the buffer as the background process fills it. If the cached data is in the Active Segment but the remaining data is not part of the full segment read, the drive will turn off read retention until the next Active Segment miss occurs and issues a new read (forever) to the background process. This allows the drive to adapt to long sequential reads even in read retention mode. If the data is part of an Inactive Segment, a new full segment read is initiated, making this the Active Segment.

• Potential: If none of the data is in the Active Segment, but is part of the

full segment read, the drive will transfer the data as it becomes available.

Read Retention Off (Read Retention Priority = 1): The interface processor initiates a "read forever" command to the background processor and the buffer segment is treated as a circular buffer which is back filled as sectors are transferred to the host. There are three different situations which would be considered a cache hit on a subsequent read.

• Full: All of the requested data is cached in a buffer segment. If it is the

Active Segment, the data will be transferred to the host and refilled with next sequential data. If the data in an Inactive Segment, the data is transferred to the host and retained.

• Partial: This is when some, but not all of the data is cached in a buffer

segment. If the data is in the Active Segment, data is transferred to the host as the background process fills the buffer and the "read forever" is allowed to refill the buffer. If the data in an Inactive Segment, the cached data is transferred and a new read operation is initiated for the remaining data, making this the Active Segment.

• Potential: None of the data is cached. The active segment is checked and if

the requested data is within 63 sectors of being read, the drive will allow the "read forever" operation to continue and the data is transferred to the host when it is available.

Technical Reference Manual Page 25

Page 34

Chapter 3 How the Drive Operates

Write Caching

Write Caching allows multiple write commands operating on sequential blocks to be written to the medium without losing a motor revolution between commands. Write caching is enabled by setting the WCE bit in MODE SELECT page 8 to one. The WCE bit is only valid while the Read Look Ahead code is loaded. The WCE bit is ignored when the Tagged Command Queuing code is in RAM because write coalescing will be active.

The drive will send good status and command complete following the data out phase of a cached write command. The drive will cache writes when the following conditions are met:

• Two or more write commands (Op Code 0A

or 2AH) execute consecutively

without an intervening command.

• The write commands address consecutive logical block ranges.

• At least one logical block of data has been received in the buffer from the

second write command in time to allow the medium to be written before an additional spindle revolution would be required.

• Both writes are from the same initiator.

• Neither write is a linked command.

If the drive encounters an error during a cached write operation, the drive will respond by:

If AWRE (MODE SELECT page 01

) is 0: the drive will report a CHECK

CONDITION on the next command and the response from a REQUEST SENSE will be a deferred error. (Asynchronous event notification is not supported by this drive.) Refer to the Ninth Generation SCSI Interface Manual for additional details.

If AWRE (MODE SELECT page 01

) is set to 1: the drive will attempt to

dynamically reassign the block of data and complete the operation. If the reassignment fails, the drive will continue to reassign the block until all the space in the grown defect list is filled (147 sectors, maximum).

Page 26 Filepro CFP1060E/CFP1060S/CFP1060W

Page 35

How the Drive Operates Chapter 3

Tagged Command Queuing

The drive, operating using the Tagged Command Queuing code, can queue up to 32 commands. Commands in the queue which involve seeks are re-ordered using a Scan (elevator seek methodology). Read and Write commands are coalesced (combined into a single operation to the background processor) to minimize inter processor communication overhead and reduce mechanical motion.

Seek Re-ordering

Seeks are re-ordered using the Scan or what is sometimes referred to as the elevator seek method. Seeks already in the queue are re-ordered so they can be executed sequentially on a sweep toward the inner diameter (ID) or the outer diameter (OD) of the disk. Any new seeks entering the queue ahead of the sweep is ordered for execution during the current sweep. Any new seeks entering the queue behind the current sweep are held for re-ordering during the reverse sweep. When there are no more commands in the queue ahead of the current sweep, the direction of the sweep is reversed.

Seek re-ordering is controlled by Message Code (Simple, Head of Queue or Ordered Queue) during the Message Phase. Re-ordering of seeks issued with a Simple Queue Tag message may also be restricted using the Queue Algorithm Modifier bits in MODE SELECT page 0A

. Refer to the Ninth Generation SCSI

Interface Manual for additional information on Messages and MODE SELECT page 0A

Buffer Management

The 512K byte buffer is treated by the queuing code as two 240KB buffers (F0

sectors) to maximize coalescing. Look ahead reads are performed by the drive when there are no commands in the queue awaiting execution. Look ahead reads are not performed when there are commands in the queue since another command will be waiting for execution as soon as the current command completes and because the queue affords pre-knowledge of subsequent commands instead of having to anticipate them.

Sequential read or write commands are coalesced into single commands to the background processor. On a read operation, the data associated with each queue tag is transmitted to the host as the buffer is filled by the background processor. On write operations, the drive will connect to the initiator(s), transmit the data into the buffer and disconnect; coalescing sequential data in the buffer before initiating the write to the background processor. The drive will reconnect with each of the writes, using the queue tags, completing the command after the data has been written to the disk. This operation provides the performance of write caching without the exposure of completing the command prior to writing the data to the disk.

SCSI Bus Cable

The cable and mating connector required to connect the drive to the SCSI bus are described in Chapter 5. In addition, the cable should meet the following guidelines, particularly with FAST SCSI-2 systems:

• Do not route the data cable next to the drive PCB or any other high frequency or large current switching signals. Improper drive operation can result from improper cable routing.

• Cable stubs should not exceed 0.1 meter (4 inches).

• There should be 0.3 meters (12 inches) of cable between drives.

• The total cable length should not exceed 6 meters (20 feet) and may have to

be reduced if a mixture of round and flat cable are used.

• Do not tightly bundle excess flat cable against each other since this promotes cross coupling of signals on the cable. Use spacers to maintain a minimum of

0.050 inches (1.27mm) gap between cable runs.

• Do not clamp the cable tightly against a metal chassis since this will degrade the signal. Use spacers or a non-flammable insulation material to maintain a gap between the chassis and the cable.

Spindle Synchronization

The spindle rotation of up to 35 drives may be synchronized together by daisy chaining pin 1 to pin 1 and pin 2 to pin 2 on connector J3. The spindles are synchronized using a "floating master" concept, where the drives will synchronize to the first drive to reach full speed. The synchronization tolerance is 1%.

Disabling Spin-Up at Power On - CFP1060W

A jumper in the E5 location, disables spin up on power-on for applications where spin up sequencing is necessary. Disabling spin up on application of power can also be enabled by setting the DSPN bit in MODE SELECT page 00

(Operating

Parameters). The Host must issue a START UNIT command to cause the drive to spin up. Refer to the Ninth Generation SCSI Technical Reference Manual for additional information regarding the MODE SELECT and START/STOP UNIT commands. Refer to Figure 4-6 for the location of the Disable Spin jumper E5 and the option header.

SCSI Bus Cable

• Do not route the data cable next to the drive PCB or any other high frequency or large current switching signals. Improper drive operation can result from improper cable routing.

• Cable stubs should not exceed 0.1 meter (4 inches).

• There should be 0.3 meters (12 inches) of cable between drives.

• The total cable length should not exceed 3 meters (10 feet) and may have to

be reduced if a mixture of round and flat cable are used.

• Do not tightly bundle excess flat cable against each other since this promotes cross coupling of signals on the cable. Use spacers to maintain a minimum of

0.050 inches (1.27mm) gap between cable runs.

• Do not clamp the cable tightly against a metal chassis since this will degrade the signal. Use spacers or a non-flammable insulation material to maintain a gap between the chassis and the cable.

Mixing Wide and Narrow SCSI Devices on a SCSI Bus

It may sometimes be desirable to attach Narrow SCSI devices such as tape backup devices or CDROMs to the same SCSI Host Bus Adapter being used to control Wide SCSI devices, such as the CFP1060W. Intermixing of both Wide and Narrow SCSI devices on the same bus required special considerations:

• The Narrow SCSI devices must be placed at the physical end of the bus

• The high byte of the SCSI data bus must be terminated at the transition

adapter from the 34-pair wire to the 25-pair wire. Figure 4-9 shows the interconnection.

• The cable impedance of the 34-pair wire and the 25-pair wire should be as closely matched as possible.

• The 68-pair cable with 30 AWG wire uses four wires to carry TERMPWR, which must be joined to wire 26 of the 25-pair wire, if terminator power has to be carried over the cable.

Spindle Synchronization

The spindle rotation of up to 35 drives may be synchronized together by daisy chaining pin 1 to pin 1 and pin 2 to pin 2 of each drive on connector J3 or chaining pin 6 of the 2mm option header J5. The spindles are synchronized using a "floating master" concept, where the drives will synchronize to the first drive to reach full speed. The synchronization tolerance is 1%.

Attaching Power to the Drive - CFP1060W

The drive has a 4-pin DC power connector, J4, which is part of the Unified Connector, mounted on the PCB. The recommended mating connector is AMP part number 1-480424-0 utilizing AMP pins, part number 350078-4 or equivalent.

Mounting the Drive - CFP1060W

The drive is designed to be used in applications where the unit may experience shock and vibrations at greater levels than larger and heavier disk drives will tolerate.

Eight side, or four bottom base mounting points are provided to the customer. The drive is mounted using 6-32 UNC -2B X 0.16 maximum insertion length screws. Refer to Figure 2-4 in Chapter 2 for the location of the mounting holes. The system integrator should allow ventilation to the drive to ensure reliable drive operation over the operating temperature range. The drive may be mounted in any orientation.

Interface Physical Characteristics

Electrical Description

The paragraphs which follow describe the input and output electrical characteristics of the drive.

Output Characteristics

The output drivers for Data, Parity, REQ and ACK are optionally active negation. When they are set for active negation, they have three states: asserted, negated and high impedance. The remainder of the signals have open collector (drain) outputs. The drivers maintain a high impedance state during power-on and power-off cycles. The driven signals have the following output characteristics when measured at the drive connector:

The sections which follow describe, for each of the drive models, those SCSI characteristics which vary from model to model. These characteristics include:

• Termination

• Cable requirements

• Connector requirements

• Connector Pin assignments

• Interface Timing requirements

Page 61

SCSI Physical Characteristics Chapter 5

CFP1060E (WIDE, 80-pin Single Connector Attachment [SCA])

External Terminator Power

The interface connector carries both power and ground so a separate TERMPWR interface line is not provided.

Internal Termination

This version of the drive has no on-board termination so the drive must be externally terminated. Alternative 2 active termination is recommended. Alternative 1 passive termination is not suitable for this application.

Cable Requirements

This version of the drive is designed to interface directly to a mating connector which is on a passive back plane or directly into a motherboard. The same guidelines relative to impedance, stub length and distance between stubs apply for SCSI bus signal reliability. These guidelines may not be directly translated to a back plane design so these design rules are to be viewed with respect to the intended purpose of controlling reflections and the propagation of signals down the bus. Since the characteristics for PCB signal traces are affected by trace width, proximity to ground, and trace routing, careful review of the back plane design and analysis of signal quality is highly recommended.

Connector Requirements

The drive's connector will mate with a AMP Champ 2-557103-1 vertical receptacle or the AMP Champ 2-557101-1 right angle receptacle.

Single Connector Attachment (SCA) Signal Definitions

Power

Four +12 Volt signals provide the +12 volt power to the drive. The current return for the +12 volt power is through the +12 Volt Ground signals. The maximum current that can be provided to the drive through the +12 Volt signal pins is 3 Amperes. The supply current and return current must be distributed as evenly as possible among the pins. The maximum current is while the drive motor is starting.

Three +5 Volt signal pins provide +5 volt power to the drive. The current return for the +5 volt power is through the +5 Volt Ground pins. It is expected that the +5 Volt Ground will also establish the digital logic ground for the drive. The maximum current that can be provided to the drive through the +5 Volt signal pins is 2 Amperes. The supply current and return current must be distributed as evenly as possible among the pins.

These specifications refer to the connector's characteristics. Refer to Chapter 2 for the drive's power requirements.

Spindle Sync

The spindle rotation of up to 35 drives may be synchronized together by daisy chaining pin 1 to pin 1 and pin 2 to pin 2 of each drive on connector J3.

External Terminator Power

Power to the on-board terminators is provided by the higher of the voltage supplied at Pin #17, 18, 51, & 52, J2 or the voltage level at the 5 Volt power input to the drive minus one diode drop. The diode prevents back flow of current to the drive. Termination Power to external terminators can be supplied by the drive through Pin #17, 18, 51, & 52, J2. The TERMPWR line can be disconnected from the drive by removing Jumper E8. Table 5-11 describes the electrical characteristics of the TERMPWR line when it is used to supply power to an external terminator.

SCSI Physical Characteristics Chapter 6

Tracks Per Zone: Defines the number of tracks per zone to use in dividing the capacity of the drive for the purpose of allocating alternate sectors. A value of zero means that one zone is defined for the entire drive.

Alternate Sectors Per Zone: Defines the number of spare sectors per zone the drive reserves for defect handling. Not supported. Must be set to zero.

Alternate Tracks Per Logical Unit: Not supported. Must be set to zero.

Sectors Per Track: Defines the number of physical sectors per track. The

number includes the one alternate sector per track the drive allocates. The value reported for the number of sectors per track is dependent on the active notch value.

Data Bytes Per Physical Sector: Defines the number of data bytes per physical sector.

Interleave: Defines the interleave value used by the drive.

Track Skew Factor: Defines the number of physical sectors between the last

logical block of one track, and the first logical block on the next sequential track of the same cylinder.

Cylinder Skew Factor: Specifies the number of physical sectors between the last logical block of one cylinder and the first logical block on the next sequential cylinder.

SSEC (Soft Sector Format): Set to zero to indicate the drive does not support a soft sector format.

HSEC (Hard Sector Format): Set to one to indicate the drive supports a hard sector format.

RMB (Removable Media): Set to zero to indicate the drive does not have removable media.

SURF (Surface Format): The SURF bit is set to zero, meaning the drive allocates progressive addresses to all logical blocks within a cylinder prior to allocating addresses on the next cylinder.

ND (Notched Drive): If set to zero, the drive is not notched and all other parameters in this page are returned as zeros. If set to one, the drive is notched and this page defines the starting and ending boundaries for each active notch. This parameter is always set to one.

LPN (Logical or Physical Notch): When set to zero, indicates the notch boundaries are physical addresses (i.e., cylinder and head). An LPN bit of one is not supported.

The Maximum Number of Notches field indicates the maximum number of notches supported by the drive.

The Active Notch field indicates which notch is being referred to by this and subsequent MODE SELECT and MODE SENSE commands, until changed by a later MODE SELECT command. Active notches are numbered beginning from one up to the maximum number of notches.

The Starting Boundary field indicates the beginning of the active notch; the three most significant bytes represent the cylinder number and the least significant byte represents the head number.

The Ending Boundary field indicates the ending of the active notch; the three most significant bytes represent the cylinder and the least significant byte represents the head number.

The Pages Notched field is a bit map of the MODE SELECT page codes which indicates the pages containing parameters that are changed for different notches. The most significant bit of this field corresponds to page code 3F and the least significant bit represents page code 0. If a bit is a one, the corresponding MODE SELECT page contains parameters that are changed for different notches. If a bit is a zero, the corresponding MODE SELECT page parameters are constant for all notches.
