3.0 Fixed disk subsystem description
3.1 Control electronics
The drive is electronically controlled by a microprocessor, logic modules, digital/analogue modules, and
various drivers and receivers. The control electronics perform the following major functions:
! Perform self-checkout (diagnostics).
! Conduct a power-up sequence and calibrate the servo.
! Monitor various timers for head settling, servo failure, etc.
! Analyze servo signals to provide closed loop control. These include position error signal and
estimated velocity.
! Control the voice coil motor driver to align the actuator onto a desired position.
! Monitor the actuator position and determine the target track for a seek operation.
! Constantly monitor error conditions of the servo and take corresponding action if an error occurs.
! Control starting, stopping, and rotating speed of the spindle.
! Control and interpret all interface signals between the host controller and the drive.
! Control read write accessing of the disk media, including defect management and error recovery.
3.2 Head disk assembly
The head disk assembly (HDA) is assembled in a clean room environment and contains disks, a spindle
motor, actuator assembly, and voice coil motor. Air is constantly circulated and filtered when the drive is
operational. Venting of the HDA is accomplished via a breather filter.
The spindle is driven directly by a brushless, sensorless DC drive motor. Dynamic braking is used to stop
the spindle quickly.
3.3 Actuator
The read/write heads are mounted in the actuator. The actuator is a swing-arm assembly driven by a
voice coil motor. A closed-loop positioning servo controls the movement of the actuator. An embedded
servo pattern supplies feedback to the positioning servo to keep the read/write heads centered over the
desired track.
The actuator assembly is balanced to allow vertical or horizontal mounting without adjustment.
When the drive is powered off, the actuator automatically moves the head to aparking position outside of
the disk, where the actuator is locked.

4.5 Performance characteristics
The performance of a drive is characterized by the following parameters:
! Command overhead
! Mechanical head positioning
- Seek time
- Latency
! Data transfer speed
! Buffering operation (read ahead/write cache)
NOTE: All the above parameters contribute to drive performance. There are other parameters that contribute to the performance of the actual system. This specification tries to define the bare drive characteristics, not the system throughput, which depends on the system and the application.
4.5.1 Command overhead
Command overhead is defined as the time required:
! from last byte of command phase
! to the first byte of data phase
! excluding
- Physical seek time
- Latency time
- Initiator delay with reconnections

“Typical” and “Max” are given throughout the performance specification by:
Typical Average of the drive population tested at nominal environmental and voltage conditions.
Max Maximum value measured on any one drive over the full range of the environmental and
voltage conditions. (See Section 7.3, "Environment" on page 30 and Section 7.5,
"DC power requirements" on page 32 for ranges.)
The seek time is measured from the start of the actuator's motion to the start of a reliable read or write
operation. “Reliable read or write” implies that error correction or recovery is not used to correct arrival
problems. The average seek time is measured as the weighted average of all possible seek combinations.

! Sustained disk-buffer transfer rate is defined by considering head/cylinder change time. This gives a
local average data transfer rate. It is derived by
(Sustained Transfer Rate) = A/(B +C)
A = (Number of data sectors per cylinder) * 512
B = Average track change time
C = (# of Surface) * (One revolution time)
! Buffer-host transfer rate defines the maximum data transfer rate on SCSI Bus. It also depends on the
speed of the host.
4.5.6 Buffering operation (read ahead/write cache)
This hard disk drive has a buffer for read ahead and write caching. For details, refer to the SCSI interface

5.0 Data integrity
The drive retains recorded information under all non-write operations.
No more than one sector will be lost by power down during write operation while write cache is disabled.
If power down occurs before completion of data transfer from write cache to disk while write cache is
enabled, the data remaining in write cache will be lost. To prevent this data loss at power off, the following
action is recommended:
! Confirm successful completion of SYNCHRONIZE CACHE (35h) command.
5.1 Equipment status
Equipment status is available to the host system any time the drive is not ready to read, write, or seek.
This status normally exists at power-on time and will be maintained until the following conditions are
satisfied:
! Access recalibration/tuning is complete.
! Spindle speed meets requirements for reliable operations.
! Self-check of drive is complete.
Appropriate error status is made available to the host system if any of the following condition occurs after
the drive has become ready:
! Spindle speed goes outside of requirements for reliable operation.
! “Write fault” is detected.
5.2 Error recovery procedure
Errors occurring with the drive are handled by the error recovery procedure.
Errors that are uncorrectable after application of the error recovery procedures are reported to the host
system as non-recoverable errors.

6.0 Physical format
Media defects are remapped to the next available sector during the Format Process in manufacturing. The
mapping from LBA to the physical locations is calculated by an internally maintained table.
6.1 Shipped format (P-List)
! Data areas are optimally used
! No extra sector is wasted as a spare throughout user data areas
! All pushes generated by defects are absorbed by spare tracks of the inner zone
Figure 17. P-List physical format
NOTE: Defects are skipped without any constraint, such as track or cylinder boundary. The calculation
from LBA to physical is done automatically by internal table.
6.2 Reassigned format (G-List)
! G-List is prepared for 1078 LBAs
! Multiple reassignment of the same LBA does not increase G-List entry
! A cylinder for spare sectors is prepared every 512 physical cylinders
NOTE: G-List entries are part of the normal maintenance work of hard disk drives. G-List entries are
possible during early drive usage and are caused mainly by handling.

NOTE*1: HVD is not supported.
NOTE: SCA-2 connector is not mechanically compatible with the 68 pin “P” connector as defined in the
ANSI SCSI standard. The connector is intended for direct back plane attachment and is not intended to
be cable attached to the bus.
Eight-bit devices which connect to the SCA-2 connector should have the following signals inactive (high):
-DB(8), -DB(9), -DB(10), -DB(11), -DB(12), -DB(13), -DB(14), -DB(15), -DB(P1). All other signals shall be
connected as defined.
Ultrastar 146Z10 hard disk drive specifications

7.1.3 SCSI cable
Refer to ANSI SPI-4.
7.1.4 SCSI bus terminator
Onboard SCSI active termination feature is not supported. The using system is responsible for making
sure that all required signals are terminated at both ends of the bus cable.
Terminator power
Termination power can be provided by the drive 5V supply through the current limiter and Schottky diode.
This function can be selected by jumper.
The 80-pin SCA-2 models do not support SCSI bus termination power.
7.1.5 Hot plug/unplug
The term 'Hot Plug' refers to the action of mechanically engaging a device to the power and/or bus when
other devices may be active on the same bus. A comprehensive classification of the state of the SCSI bus
during this event is located in the SCSI-3 Parallel Interface Standard.
While every effort was made to design the drive not to influence the SCSI bus during these events, it is the
responsibility of the system to insure voltage regulation and conformance to operational and nonoperational shock limits. During Hot Plug events the non-operational shock levels should not be exceeded. The operational shock levels of adjacent drives should also not be exceeded. The recommended
procedure is to prohibit write operations to adjacent drives during Hot Plug and Hot Unplug actions.
During Hot Unplug the operational shock limit specifications should not be exceeded. If this cannot be
guaranteed, the drive should be issued a SCSI Stop Unit command that is allowed to complete before
unplugging. The basic requirement is that while the drive is operational or spinning down the operational
shock limits are in effect. When the drive has completely stopped, the non-operational shock limits are in
effect. The recommended procedure is to allow the unplugged drive to rest in the drive bay for a minimum
of 15 seconds and then complete the removal. During Hot Plug or Unplug events the power supply ripple
on adjacent operational drives should not be outside the ±5 % regulation tolerance. It is recommended
that the system have current limiter for in-rush current as described in ANSI SPI-4.
Hot plugging/unplugging the 68-pin model drive to the power supply or to SCSI bus connector is not
allowed since provisions are not available to determine which electrical contact is made first. It may cause
glitches on the system SCSI bus and/or electrical over stress that may result in permanent damage of
electrical components of the drive. It is the responsibility of the system to protect the drive from these
situations when the 68-pin model is connected to the power supply or to SCSI bus.
7.1.6 SCSI bus electrical characteristics
Refer to ANSI SPI-4 for bus electrical characteristics.
NOTE: If the drive is connected to an HVD bus, the drive I/O will be permanently damaged.

Figure 34. Power supply generated ripple at drive power connector
During drive start up and seeking 12-volt ripple is generated by the drive (referred to as dynamic loading).
If the power of several drives is daisy-chained, the power supply ripple plus other drive dynamic loading
must remain within the regulation tolerance of ±5%. A common supply with separate power leads to each
drive is a more desirable method of power distribution.
To prevent external electrical noise from interfering with the drive's performance, the drive must be held by
four screws in a user system frame which has no electrical level difference at the four screws position, and
has less than ±300 milivolts peak to peak level difference to the drive power connector ground.

7.6 Reliability
7.6.1 Start/stop cycles
The drive is designed to withstand a minimum of 50,000 start/stop cycles at ambient environment.
The drive is designed to withstand a minimum of 10,000 start/stop cycles at operating environment
conditions specified on page 30.
7.6.2 Data reliability
The probability of uncorrectable data error rate is 10 in 1x1016 bits read.
The following ECC on the fly correction is implemented:
! 1 Symbol : 8 bits
! 3 Interleave
! 15 Symbols, 5 symbols per each interleave, for on the fly correction. This implementation always
recovers 5 random burst errors and a 113 bit continuous burst error.
7.6.3 Seek/ID miscompare errors
A non-recoverable seek/ID miscompare error is defined as a seek operation that cannot be recovered by
the error recovery procedure of the drive. The drive reports sense key 04 and sense code 02 for this
error.
No drive has more than one non-recoverable seek/ID miscompare error per 100 million seek operations
(1 in 1x10
8
) when operated at the full range of voltage and environmental conditions.
7.6.4 Equipment errors
A recoverable equipment error is any error other than a seek/ID mis-compare error or read error that is
detected and corrected by the drive error recovery procedure. Examples are Write Fault, Drive Not Ready
and internal drive errors.
No drive has more than one recoverable equipment error per 10
when operated at the full range of voltage and environmental conditions.
Non-recoverable equipment errors indicate a defective drive.

read, 108 write or 10 6 seek operations
7.6.5 Failure prediction (PFA/S.M.A.R.T.)
The drive supports Informational Exceptions Control Page (1C) defined in the SCSI-3 Parallel Interface
Standard. The function enables the drive to report sense codes of FAILURE PREDICTION THRESHOLD
EXCEEDED to the host system. The Mode page 1C specifies enable/disable, reporting method, and
report count.
If the drive exceeds the failure prediction threshold, the drive returns Check Condition on any command.
Per the specified reporting method in Mode Page 1C, 0/5D/00, 1/5D/00, or 6/5D/00 as sense key/code/
qualifier is then sent to the host as a response of Request Sense command.
As the default the function is enabled but no reporting of informational exception condition is made.
The details are described in Section 8.8.13, "Mode Page 1C (Informational Exceptions Control)" on
page 111.
7.6.6 Preventive maintenance

Figure 49. SCSI Control Byte
VU VU stands for Vendor Unique.
FLAG The Flag bit specifies which message the drive shall return to the initiator if the link bit is one
and the command completes without any error. If Link is zero, Flag must also be zero. If Link is
one and the command terminates successfully, the drive will send either the LINKED
COMMAND COMPLETE message (FLAG=0) or the LINKED COMMAND COMPLETE WITH
FLAG message (FLAG=1). Typically this bit is used to cause an interrupt in the initiator between linked commands.
LINK This bit is set to one to indicate that the initiator desires an automatic link to the next command
upon successful completion of the current command. Upon successful completion of the
command, the drive will return INTERMEDIATE GOOD status and then send one of the two
messages defined under Flag above.
Upon unsuccessful completion of the command, the drive will return CHECK CONDITION
status or RESERVATION CONFLICT status and then send the COMMAND COMPLETE
message. No further commands in the chain are executed.

Note: The drive manages two internal defect lists and one external. The primary defect list (“P”List) is
created at time of manufacture. The grown defect list (G-List) is built after manufacture by the
Initiators use of the REASSIGN BLOCK command and the Automatic Reallocate functions. The data
defect list (D-List) is an external list. It is supplied by the initiator in the DATA OUT phase of the
FORMAT UNIT command.

! Defect List Format specifies the format of the defect descriptor transferred to the drive when
FmtData bit is set to one. The drive supports three defect descriptor formats for the Format Unit
command as following:
Format Description
000b Block format
100b Bytes From Index format
101b Physical Sector format
If the FmtData bit is set to zero, this field must also be zero. Otherwise the command will complete
with a CHECK CONDITION with a sense key of ILLEGAL REQUEST and an additional sense code of
INVALID FIELD in CDB.
! Interleave Factor may be zero or one, either of which specifies an interleave of 1:1. Other Interleave
Factors are ignored because of the extensive buffering implemented in the drive.

Figure 51. Format of Defect List Header
The drive has a limited implementation of the Format Option bits located in Bits 2 through 7 of Byte 1 of
the Defect List Header (See Figure 48). If the initiator attempts to select any function not implemented by
the drive, the drive terminates the command with CHECK CONDITION Status. The sense key is set to
ILLEGAL REQUEST and the additional sense code is set to INVALID FIELD IN PARAMETER LIST.
! FOV (Format Options Valid) bit of zero causes the drive to verify that the setting for the DPRY
(Disable Primary), DCRT (Disable Certification), STPF (Stop Format), IP (Initialize Pattern), and DSP
(Disable Saving Parameters) bits are zero. If any of these bits are not zero, the drive terminates the
command with CHECK CONDITION Status. The sense key is set to ILLEGAL REQUEST and the
additional sense code is set to INVALID FIELD IN PARAMETER LIST.
Note: When FOV bit is one, three combinations of the DPRY, DCRT, STPF, IP and DSP bits are
allowed. Any other combinations return a Check Condition Status With a sense key of ILLEGAL
REQUEST and an additional sense code of INVALID FIELD IN PARAMETER List. The supported
combination is
DPRY=0 DCRT=1 STPF=1 IP=0 DSP=0

! DPRY (Disable Primary) bit set to zero indicates that the drive does not use portions of the medium
identified as defective in the primary defect P-LIST for Initiator addressable logical blocks. If the drive
cannot locate the P-List or it cannot determine whether a P-List exists, the drive terminates the
FORMAT UNIT command as described for STPF=1. A DPRY bit of one indicates that the drive does
not use the P-list to identify defective areas of the medium. The P-list is not deleted.
! DCRT (Disable Certification) bit of ZERO indicates that the drive performs a medium certification
operation and generates a Certification List (CList) and the drive adds the Clist to the G-List. A DCRT
bit of one indicates that the drive does not generate a CList (Certification List) nor perform a certification process while executing the FORMAT UNIT Command.
Note: Since the DCRT bit is part of the DATA OUT phase that follows the format command, the
FCERT bit in Mode Page 0 is provided to control certification when the format command is issued with
no DATA OUT phase. If a format command is issued with a DATA OUT phase then FCERT is
ignored.
! STPF (Stop Format) bit must be set to one. If one or both of the following conditions occurs, the drive
terminates the Format Unit command with CHECK CONDITION Status. The sense key is set to
MEDIUM ERROR and the additional sense code is set to either DEFECT LIST NOT FOUND if the
first condition occurred or it is set to DEFECT LIST ERROR if the second condition occurred.

1. The drive cannot locate a required defect list nor determine that the list exists.
2. The drive encounters an unrecoverable error while accessing a required defect list.
! IP (Initialization Pattern) bit must be set to zero. The drive initializes all data with zeros.
! DSP (Disable Saving Parameters) bit must be set to zero. The drive saves all the MODE SELECT
savable parameters during the format operation.
! Immed (Immediate) bit set to zero requests that status be returned at the end of the format operation.
An immediate bit set to one requests that status be returned immediately. GOOD Status is returned
following the CDB validation and transfer of data in the DATA OUT phase. If the immediate format
operation terminates in error, Deferred Error Sense data is generated. With the immediate bit set to
one, the Link bit must be set to zero.
8.4.2 Defect descriptor
The Defect List Length field specifies the total length in bytes of the defect descriptors that follow. The
drive has an implementation limitation for the number of defect descriptors. The number of defect
descriptors shall be less than 128. The defect list length must be equal to four times the number of defect
descriptors to follow for the BLOCK format or eight times the number of defect descriptors to follow for the
BYTES FROM INDEX and PHYSICAL SECTOR format. Otherwise the command is terminated with
CHECK CONDITION STATUS, the sense key is set to ILLEGAL REQUEST, and the additional sense
code is set to INVALID FIELD In PARAMETER LIST. The defect descriptors must specify the defect
based on the current Format Device parameters reported by the MODE SENSE command.
The drive supports three Defect List formats.
8.4.2.1 Block format

sectors is given by their LBA.

! Allocation Length specifies the number of bytes that the initiator has allocated for INQUIRY data to
be returned. An allocation length of zero implies that no data returned. The drive will terminate the
DATA IN phase when all available INQUIRY data has been transferred or when allocation length
bytes have been transferred, whichever is less.
If an INQUIRY command is received from an initiator with a pending unit attention condition (before the
drive reports CHECK CONDITION status), the drive processes the INQUIRY command. The unit attention
condition is not cleared by this action.

! Log Parameters
Each log parameter begins with a four-byte parameter header followed by one or more bytes of parameter value data.
The Parameter Code field identifies which log parameter is being transferred for that log page.
The Parameter Control field, the 3rd byte of each parameter header, contains several fields:
• DU (Disable Update) bit is set to 0 which indicates that the drive updates the log parameter value
to reflect events that should be noted by that parameter.
• DS (Disable Save) bit is set to 1 to indicate the parameter is non-savable and is set to 0 to
indicate that the parameter is savable.
• TSD (Drive Save Disable) bit is set to zero which indicates that the drive provides a drive defined
method for saving log parameters.
• ETC (Enable Threshold Comparison) bit is set to 0 which indicates the drive does not perform
comparisons between cumulative and any threshold values.
• TMC (Threshold Met Criteria) field is not valid because this drive does not perform threshold
comparisons. This field is set to 0.
• LBIN (List Binary) bit is only valid if the LP is 1. If the LP bit is 1 and the LBIN bit is 0, the list para-
meter is a string of ASCII graphic code (20h - 7Eh). If the LP bit is 1 and the LBIN bit is 1, the list
parameter is a list of binary information.

Command Code = 1Ah0
Allocation Length4
Figure 80. MODE SENSE (1A)
The MODE SENSE (1A) command provides a means for the drive to report various device parameters to
the initiator. It is the complement to the MODE SELECT command.
If the DBD (Disable Block Descriptor) bit is zero, the drive will return the Block Descriptor. If the DBD bit is
set to 1, the drive will not return the Block Descriptor.
Allocation Length indicates the maximum number of bytes which the initiator has set aside for the DATA
IN phase. A value of zero is not considered an error. If the allocation length is smaller than the amount
available, that portion of the data up to the allocation length will be sent. This may result in only a portion
of a multi-byte field being sent.
Page Control Field: PCF (Page Control Field) defines the type of Page Parameter values to be returned.

0 0 Report current values. The drive returns the current values under which the logical unit is pre-
sently configured for the page code specified. The current values returned are
1. The parameters set in the last successful MODE SELECT command.
2. The saved values if a MODE SELECT command has not been executed since the last
power-on, hard RESET condition, or TARGET RESET message.
Note: The drive will not process the Mode Select command until the completion of spin-up.
Therefore the initiator cannot modify the current values prior to the saved values being read in.
0 1 Report changeable value. The drive returns the changeable values for the page code specified.
The page requested is returned containing information that indicates which fields are changeable.
All bits of parameters that are changeable shall be set to one. Parameters that are defined by the
drive shall be set to zero. If any part of a field is changeable, all bits in that field shall be set to
one.
Note: For a value field such as the buffer ratios of page 2 the bit field will not indicate the range of
supported values but rather that the field is supported.
1 0 Report default value. The drive returns the default values for the page code specified. The para-
meters not supported by the drive are set to zero.
Ultrastar 146Z10 hard disk drive specifications

1 1 Report saved value. The drive returns the saved value for the page code specified. Saved
values are one of following:
! the values saved as a result of MODE SELECT command
! identical to the default values
! zero when the parameters are not supported
The Page Length byte value of each page returned by the drive indicates up to which fields are
supported on that page.

! Mode Data Length. When using the MODE SENSE command, the mode data length field specifies
the length in bytes of the following data that is available to be transferred. The mode data length does
not include the length byte itself. When using the MODE SELECT command, this field is reserved.
! Medium Type field is always set to zero in the drive (Default Medium Type).
! WP. When used with the MODE SELECT command, the Write Protect (WP) bit is reserved.
When used with the MODE SENSE command, a Write Protect (WP) bit of zero indicates that the
medium is write enabled.
! Block Descriptor Length specifies the length in bytes of the block descriptors.
When used with the MODE SELECT command, zero or eight is supported by the drive.
When used with the MODE SENSE command, the drive returns eight to indicate that only a single
block descriptor is available.

Figure 84. MODE Parameter Block Descriptor
The Block descriptor provides formatting information about the Number of Blocks (user addressable) to
format at the specified Block Length.
! Number of Blocks
When used with the MODE SELECT command, the Number of Blocks field must be
- Zero to indicate not to change available blocks
- 0xFFFFFFFF to indicate all available blocks
- The exact number of blocks in the data area of the drive, which can be obtained with the MODE
SENSE
- The number of blocks less than exact one, in order to CLIP the number of blocks
Any other value is invalid and causes the command to fail with CHECK CONDITION status.
When used with the MODE SENSE command, the field contain exact number of blocks.
! Block Length
When used with the MODE SELECT command, the Block length field must contain the value from
512 to 528 (2 bytes step) or zero. Otherwise the drive will terminate the command with CHECK
CONDITION status.
A Format Unit command is required to cause these parameters to become current only if the block
length parameter is different from the current block length.
When used with the MODE SENSE command, the field is dependent on how the media is currently
formatted.

Mode Parameters
Each mode page contains a page code, a page length, and a set of mode parameters.
When using the MODE SENSE command, a Parameter Savable (PS) bit of one indicates that the mode
page can be saved by the drive in the reserved area of the drive. A PS bit of zero indicates that the supported parameters cannot be saved. When using the MODE SELECT command, the PS bit is reserved
(zero).
The drive supports the following mode page code:

The page length field specifies the length in bytes of the mode parameters that follow. If the initiator does
not set this value to the value that is returned for the page by the MODE SENSE command, the drive will
terminate the command with CHECK CONDITION status.
