NOTES
1. Jumpers for JP1, 2, and 3 should not be selected concurrently.
2. JP1 is for Master, JP2 is for Slave, JP3 is for Cable Selection
mode.
3. To enable Cable Selection mode, the JP3 jumper must be installed.
In the Cable Selection mode, the drive address is determined as
follows:
- When CSEL signal (pin 28) is grounded or at a low level, the
drive address is 0 (master).
- When CSEL signal is open or at high level, the drive address
is 1 (slave).
4. Position JP4 is not used.
5. A jumper for JP5 is used to disable write-cache.
6. A jumper for JP6 is used to disable auto-reallocation.
7. A jumper for JP7 has a meaning when the model name is DPEA-30540.
A jumper for JP7 is used to select 541MB i.e. when the jumper is
removed, DPEA-30540 is set to 518MB. This jumper has no meaning
for DPEA-30810 and DPEA-31080.

The drive will operate in all axis (6 directions).
Mounting Orientation
--------------------
The drive operates in all axes (6 directions). The drive operates
within the specified error rates when tilted 5 degrees from these
positions.
Performance and error rate stay within specification limits even if
the drive is operated in other orientations from which it was
formatted. Thus a drive formatted in the horizontal orientation
operates in the vertical position without any degradation, and vice
versa.
The recommended mounting screw torque is 3 0.5 [Kgf.cm]. The
recommended mounting screw depth is 3.5 0.5 [mm] for bottom and 5.0
0.5 [mm] for horizontal mounting.
The system is responsible for mounting the drive securely enough to
prevent excessive motion or vibration of the drive at seek operation
or spindle rotation, using appropriate screws or equivalent mounting
hardware.
The vibration test and the shock test are to be conducted with the
drive mounted to the table using four bottom screws.
Identification Labels
---------------------
The following labels are affixed to every drive.
1. A label placed on the top of the HDA contains the statement "Made
by IBM" or equivalent, Part number, and MLC number.
2. A bar code label placed on the disk drive is based on user
request. The location is to be designated in the drawing.
3. Labels containing the vendor's name, disk drive model number,
serial number, place of manufacture and UL/CSA logos.
Except for the bar code, the labels may be integrated.
Cabling
-------
The maximum cable length from the host system to the drive, plus the
circuit pattern length in the host system, cannot exceed 46 [cm].
Interface Connector
-------------------
The DC 4-pin connector is designed to mate with AMP 1-480424-0 or
equivalent.
The AT signal connector is designed to mate with 3M 3417-7000 or
equivalent.
Interface Logic Signal Levels
-----------------------------
The interface logic signal have the following electrical
specifications:
Inputs: Input High Voltage 2.0 V min.
Input Low Voltage 0.8 V max.
Outputs: Output High Voltage 2.4 V min.
Output Low Voltage 0.5 V max.

Physical Format
---------------
On manufacturing process, all sectors of hard disk drive are tested
for the magnetical performance, so that only acceptable sectors are
used.
In data area, accepted sectors are numbered sequentially for user
data sectors.
This mapping information is maintained at firmware level, and data
block addressed by logical cylinder, head and sector is translated
into physical location on disk(s) automatically. This operation is
invisible from application level.
Low level format is NOT ALLOWED after normal manufacturing in
factory.
Error Rate ---------- - Probability of not recovering data .... 1 in 10(13) bits read
- ECC implementation 128-bit Non-interleave Reed Solomon Code operating 10-bit symbol is used to cover the data fields. On-The-Fly correction covers up to four symbols of error in one sector.
Error Register -------------- +-----------------------------------+ | Error Register | +---+---+---+----+--+----+-----+----+ | 7 | 6 | 5 | 4 |3 | 2 | 1 | 0 | |BBK|UNC| 0 |IDNF|0 |ABRT|TK0NF|AMNF| +---+---+---+----+--+----+-----+----+
This register contains status from the last command executed by the
drive, or a diagnostic code.
At the completion of any command except Execute Drive Diagnostics,
the contents of this register are valid.
Following a power on, a reset, or completion of an Execute Drive
Diagnostic command, this register contains a diagnostic code.
Bit Definitions
BBK Bad Block. BBK = 1 indicates a bad block mark was detected
in the requested sector's ID field.
UNC Uncorrectable Data Error. UNC = 1 indicates an
uncorrectable data error has been encountered.
IDNF(IDN) ID Not Found. IDN = 1 indicates the requested sector's ID
field could not be found.
ABRT(ABT) Aborted Command. ABT = 1 indicates the requested command
has been aupported to a drive status error or an invalid
parameter in an output register.
TK0NF Track 0 Not Found. T0N = 1 indicates track 0 was not found
(T0N) during a Recalibrate command.
AMNF(AMN) Address Mark Not Found. AMN = 1 indicates the data address
mark has not been found after finding the correct ID field
for the requested sector.
Read Look-Ahead --------------- The drive keeps the buffers into 32 Kbytes as read/write cache. - Least Frequent Used buffer is discareded to save the newly requested data.
Write Cache
-----------
When the write cache is enabled, write cache uses a dedicated 32
Kbytes buffer. (The write cache is enabled by checking jumper setting
at power-on-reset period. And if the jumper setting is for enabling
write cache, this can be enabled or disabled by sending set features
commands.)
- If the previous command is WRITE, and the block requested is consecutive to the previous, the drive will return "COMPLETE" after all data is received in the drive buffer.
- Soft reset is recommended to check the actual data writing to media, i.e., soft reset is processed after the previous write command (with cache) completes the actual writing to media.
- Certain power down during Write Cache operation may result in Non- recoverable error later. Write to the broken sector will recover this sector.
- Automatic reallocation will be invoked at the failing sector if a non-recoverable error occurs and the write will be completed normally.
- If the drive runs out of spares for reallocation, write cache and reallocation will be turned off.
- If the drive is unable to complete a cached write and/or reallocation after good status has been returned, the drive will not process any commands including a soft reset. This condition will be cleared at power on, or a hardware reset.
Warranty
--------
The warranty will be covered by contracts.
Landing Zone and Lock
---------------------
A landing zone on the disk, not the data area of the disk, is
provided to protect the disk data during shipping, movement, or
storage. After power down, a head locking mechanism secures the heads
in this zone.
