01
|
No
Index Or Sector
Was Found |
Low-level format drive. If
diagnostics run error-free, drive is
serviceable. |
02
|
Seek Incomplete |
Time required to
physically move head/arm
assembly or switch heads exceeds specified
limits. Probable hardware
failure. |
03
|
Write Fault. |
Track position
or write circuit fault detected during write
operation. Not
always a hardware failure. A physical jolt
to drive during write operation could cause
this. Isolated occurrence
does not mean a hardware failure. |
04
|
Drive Not Ready |
Spindle motor speed out of
spec or device requires a motor start command,
command not issued. Power-off-on and
retest drive. |
09
|
Track Following
Error |
Actuator position cannot
be maintained
over given track. Probable hardware
failure. |
0C
|
Write Error |
Failure occurred during
write operation (probably
with Verify on) and auto-reallocation of sector
failed or not supported
on this type drive. Low-level format or sector
re-assigned.
If diagnostics run error-free, drive is
serviceable. |
10
|
ID CRC |
Read error detected in ID
field of sector during a read or write
operation. Low-level format drive.
If diagnostics run error free the fixed disk is
serviceable. |
11
|
Unrecoverable Read Error |
Occurred in the data field
of the sector that
could not be corrected. Sector should be
re-written, reassigned,
or low-level format done. If diagnostics run
error-free, drive is serviceable. |
14
|
No Record Found |
SCSI device can't find
requested
record. Low-level format drive,
retest. If no errors
occur, drive is serviceable. |
15
|
Seek Positioning
Error |
Positioning of head/arm
assembly
to a new location failed. Probable
hardware failure. |
16
|
Data
Synchronization
Mark Error |
Sync byte at data field
cannot
be detected. Low-level format drive.
If diagnostics run error-free, the disk is
serviceable. |
17
|
Recovered Read
Data
without ECC |
ECC check bytes calculated
from data read during first read
operation doesn't match ECC check
bytes appended to data field and did match on
subsequent read operation. Possible
minor media defect. Rewrite, re-assign sector,
or low level format drive and re-run
diagnostics. If no error
is detected, disk is serviceable. |
18
|
Recovered Read
Data With ECC |
ECC check bytes calculated
from data read during first read
doesn't match ECC check bytes appended
to data field, ECC correction applied on
subsequent read.
Possible minor media defect. Rewrite
re-assign sector or low level
format drive and re-run diagnostics. If no
error, fixed
disk is serviceable. |
19
|
Defect List Error |
Data error detected while
reading manufacturing defect list or while
reading or writing grown defect
list. Low-level format, ignore grown
defect list, retest drive. If no errors,
drive is serviceable. |
1A
|
Parameter List
Length Error |
Command operation code
received
by device invalid. Probable software problem. |
1B
|
Synchronous Data
Transfer Error |
Error during data
transmission.
Check cable connections, cable termination,
excessive cable length,
and retest. |
1D
|
Compare Error |
Data read from media
doesn't
match data written to media on a Write with
Verify command.
Probable hardware problem. |
20
|
Invalid Command
Operation Code |
Command operation code
received
by device is not supported. |
21
|
Illegal
Logical
Block Address |
Logical block address
requested outside range supported by
device. Probable software problem. |
24
|
Illegal Field
In The CDB |
Device detects unexpected
values
in any field of CDB (Command Descriptor Block)
Probable software problem. |
25
|
Illegal LUN |
LUN field in CDB not
supported.
Probable software problem. |
26
|
Illegal Field In
The
Parameters List |
Device detects unexpected
values in any field of parameter
list. Probable software problem. |
28
|
Removable Medium
Changed |
(Not applicable for fixed
disk drives.) |
29
|
Power-On Reset
or
Bus Device Reset |
POR / bus device reset
sense
code indicates device (drive) reset. Reset
due to software issued commands or defective
hardware. |
2A
|
Mode Select
Parameters Changed |
Not a hardware failure.
Could be software or diagnostic code problems. |
31
|
Media Format
Corrupted |
Media format appears
corrupted
or interrupted (power down, reset, etc.) prior
to completion of Format
Unit command. Format Unit command should be
re-issued and must
complete successfully for this error condition
to be removed. |
32
|
No Defect Spare
Location Available |
Reassign Block Command
cannot
successfully complete because all available
spare sectors used. Low-level format, ignore
grown defect list, and retest drive. If no
errors, drive is serviceable. |
3F
|
Operating
Condition
On The Device Has
Been Changed |
This is probably a
software error. |
40
|
Component Failure |
Drive self-test
diagnostics detected failure
(Hardware) in device. |
43
|
Message Reject
Error |
Inappropriate or
unexpected Message
Reject received from SCSI Adapter/A or SCSI
Adapter/A rejects
a message twice. |
44
|
Internal
Controller Error |
Internal microprocessor
detects
incorrect status or receives an illegal request
from device electronics. Hardware failure. |
45
|
Select/Re-Select Failed |
SCSI Adapter fails to
respond
to re-selection within 250ms after device gains
bus arbitration.
Re-selection attempted second time before
setting select/re-select
failed status. |
47
|
SCSI Interface
Parity Error |
Device detects incorrect
parity
on SCSI data bus (CABLE). Check cable
connections, cable termination, cable length
(max 6m or approx. 20 feet). |
48
|
Initiator
Detected Error |
SCSI Adapter/A detects
error,
sends retry message, detects error again, sends
retry message 2nd time. Probable hardware
problem. |
49
|
Inappropriate/
Illegal Message |
SCSI Adapter/A sends
message
that is not supported or is not in a logical
sequence. Probable software error. |
4C
|
Logical Unit

Probably a hardware
failure in device being
tested. |
4E
