SCSI Description
Maxtor Atlas 10K III 5-137
Supported Sense Keys
NO SENSE 0h
There is no specific sense key information to be reported for the designated
logical unit. This is the case for a successful command or a command that
received CHECK CONDITION or COMMAND TERMINATED status because
one of the following bits is set to 1: File Mark, EOM, or ILI.
RECOV-
ERED ERROR
1h
The last command completed successfully with some recovery action per-
formed by the drive. Details may be contained in the additional sense bytes
and the Information field. When multiple recovered errors occur during one
command, the choice of which error to report (first, last, most severe, etc.)
is device specific.
NOT READY 2h
The logical unit cannot be accessed. Operator intervention may be required
to correct this condition.
MEDIUM
ERROR
3h
The command terminated with a non-recovered error condition that was
probably caused by a flaw in the medium or an error in the recorded data.
This sense key can also be returned if the drive is unable to distinguish be-
tween a flaw in the medium and a specific hardware failure (Sense Key
HARDWARE
ERROR
4h
The drive detected a non-recoverable hardware failure while performing the
command or during a self-test. The error type could be controller failure, de-
vice failure, etc.
ILLEGAL
REQUEST
5h
The drive detected an illegal parameter in the Command Descriptor Block or
in the additional parameters supplied as data for some commands. If the
drive detects an invalid parameter in the Command Descriptor Block, it ter-
minates the program without altering the medium. If the drive detects an
invalid parameter in the additional parameters supplied as data, the drive
may have already altered the medium. This sense key may also indicate that
an invalid IDENTITY message was received.
UNIT
ATTENTION
6h
The drive generates this sense key whenever the drive is reset by a TARGET
RESET message, a hard reset condition, or by a power-on reset. Other con-
ditions that generate a UNIT ATTENTION include:
The mode parameters in effect for this initiator have been changed by an-
other initiator.
• The microcode has been changed.
• Tagged commands queued for this initiator were cleared by another initi-
ator.
• INQUIRY data has been changed.
• The mode parameters in effect for the initiator have been restored from
non-volatile memory.
• Other events that require the attention of the initiator.
DATA
PROTECT
7h
A Read or Write command was attempted on a sector that is protected for
this operation. The requested operation was not performed.
VENDOR
SPECIFIC
9h This sense key is used to report specific Maxtor conditions.
ABORTED
COMMAND
Bh
The drive aborted the command. The initiator may be able to reissue the
command successfully.
MISCOM-
PARE
Eh
The source data did not match the data read from the medium (i.e., a mis-
match).
