Verify Error Recovery Page; Verify Error Recovery Page-Field Descriptions - Maxtor ATLAS 10K III Product Manual

SCSI Description
The Verify Error Recovery Page controls the drive's response to error conditions that
arise during the VERIFY command and during the verify operation of the WRITE
AND VERIFY command. The Verify Error Recovery Page is not supported in the
SCSI-1/CCS Operating Mode. The data format and field descriptions are described
in Table 5-68 and Table 5-69 respectively.

Fully supported and temporary fields are underlined. Informational fields are
not underlined. The PS bit is underlined, meaning it will be set on a MODE
SENSE command, since the page is savable
Parameters Savable. This bit is only used with the MODE SENSE command. A
returned value of 1 indicates that the target is capable of saving the page in a
non-volatile, vendor-specific location. The bit is reserved with the MODE SE-
LECT command.

Post Error Recovery. When the value is 1, the drive returns CHECK CONDITION
status for recovered errors, sets the sense key to RECOVERED ERROR, and
posts the appropriate additional sense code.
When set to the default value of 0, it causes the drive to return GOOD status in
cases where error recovery is invoked and is successful. The only recoverable
error that can occur during a VERIFY operation is a failed read that succeeds af-
ter retries.
Disable Transfer on Error.
Disable Correction. When the value is 1, it disables ECC correction (but not re-
tries) on the READ portion of a VERIFY operation. When set to the default value
of 0, the ECC correction is always applied as a means of recovering erred data.
The Verify Retry Count specifies the number of retries that are attempted per
sector on a failed READ portion of a VERIFY operation.
The Verify Correction Span specifies the maximum number of bits in a sector
that the drive is allowed to correct. A value less than the default value can cause
an otherwise correctable error to be reported as uncorrectable. If the initiator
specifies a value larger than 80, the drive rounds down to 80 without reporting
the change. A value of 0 causes the drive to use its default value
The Verify Recovery Time Limit specifies (in milliseconds) the maximum time
that a retry is attempted on a failed sector during the read portion of a verify
operation. The default value of 0 indicates that there is no time limit. The mini-
mum permissible is 100 milliseconds.
