Field Value Description
PS 0 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 SELECT command.
EER 0 Enable Early Recovery. Not supported by the drive.
PER 0 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 after retries.
DTE 0 Disable Transfer on Error. Not supported by the drive.
DCR 0 Disable Correction. When the value is 1, it disables ECC
correction (but not retries) 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.
Verify Retry Count 4 The Verify Retry Count specifies the number of retries that are
attempted per sector on a failed READ portion of a VERIFY
operation.
Verify Correction Span 170 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
Verify Recovery 0 The Verify Recovery Time Limit specifies (in milliseconds) the
Time Limit 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 minimum
permissible is 100 milliseconds.
NOTE: Fully supported and temporary fields are underlined. Unsupported fields are not underlined.
The PS bit is underlined, meaning it will be set on a MODE SENSE command, since the page
is savable.
