2.4.1.1.4.3 Actual retry count sense key specific data
If the sense key is HARDWARE ERROR, MEDIUM ERROR, or RECOVERED ERROR, then the SENSE KEY SPECIFIC field shall be as shown in table 20.
SKSV bit
The SKSV bit is described in 2.4.1.1.4.1 for descriptor format sense data and in 2.4.1.2 for fixed format sense data.
ACTUAL RETRY COUNT field
The ACTUAL RETRY COUNT field returns vendor specific information on the number of retries of the recovery algorithm used in attempting to
recover an error or exception condition.
NOTE This field should be computed in the same way as the retry count fields within the Read-Write Error
Recovery mode page.
2.4.1.1.4.4 Progress indication sense key specific data
If the sense key is NO SENSE or NOT READY, the SENSE KEY SPECIFIC field shall be as shown in table 21.
SKSV bit
The SKSV bit is described in 2.4.1.1.4.1 for descriptor format sense data and in 2.4.1.2 for fixed format sense data.
PROGRESS INDICATION field
The PROGRESS INDICATION field is a percent complete indication in which the returned value is a numerator that has 65 536 (10000h) as its
denominator. The progress indication shall be based upon the total operation.
NOTE The progress indication should be time related, however this is not an absolute requirement. (E.g.,
since format time varies with the number of defects encountered, etc., it is reasonable for the device
server to assign values to various steps within the process. The granularity of these steps should be
small enough to provide reasonable assurances to the application client that progress is being made.)
