Progress Indication indicates the rate of formatting completion when the
denominator is 65536 (10000h).
INIT should not use the REQUEST SENSE command alone to
check the ODD status. Because the REQUEST SENSE command is
used by INIT to retrieve sense data that is held by the ODD on
various occasions, the contents of the sense data depend on the
results of the command executed previously.
Example:
Response when the ODD is in Not Ready state
When INIT issues the TEST UNIT READY command,
the ODD ends processing with Check Condition Status
and responds to the REQUEST SENSE command with
Not Ready Sense Data. When the INIT issues the
INQUIRY command, the ODD responds with Inquiry
Data and ends processing with Good status. If INIT
continuously issues the REQUEST SENSE command,
the ODD responds with No Sense because the previous
command has ended normally and the ODD holds no
sense data.
