REQUEST SENSE returns the CHECK CONDITION status only to report fatal errors for the REQUEST SENSE
command.
For example:
The target receives a non ZERO reserved bit in the command descriptor block.
An un-recovered parity error occurs on the Data Bus.
A target malfunction prevents return of the sense data.
The Allocation Length falls between block boundaries.
Following a fatal error on REQUEST SENSE, the sense data should be considered invalid. The host may attempt
recovery by selecting the drive and issuing a BUS DEVICE RESET message directly following the IDENTIFY
message. This forces the drive to do a hard reset. If the fault persists, the host should deny access to the drive.
