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.
