VERIFY verifies one or more blocks beginning with the next block on the tape. Both
CRC and EDCs are validated.
Immed
If this bit is set, the Verify command will complete before any media movement is done
(that is, when processing has been initiated).
BC
This bit selects a CRC/ECC verification or a byte-by-byte compare. If the BC bit is
cleared, the device is instructed to perform an internal CRC/ECC check of the data.
If this bit is set, the command will be rejected.
Fixed
This bit operates in the same fashion as with the READ command.
