SENSE DATA BYTES WORDS 10 thru 17 contain data returned by the drive after receiving a Request sense
command from the ODC. A Request Sense command is issued if the drive returns a
status of 02 Hex "Check Condition". Data sense is valid if the first byte is 70 or F0 Hex.

detected while executing the SCSI command. All bits = 0 indicates no errors
detected. Bit 15 = Target not found. Bit 14 = Loss of busy. Bit 13 = Illegal
