||What it means:
||NO SENSE. Indicates that there is no specific sense key information
to be reported for this device.
||RECOVERED ERROR. Indicates that the last command completed successfully
with some recovery action performed by the target. Not a fatal error.
||NOT READY. Indicates that the device addressed cannot be accessed.
Operator intervention may be required to correct this situation.
Probable causes of this error:
Winchester: Wait spin jumper installed or performing self tests.
Optical: Cartridge not inserted or START button not pressed.
Tape: Tape not inserted and loaded.
||MEDIUM ERROR. Indicates that the command terminated with a nonrecoverable
error condition that was probably caused by a flaw in the medium or an
error in the recorded data. A winchester disk showing this error
should be formatted. A tape can be retried, but the data integrity
is probably suspect. This is a fatal error on the optical disk.
||HARDWARE ERROR. Indicates that the device detected a nonrecoverable
hardware failure while performing a command or self test. This could
be a device or controller failure.
||ILLEGAL REQUEST. Indicates that there was an illegal parameter
in the command descriptor block or in the additional parameters supplied

firmware or interferance on the SCSI bus.
||UNIT ATTENTION. Indicates that the removable medium may have
been changed or the target has been reset.
||DATA PROTECT. Indicates that a command that reads or writes the
medium was attempted on a block that is protected from this operation.
Disable the write protection on the tape or cartridge and continue.
||BLANK CHECK. Indicates than an unwritten block wan encountered
while reading a tape or optical disk cartridge, or a written block was
encountered while writing an optical disk cartridge.
