SONY SDT-10000/SDT-11000 DDS Tape Drive
Description
HARDWARE ERROR. Indicates that the drive detected a non- recoverable hardware
failure not related to the tape (for example, controller failure, device failure, parity
error, etc.) while performing the command or during a self test. If a previously ac-
knowledged WRITE-type operation was the cause, the Valid bit is set. The Error
Code in Sense Byte 16 will indicate the specific problem. Refer to the Error Code
table in the Diagnostics section for more information.
PERIPHERAL DEVICE WRITE FAULT - Drive electronics did not report successful
completion to a Write operation.
TRACK FOLLOWING ERROR - Mechanical motion timeout,
Servo loopback failure, Drum or Capstan speed out of expected tolerance
MECHANICAL POSITIONING ERROR - Cassette Compartment motion is im-
proper.
INTERNAL TARGET FAILURE - Any unexpected internal error
conditions indicating a non-recoverable hardware failure. Refer to the Field Replace-
able Unit Code field (Sense Byte 14) to determine which part of the drive is failing.
Host should issue SEND DIAGNOSTICS with the Self-Test bit set to thoroughly test
the drive. This Sense information could also be returned after a SEND DIAGNOS-
TICS command ends with a CHECK CONDITION Status. Host should issue RE-
CEIVE DIAGNOSTICS RESULTS for more details. Possible causes:
Buffer overrun/underrun, Format violation, Mechanical status timeout, internal data
parity error, byte count mismatch, incorrect micro processor operation, unexpected
SCSI protocol chip interrupt
MEDIA LOAD OR EJECT FAILED - Unable to complete Load or Unload operation
successfully. Possible causes: Mechanical problems or Read/Write failure in test sec-
tion of the media
