A400: Read Error
178 SuperLoader User’s Guide
Cause 5 This error could be due to one or more of the following:
• A bad spot on the media
• A failure of the drive to determine the data read from the tape was
good due to CRC
• Other indicators used by the drive to insure data integrity
• The data originally written was not written correctly.
Suggested
Actions 5
Following is a list of suggested actions:
• Verify if multiple events on the same media occur, or multiple events
on different media occur. With this information, you can determine if
the failure is caused by the media or the drive.
• Make sure the event is not due to media being written badly by some
other drive. To confirm the media was not written incorrectly, look
for A401 events with the same media ID on this drive and other
drives this media may have been written to.
• Run a Tape Drive Write/Read test with two pieces of media. If test
fails, replace the DCA.
Note: If the drive logs this error, the cleaning light may be turned on
recommending a cleaning as well.
