Data error (cyclic redundancy check).

[Neil Charman]

We currently have 2 HP storageworks SSL 1016 tape autoloaders daisy chained together running of backup exec 9.1 on a windows 2003 server. Backup jobs on the new autoloader are now failing with the error:

Storage device "HP 4" reported an error on a request to write data to media.

Error reported:
Data error (cyclic redundancy check).

Veritas are insisting tha this is a hardware related error possibly to do with scsi connections/speeds

Even if we just plug the new autoloader into the server directily and take out the first autoloader, then jobs still fail with the same error.

From my experience, the "CRC" message is more likely the result a write verify error on tape, and not a connectivity/cable error.

What drive type do you have? Have you tried to isolate it to a particular tape?

If you can install HP L&TT (www.hp.com/support/tapetools), I would recommend running the "drive assessment test", which will check the drive's functionality and error rates. You should run it on a new tape.

You can also generate a support ticket and paste it here, and I can review the drive's error logs to see what it's returned previously.

I have tried numerous tapes, i have actually spoke to HP and they are swapping the device out, so will try again with the new kit.
