HP DLT drive, cannot perform catalog, no error messages

Hi, I can't seem to complete a catalog of any of the tape backups I created a while ago. The tape drive just keeps cycling through the tape endlessly. It's not generating any errors. I used this drive for 3 months without any issues. I'm Veritas Backup Exec 8.6. I've tried reinstalling the drive, I've even tried moving it to a new server and setting it up there, still no luck. We had some random power fluctuations a couple of weeks ago and I thought the drive might've gotten screwed up so I had it replaced, but I'm still having the same problems. I'm assuming at this point it might be the SCSI card it's attached to, or the terminator on the drive might be bad. If anyone could point me in the right direction before I start replacing other parts I'd appreciate it. Thanks

Hi CATech,
How old are the tapes? I can think of two things that would cause these symptoms:
1. The tapes themselves are no longer functional. (In this case the data is gone)
2. The tape drive used to create these tapes, had offset heads. (In this case the data will be difficult to recover and should be sent to a professional data recovery service.)

To test whether or not the tape drive itself is functional, you should get a new tape and record something to it, then catalog and read it. If you are able to do so without difficulty, then I would suspect that your tapes are at fault.
If you are unable to do so, then something is wrong with the tape drive itself. (Or one of the components in between. I would suspect that the termination is fine as the SCSI chain wouldn't work if it wasn't.)

Hope this helps!

As it turns out the tapes were the problem. I didn't think they would be as they're only a few months old. Only the tapes that were used after the power failure had a problem, so my guess is that the install of backup exec or it's MSDE database got corrupted and messed up the tapes. I was able to erase and reuse them. Thanks for your help.
