Ultrium 215: newly bought tapes give write error old ones not

I recently bought new tapes for my Ultrium 215.
All the new tapes I used so far give me write errors.
The old tapes which I have work without a problem. I've updated the firmware to the latest version. What could this problem be?

Hi,

Have you bought the same compatible tapes ?

Some Ultrium Tape Model Numbers.

http://www.hp.com/products1/storage/products/storagemedia/tape_ultrium/index.html

Firmware updates should not give problems to the same ( model ) of the tapes..

It maybe that new tape or tape lot is faulty or the lock (read / write) of the tape have internal problems.

You can only try this tapes on other drive if possible.

Thats all i could say.

Regards,

Hi,

Some more details on the tapes you are using would be helpful, brand, capacity etc.

Also, if you download LTT and generate a support ticket, zip it up and attach it here, I will be able to see a log of the last tapes you have been using and hopefully ascertain the exact error by tape.

Cheers,

The "old" tapes are HP C7971A the new ones are also HP C7971A.

I've also used Maxell Ultrium 1 data tapes. They give the same result. Old ones give no problem the new ones give an error.

I've included a support ticket of the tape drive.

Hi Yvo,

Ok, thanks for the information.

Your drive is suffering from severe write and read performance. Write and read error rates are very poor and this is leading to a large amount of write and read retries and sometimes hard errors. This is occuring on both old and new tapes, its just that you have only seen a hard error in the new tape.
Your drive has its cleaning flag set and so a cleaning tape might help recover the situation. However, there is also the chance it will not. If you still have problems after cleaning I would phone up HP support and see if you can get a warranty replacement.

Cheers,

Dave Dewar
