On the whole the new media cycle is OK, but 3 of the DLTs are showing errors stating that they have reduced capacity. On checking the media statistics I have noted that these tapes have anything upward of 15,000 soft-write errors incurred though they have only been used once. Before I speak to HP about replacing the tapes, I was wondering if anyone had any suggestions of possible ways to return the tapes to maximum capacity? The only thing I have tried is erasing (quick & long ) the tapes.
Thanks

Re: Reduced Capacity DLT IVs
Have you been using the same cartridges as before?
Has this problem been here as soon as you replaced the DLT drive?
This problem can happen if the new DLT tape drive has a newer firmware level than the old one (which is quite plausible). Newer firmware detects more tape errors than older firmware, and more efficiently. It could be that the cartidges were already faulty before the tape drive change, and were only recognised as such by the new firmware. We had such cases when after a firmware upgrade to tape drives, the tape drives themselves went faulty after a few backups for the same reason.
Contact HP for clarification.
HTH,
Vince

Re: Reduced Capacity DLT IVs
Ok, now I see that the tapes have only been used once... :-)
Then, the problem may be firmware (again!). It is recommended that you have firmware v59 on DLT drives. Firmware levels before that can cause write errors on the cartridges, something like you are experiencing.
Check the firmware level and update to v59 if you have lower than that.
HTH,
Vince
