Hi,
Interestingly enough, I just searched the web for HP Surestore before I contacted HP about my dat tape drive. I have a dat24i drive that worked fine on a WindowsNT box that I had a couple years ago. Then I had the box rebuilt and the drive never read tapes again. HP sent a new drive, but the company rebuilding the box never could get it to work either. Last year I had an XP Pro box built and put the dat drive in it.
I have been quite lucky for the past couple years running with no backup (I'm embarassed to admit that). Well that streak ended last week when I lost some important files. So I started looking at my dat problem again. The guy I was working with noticed that the tapes(DDS1) were rewound past the header block. When I put the tape in I would get a yellow 'clean' light error. The tape would not eject until I rebooted.
I contacted HP and they wanted me to update the firmware. After reading your message, I was somewhat afraid of the results. We updated the firmware('flashed' is the term HP prefers). The first time we did a hardware scan and it found the drive. Then we ran some tests.... The next time we opened the Library and Tape Tools, the default was "Save, Manual Scan". I was told to use that. This time the Drive was not found and we had to do a Hardware Scan again to find the drive.
Was this anything like the problem you were having?
I figured out that if I manually wound the tape onto the front spool a little, everything was fine. I was actually using a 3rd party 'tar' format to read and write(HamiltonLabs.com).
If you would like to talk about this get back to me and I can give you a toll-free number to reach me on. If you are interested in calling HP and referencing my call case #, let me know and I can get that to you.
