ioscan says that they are HP35480A inside.
I am trying to use one of these and when I insert some to the tapes it just reject them.
Some of them work just fine and others when I put them in the drive they seam like the are going to work but after a few seconds they eject.
I have tryed new and used tapes. I have tryed 60M, 90M and 120M. Digitial, HP, Maxell, and Fukifilm. New and old alike. Oh DDS, and DDS1,2,3.
And I have replaced the Drive once.
When the tape stays in the drive it works fine.
Am I missing some thing here?

Re: DAT tape drive strangeness
You could also be seeing old hung processes so that as soon as a tape is available, it tries to rewind and eject the media. To eliminate that possibility, I would disconnect the tape drive from the host and see if the media then behaves itself. If the problem arise only when connected to the host then I would tend to suspect faulty termination. Bad/missing termination can cause a drive to almost work perfectly -- the worst kind of problem. Look for termination enabled on the drive itself and an external terminator -- this would be bad.

Re: DAT tape drive strangeness
I didn't know that there was differences in DAT/DDS tapes.
When we replaced the 2 servers a couple years ago we had no need to have a DAT drive.
Well, someof our Apps updates come on DAT tables and I can't get all of them to to use CD, DVD, or DLT so I broke down and bought a couple cheep DAT drives.
I always read/write and DAT/DDS the tapes at home with the old junk I use at home. Never gave it a thought about tape being different.
Well I know now. And you get what you pay for.
Thanks you for taining me again.
Marty

Re: DAT tape drive strangeness
If you've ever inserted a 120 minute cassette tape into a car stereo, you probably discovered that longer tapes are not always compatible (as you try to unwrap the tape from the mechanism). New tape drives can cost 2 to 10 thousand dollars and if the drives did not protect themselves, there would be a lot of drive repairs and unhappy customers.
