- Wunnerful. I got the same errors and sent my tape drive out for repair, I
- get back from vacation and see this thread.
-
- Anyway, we have 2 exabytes. I was going to move our dump from one to the
- other for convienance and found I could no longer write to it. I tried
- using tar and it wouldn't write to the tape either. Cleaned the tape
- head, tried a new tape, re-seated the SCSI cable, moved the drive to a
- different Sun, no luck. Called the vendor and he said to send it back,
- it's only 6 months old and still under warranty. The other Exabyte works
- like a champ.
-
- The Exabyte has an internal RAM buffer, when the buffer is full the block
- is written to tape. I suspect this is why you get the error 753 feet into
- the tape, thats the end of the first block (this is a guess, I didn't
- check it out). I did verify the error occurred before any blocks got
- written to tape.
