- Just to add to the confusion:
-
- I did order the new BIOS for the drive, and guess what: it worked worse than
- before. I replaced with it with the original U07 BIOS and it worked as "well"
- as it had before. Tandberg would not take the BIOS back, BTW, even though I
- bought it on their advice (just a minor update, the price is $40, no $60 as the
- y
- originally told me.
-
- Using the original BIOS, I do have it running, although it backs up very slowly
- 2.2M/minute).
-
- The key here is the Tandberg seems to drive other SCSI controllers bananas
- the way it does asynchronous writes. I suspect is has to do with how slow the
- drive writes to the tape (a block takes several seconds to write).
-
- I have it working by turning reselect off. Using the GVP, there is a command
- that does this. The net effect is the backups go about twice as slow as they
- would otherwise, but they work.
-
- Look at it this way; the drive was relatively inexpensive (just over $200), so
- be happy you can back up your HD without swapping floppies. Sorry I don't
- have better news.
