- Wait a sec! I missed the original post describing the Tandberg problems
- some people are having. Could someone send me a copy or synopis of them?
-
- I just acquired a Tandberg 3600 drive (150/250 mb) that was supposedely
- a refurb pulled from an RS6000 and it has worked flawlessly for me so I
- am interested in hearing what problems other people are having. I do not
- know the EEPROM or BIOS revisions on the drive. The system I am using it
- in is an A3000T with AmiBack 2.0 software. I have used it to back-up and
- restore MANY megs of data (and am using it as I type this as a matter of
- fact) with never a problem. I do not need to turn reselect off and I do not
- experience any noticeable slowdown - AmiBack keeps the tape streaming
- constantly and I get data transfer rates of about 5 megs/min. The only
- thing I had to do was set IO mode to Synchronous instead of Asynchronous
- on the AmiBack tape configuration window or else AmiBack reported some
- spurious errors.
