Finally figured out the problem with the USB to SCSI adapter not working with my Jaz 2GB drives. Turns out the SCSI id must be set to 0 for the adapter to work. I tried it with termination off and on, and this made no difference. The SCSI id was the difference on my Jaz 1GB drive – I’m glad I remembered that little fact.
So the adapter works now, but, as expected, is not fast. As a test I tried to copy a 275 MB file to a Jaz 2GB drive on the USB to SCSI adapter. Windows said it would take about 10 minutes to complete. I did not time the whole file to see the actual time, since I figured if Windows was anywhere close to accurate it would be a lousy interface to use. I figure I’ll use it if I have problems hooking up the Jaz 2GB to the Dell PC at the office with the Adaptec 2930 card; otherwise it is still a nice accessory to have in a pinch.
