assuming it is not a U2W drive which does not have on-board termination.
U160 and U320 drives don't either for the record. And before you ask I have a pair of U160 Cheetahs in my 840av (I know I'm mad).
These complications of termination are why I strongly recommend against folks using adapted drives, including the widely available SCA drives. If you know what you're doing it can be made ot work, but if you don't know, and aren't inclined to carefully study SCSI termination issues, then adapting a 68 pin or 80 pin drive to a narrower bus is a *bad idea*.
It's not a bad idea at all, it just requires a lot of 'try it and see'. Isn't it recognised that man learns best from his/her own mistakes?
To make things worse, SCSI voodoo, as its called, happens because sometimes (often) SCSI will appear to work even when you configure things incorrectly. This can lead to unnoticed corruption of your devices
Corruption? I never knew that was possible in a Democracy *AHEM* I mean on a SCSI bus.
or just a bus that works okay and lends you a false sense of security. Then one day it stops working, and you declare "SCSI voodoo" when what really happened is that it was wrong all along and suddenly the SCSI bus noticed.
That's happened before. It's usually when I plug in a CD drive to re-install the OS.I have a 512MB hard disk the that won't work woth any other devices on the bus on an LC475 (tried in 3 machines) but *will* in an LCIII, odd or what??
