I have a 100% adaptec compatable SCSI-2 card and I was wondering if hard drives like Ultra Wide SCSI, SCSI-3, Wide SCSI and others would work on my SCSI-2 card

Yes it would work. However, you will need special cable adapters to interchange the connections for SCSI-1,2, and 3. Fast SCSI, Wide SCSI, Ultra-Wide SCSI, and Fast Ultra-Wide SCSI are all different variations on SCSI-3.
Also, you will lose the capabilities that SCSI-3 provides, if you connect to a SCSI-2 card. For example, if you connect a SCSI-3 hard drive to your SCSI-2 card, it will work, but only at the SCSI-2 speed of 10MB on an 8-bit bus, instead of the 20MB.

if you're going to use ultrawide SCSI drives, get an adapter that supports it. you would be loosing way too much performance otherwise! Anyway, one of those adapters only costs a little bit more than a SCSI-2 version, and you can connect up to 15 devices!
