Does anyone know if you can use an older external SCSI HDD (like 20sc), and put a much larger drive in it (in older 68k macs), and have older Mac OS use it OK?

Hardware-wise works fine.

Does anyone also know of 68k mac drive limitations?

The built-in SCSI in the 68k machines was an older rev of SCSI-1 Narrow. So you need to stick to drives that talk to that spec reasonably. IOW, I'd stick to SCSI-1 or SCSI-2 or SCSI-2 Fast drives. Don't go wide or SCSI-3, even with adapters; you could end up with timing problems.


Then there are OS limitations; you didn't mention what system you're running. System 7.5 increased max volume size to 4 GB. As I recall, I think that ment you could use bigger drives, but they had to be partitioned. System 7.5.2 raised that max to 2 TB.
