I don't think so. I have used Apple and Toshiba drives with no problems. I have used AmiCDFS and the OS3.1 and OS3.9 CD FileSystems.
If you are having problems chip the cables and termination (Terminate only at the ends). Some A3000s have a bug that keeps them from providing terminator power, so you may want to jumper a device or two to supply it if possible.
You may need to upgrade your SCSI chip if it is a real old one. Unfortunatly I forget how to tell which chip you have.
