I have an external SCSI 1Gig hard drive I bought a few years ago that I would like to format using Apple's Drive Setup v 1.8.1 (ships with OS9). Regardless of what I do, I get the "cannot modify disk in an unsupported drive" message. I've formatted it with a few 3rd party programs, hoping Drive Setup would then let me format it with Apple's drivers. The reason for this is, I am considering installing Linux on the drive, and Drive Setup 1.8.1 allows the creation of Linux partitions. Even if I don't put Linux on it, I would still like to use Drive Setup on the drive. The drive is a Fujitsu M1606S-512 (according to TechTool Pro 2.5.2) external packaged as an Arriva drive.
