Non-Apple drives work quite well with Macs; however, while your
observation about the use of Apple's HD SC Utility is correct,
all non-Apple SCSI drives sold *FOR* the Mac come with their
own SCSI setup utility.

For a SCSI drive *NOT* sold _for_ a Mac, you'd need a third-party
toolkit like FWB' Hard Disk Tools (or whatever it's called). I've
used it to add IBM and DEC SCSI drives to a Mac.
