HDs initialised with Non-Apple drivers are a pain to reformat. If you have a newer computer, I would suggest plugging it into that and reformating with the latest Apple Drive Setup (This is how I got my drive working). If you don't have a newer machine and/or it lacks SCSI, try sticking ADS onto a floppy and reformatting the HD while booted off the CD. If it still won't work properly, use ADS with Zero all data and Low-level format turned on. If that fails, well, small SCSI HDs are fairly cheap right now or you could try to dig up a copy of FWB Toolkit somewhere to reformat it. Good luck!
