Good luck finding any, at least in the US. Possibly more luck in japan. I had a 120/230MB SCSI M-O drive, it was great. The disks are the size of a fat 3.5" floppy, store as much as a Zip, and are nearly indestructable. If you really want to archive some data, put it on an M-O disk in a caddy. I was given the drive for free, and I had a bit of trouble finding blank media. I found some under a several-millimeter-thick layer of dust at a retail store once, the SKU was no longer in their inventory system even. I got them for cheap, but that was .. years ago. 640MB M-O are probably still in use, somewhere, so you might have better luck with that size. Perhaps you could get in touch with a Fuji distributor?
