Given that the disks are circa 1997 you'll want OS 8.1 or 9.x.x on that Mac. Forget eBay for getting a drive. Since Fujitsu quit the MO market, sellers have been starting MO drives on there at stupid high prices, but disks can still be picked up cheap. A 640 meg drive would be a good one to get, especially with LIMDOW (Light Intensity Modulation Direct OverWrite), so you can use it to read and write any 3.5 MO disk 640 meg or smaller. (LIMDOW makes writes 2x faster, but only on LIMDOW capable disks.) I just searched eBay, looks like all the drives on there are the higher capacity 1+ gig types. I dunno about the compatibility of those with lower capacity disks, looks like most of the ones on there are 5.25 The disks can also be read with a PC running a Mac emulator like Basilisk II or Sheep Shaver, also with a SCSI card like an Adaptec 2940. Those cards are cheaper than dirt on eBay, even the ones with Mac compatible BIOS. Most of the smaller capacity MO drives use narrow, Single Ended SCSI so you'd want a SCSI card with the 50 pin connector. Don't get a differential or LVD (Low Voltage Differential) SCSI card for this. Those are mainly for use with SCSI drives that have the SCA80 connector. I have a couple of MO drives, a 320 meg and a 640 meg, but I'm not ready to part with them. Still got a bunch of old Mac stuff to get off some disks, same story with a stack of Zip 100 disks I keep not getting around to doing same with. If my 128 meg MO drive hadn't up and died I'd give it to you for the shipping cost.

I have plenty of old Macs either with native SCSI or a SCSI card installed. I just need to purchase a MO drive (provided the data on the disks is of value that warrants that hassle and expense). --glen -- - You received this message because you are a member of the Vintage Macs group.

Re: What is a Mac formated Komag 128 Rewritable disk?
Glen, It sounds like that would be a 128 MB HFS formate Magneto Optical disc, they where a common high capacity rewritable media in the 90's. You can just search something like Fujitsu Magneto Optical on ebay and come up with a drive, I do believe there where even external USB ones made.

RE: What is a Mac formated Komag 128 Rewritable disk?
Sounds like it is a 128Mb MO indeed. Does the disk look like this? http://skinflint.co.uk/a270272.html I've got a few of them and a drive here that I had hooked up to my PC for a while. Looks like they aren't all that easy to come by on ebay...at least not outside of the folks that $100-200+ for them. I don't even recall where I got mine now...
