On: Emulating the Early Macintosh Floppy Drive

[ForOldHack]

There were USB drives that sold for iMacs,but the ability to read MFS (400 and800k) floppies disappeared soon afterwards..

As far as I recall, none of the USB drives of the iMac era could read 400/800K GCR disks, they were PC drives that could only use 720/1440K disks. The Imation SuperDisk drives could also use their own 120MB “floptical” disis. Later versions extended it to 240MB, and could also write 32MB to a standard floppy disk. MFS refers to the file system used on 400K disks. 800K disks used HFS.
