IIRC, you could no longer use 400k disks as of System 7.6, but you can still use 800k disks up through System 9, provided of course that you have a Mac with an internal floppy drive. The external USB drives are, for the most part, PC clone laptop style drives, and therefore can not read or write the GCR disks. But, you _can_ write 400k floppies on System 7.6 and up with Disk Copy. You can't mount the image, and you can't mount the disk you created, but it does work. Once again, you have to have a Mac with an internal floppy drive. Why Apple stopped offering floppy drives, I don't know. I know that the first peripheral I bought for my G4 was a floppy drive, and I still hate the fact that it's slow as hell, and doesn't have auto eject.
