I know.. that's why I said 'if' and the #2 options. I'm working on a
DOS program to format the disk and write the tracks, and probably will
write a quick 50-liner to read the disks (this is in assembly), which
I'll post once I get it to work. Does anyone have info or links to
relevant info on the necessary ioctl's for Linux's floppy device driver?
