Lines: 16 I also had the problem of how to backup the Minix disks. I had the PH 1.5 distribution on 3.5" floppies. Left to its own devices diskcopy on my Zenith assumed that the disks were only 40 tracks apiece. (This was the side effect of the non-MSDOS format it found when looking at the disks). I ended up writing a fairly crude program that used the INT13 interface to read the originals and write out a copy. - A side effect I had was that I had to do a 'dir' on a standard DOS 720k disk before running my program. I assume that this was to do with the auto density/type detection code in the standard BIOS drivers. I imagine the differing replies here depend on whether people were copying 360k disks in 360k drives, 360k disks in 1.2M drives, 720k disks in 720k drives, or 720k disks in 1.4M drives!
