I also figured out you can cross the tracks and formats for 1.44M (now very unstandard, unless we all get together on it). Rumor has it that the 3.5 1.44M drives are 160 tracks per side and rotate at a completely different speed, however I lack proof. I would very much like to bypass 5.25" HD and use 1.2 to 1.44M 3.5". I would also recommend 512 byte sectors to stick to the 'standard' as disk utilities barf otherwise. The BIOS I/O, FORMAT-TRACK, and DISKCOPY.COM and FORMAT.COM would all have to be patched. A permanent patch would suit me fine, as I would really see no need to use the 1.2Z format. Cheers, Gern -------
