I now want some of these disks to be MSDOS compatible. I used the program Diamond Format which is capable of writing a MSDOS boot sector without reformatting my disks, however MSDOS only recognizes the first 360K on the disk. I presume it writes some type of info on the boot sector to indicate the number of tracks and sectors it was formatted in. Could someone tell me where it is so I could use a disk editor to manuall change it? Steven Lee
