Many current machines ignore the high density notch in 3.5" disks, and do some sort of software density detect. Similar logic is used (I assume) for 5.25" drives. I have a problem sensing the correct density on non-DOS disks. The drive continues to treat the disk as the same density as the last DOS format disk read. This is true on both a clone, and a COMPAQ (386). Anyone have any helpful hints? I've tried reading a sector with int 25 and int 13, but neither seem to do anything to adjust the density. It reads the data correctly, but still thinks the number of sectors per track are the same as the last DOS disk. I'm guessing that there is some device driver structure out there that I need to adjust. -- * George R.
