Basically this. For FAT to work as a standard it specifies track, sector etc. While all PC people used to think of HD 3.5 in floppies and 1.44mb, they were different capacities on other devices. My Amiga writes 1.760mb on a HD floppy because the layout on the disk is different. Most (all?) USB floppies take care of the track/sector stuff and let the OS worry about the next level up. To read/write a Ensoniq floppy you need it to give the lower level stuff to the computer.madtheory wrote: Does the HxC software do some very low level access on the drive that it can't do over USB?
(Basically the reason is a USB floppy acts as a class compliant mass storage medium like a USB flash drive. For that to happen it can only give the OS control over certain parts of the process, the same parts it gives with the flash rom. Tracks and sectors aren't part of that.)
