Where can i find information on all floppy disks?

int 13h says i can only get 1 - 63 value for sectors, but fat12 says its 18 sectors per track (unless ive mis read) is that 1 - 18 per track or 0 - 17 (18 sectors) i know it says 1 - 63 but id just like to make sure.

63 is the maximum number of sectors to read with one BIOS call. If you want to read a full track a time, use 18. What's the problem?

Start at 1, 1-18

There need not be a floppy disk at the receiving end when you call int 13h. An eltorito cd or usb key works too.

That said, reading across floppy tracks is asking for portability issues.
