If you are not sure, don't create device entries for those formats, so as toĭrive-independent device files which automatically detect the media format and capacity:ġ12 Description fd special files access the floppy disk drives in raw mode. Usual 40/80 are supported should not damage it, but no warranty is given for that. Warning: If you use formats with more tracks than supported by your drive, you may cause it mechanical damage. To this base number, add the drive's number on its controller and 128 if the drive is on the secondary controller.
