1) XFD: subtract -16 Bytes (ATR Header), therefore add +384 Bytes! (XFD saves the full boot sector size / disksize, BUT it does not / cannot save the full sector data – these additional 384 bytes are simply empty!)

2) full byte size / disksize (has 128 bytes boot sectors, thus no need to subtract 384 Bytes!)
3) byte size minus boot sectors (has 256 byte boot sectors, thus 3x 128 bytes = 384 bytes already subtracted, since the Atari OS only allows 128 byte boot sectors from diskette! the real disksize is therefore 384 bytes larger, but that data is not transfered from the floppy to the computer! most A8 floppy drives would require a firmware change to read/transfer full 256 bytes bootsectors)
4) harddisks can use full 512 bytes for bootsectors! floppy disks are still limited to 128 bytes bootsectors!
