Is the capacity of the diskette 800K? or is that merely the name of the
type of the diskette, with an actual capacity of somewhere between 640K
and 800K?
If the actual capacity is 800K, with MFM, then it would probably be 80
track, double sided, with either 10 512 byte sectors or 5 1024 byte
sectors per track. (can't get up to 800K with "normal" WD style MFM with
256 bytes per sector, and 512 byte sectors are a little tight)
The original ADFS had 16 sectors of 256 bytes per track. However, it appears
that more recent ADFS formats use 5 sectors of 1024 bytes. There are more
details here:
