1) check for FM / MFM / GCR recording on the first
side. You now know
density.
Oh, I was thinking of hard drives. Doing it on floppies would require
something akin to a Catweasel, or at least a more capable controller than that
of the PC, which for example will never read Commodore formats.

That's a start. There are LOTS of further
weirdities, many of which are
OS specific (such as an MS-DOS format where the Directory is NOT on track
0), or Various "Stand-alone BASIC" formats that have differing concepts of
disk center.
It would suffice to recognise the disk format, actually reading it is better
left to the proper OS/DOSDriver/computer.
