Hi
That is why HDOS for H8/89 had volume numbers assigned
to each disk. If the user was faithful and used a new number
for each formatting, one was protected against overwriting,
or so I'm told.
Most didn't do this and trashed there disk.
I'd always thought that it wouldn't have hurt to use one more buffer
and check to see if the disk in the drive had a matching dir and
allocation table.
Another way might be to keep a random number, create from
a hash of the information on the disk, that would need to be read
before writing.
