Thanks Jeff ..I will indeed make a Frankenstein Disk ..once I have a working image to write back.
I am also bidding on a used Samsung Samsung SFD-321B drive as this is the drive used by Jim and others to archive tricky floppies.
It will of course be thoroughly cleaned before use ..and will hopefully eliminate the current drive I'm using as a possible source of error.
I have inspected the disk surface by eye and see no issues ..but as Jim says ..this is not conclusive ..and could well be the disk not turning freely inside its case.
