Also, my impression is that 1.2 MB HD floppies have a magnetic surface
that is a little lighter, more metallic looking than the DD floppies?
Unfortunately I don't have a single 5.25" HD disk to check.

I always thought disks once formatted on a PC were forever useless on
other (C64/Amiga) systems, even if the disk was of the right capacity.
I don't know why, but I experienced R/W errors in particular on 3.5" DD
disks once used on a PC but later reformatted on Amiga. Other disks from
the same package would work flawless. If this is not only my personal
experience, some special bulk erasing measures may have to be taken to
successfully reuse the disks Michael found, if they are suitable at all.
