Hi all,

I have also some fresh experience with diskette OEM labels under
Windows.

From my experiences (Win 98 SE, Award BIOS), Windows overwrite
OEM label with "*****IHC" not only on DR-DOS formatted diskettes
("DRDOS  7"), but also on (at least some) new factory-formatted
diskettes ("IBM  3.3").
After the OEM label gets garbaged, the diskettes continue to
work properly in Windows DOS box in most cases (but yesterday,
in fact, I got read error for the first(?) time).
I don't understand it at all.
