Yep, this is exactly what I have observed as well.

In some sense, itīs good to see the same thing is happening
on the opposite side of our planet as well, although I would
be happier if it would not happen at all, of course... ;-)

Right now, I have no idea, what this "IHC" stands for and
which component actually creates it. (It might also depend
on the machines ROM-BIOS. Whoīs the manufacturer of your
BIOS?)

Even if you remove and then re-insert them in the drive?

As far as I recall, this would indicate that the floppies
have not been formatted under DR-DOS.

The correct OEM format is "xxxxxy.y", that is "DRDOS7.0" would be
fine, but not "DRDOS 7.". But reading the high "7.0" version number
might confuse Windows as well. Since the DR-DOS BPB matches those
of PC DOS 3.3, the OEM string should really be "IBM  3.3", just as
it has been in older issues of DR DOS.

This should fix the problem. Formatting the floppy under MS-DOS
should also fix the problem. Does it?

(Well, itīs a while ago, when I investigated this, and I will have
to re-read my stuff to be absoletely sure about the effects...)

Greetings,

 Matthias
