Your message raised several issues, some specific to Tandon or 3M, and some
general to floppy disk drives and media.

First, some of the hub ring reinforcements are too thick ( > 10 mils, I think),
so that the drive's clamp cannot seat properly.  On the other hand, without
the reinforced ring, you may get centering problems if the clamp is a bit loose,
particularly with 80 track drives.

Second, Tandon drives are, in general, not always the best.  Ask industry people,
even Tandon employees, and they will say that Tandon's busines reputation 
doesn't include superb quality.  So, you may have a drive problem.  this seems
to be a problem more with Tandon drives from the aftermarket than those supplied
directly by IBM with the PC.

Third, 3M media is good, when it's good.  Unfortnately, that too, isn't always.
For media, stick with Dysan, Verbatim, or Maxell, and you won't go wrong.

In short, to isolate your specific problem, try to reformat some Dysan or Ver-
batim reinforced ring diskettes on your drive, and then try to format your
3M diskettes on other Tandon or non-Tandon drives.

If this doesn't sound reassuring, then you're right.  A real opportunity for
someone with a good reputation to put his label on everything to reassure
the public of good quality.  (Hmnm, with a blue color ???)

Good luck,
