nope, the transport has rubber rollers that crack, and little rubber

That's the transport; but what are the shortcomings of the medium itself?
FWIW, I've got at least one DDS drive with rubber parts that have turned

Which brand & model drives, Chuck?
There appear to be different kinds of
material used for the rollers. For
instance,
with a 1999 OnStream DI30 (parallel port
30gb) ADR drive, it's a typical black
rubber roller like you'd see in many QIC
drives, and it's turned completely to goo.
But the SCSI version of the same drive
-- a 1999 SC30 -- has a red roller that
appears
to be maybe a silicone rubber.. and it's
still in perfect shape.
A 1996 SCSI Seagate DDS-1 DAT drive, on
the other hand, has what I guess is the
pinch roller. It's not gooey, but is
showing cracks.. Seems like a hard,
black rubber.
So at least one type of rubber
liquifies, and at least one type hardens
and cracks.
Very perplexing.
