Dear managers,
-------------------------------------------------------------------------------
My original question was:
Yesterday I inadvertently read a 120m DDS-2 tape containing dump
sessions using a TLZ06 drive using commands like "mt fsf 4" and
"restore -i". All I got is "I/O error". When I realized that a 120m
tape cannot be read with this drive, I tried a TLZ07 drive, getting
the same error message.
uerf reports a "Nonrecoverable medium _error" at the time of reading,
but no error at the time of the backup. Furthermore, my logfiles
report a successful backup.
My question is: could it be that the attempt of reading a 120m DDS-2
tape using a TLZ06 drive might have destroyed its content?

The simple answer:
The drive needed cleaning (could have guessed it, though last cleaning
was only about 20 days ago). Still <alan_at_nabeth.cxo.dec.com> pointed
out that indeed a TLZ09 drive might harm a 120 tape:
"Yes, I suspect it could. The 120m tapes are longer because they are
thinner. The TLZ06 is probably not designed to be sufficiently gentle
with the tape. This could damage it."
