If you start making copies of your tapes for onsite storage, the copy
process could serve as your tape validation, and you wouldn't need to do
a VSTORE. It does seem that DDS drives need to be cleaned often. I
wonder if that is because the cleaning cartridges used in DDS drives
simply can't clean as thoroughly as solvent-based cleaning methods. On
the other hand, those drives record at an incredible density, so I can see
why the heads need to be very clean.

Yep, we do a VSTORE after each backup. We get errors about
<= 20 % of the time. I've on numerous occasions taken the tape
in question and restored the problem file(s)......no problem. Went
round & round with HPRC, and replaced the transports/electronics
a coupla times. We clean the drives each Monday morning and
(generally) use them only once a day Monday thru Saturday for
backups. They are DDSII drives and we use only one tape each
for the backups, giving 6 uses between cleaning. Our HP CE
says "clean 'em more often". I say "hogwash". Of course I
could be wrong....anyone else see this problem?
Drives are C1530B, OS is 5.0 PP 3, tapes are 90m HP Media
Recognition System and are almost 2 years old. That means
each tape has been used ummm...about 20 times. I don't think
its an age problem, as we've had these oddball messages since
the tapes and drives were new.
Back to the chase,
Jim Trudeau
