I had a problem with write and read errors on tapes, mostly when information
was copied between them.
I was working as a consultant for a customer, and I checked the server. It
was a Compaq-server running Win2000. It had only a Compaq SmartArray
Controller which handled the internal raided disks, the two external
SDLT-tape stations and the library controller. We bought an Adaptec 29160
for control of the library and the tape drives. That fixed everything. No
more tape read or write errors.

All the tapes stay online in our library.  The library is housed in a data
center (in a very controlled environment).

Just FYI, I started auditing the tapes that showed errors and sure enough,
there have been around 100 files deleted off about 5 volumes (audit vol
XXXXXXX fix=yes).  The whole tape does not seem to be affected, just certain
files.  Could there be something that is causing file corruption when the
data is copied from the client machines?  Should we move the data off these
tapes and discard them, just to be sure?

thanks.
