need more info:tape machine model, old and new tapes, when in the backup does
this fail(does it get half the data on tape first). my first guess i would
really suspect the tapes being different in some way. is this possible? i
dont have to format my hp surestore tapes ever. i also gave veritas exclusive
control of this device on installation.

You can check http://seer.support.veritas.com/docs/192216.htm for list of causes and
fixes for CRC errors. If it is only the new tapes, I'd double check that they are
compatible with the drive.

When you look in the device screen does the tape have a name? If not then
it is not initialized for the device.

I would try:

1. Ensure write protect is off on the tape.
2. Clean the drive.
3. Retension the tape. (You may not have a retension option depending on
your drive type.)
4. Erase the tape (Quick should be fine).
5. Retension again.

Most of the time I get a CRC error it is because of a dirty drive of a not
quite right tape. If I have a new tape I always do 3-4-5.
