Simon,

It could be bad tapes, but it also could be bad tape drives, or bad software 
even.

Are the errors only with one or a few tapes, or all tapes.

So the questions to start with.

What tape drives are you usings? What is the firmware level? Interfaces? 
Switches? Drivers?
What tape carts are you using, any stats on the  tapes such as the total 
number of mounts for each.

What are you seeing in the os and netbackup error logs. For netbackup error 
logs look at the netbackup troubleshooting book. Look at the bptm logs.
