To rule out a bad tape:
Before removing the tape from the drive use smartctl -A
/dev/sg(generic of drive) to count the corrected errors
You can do this whilst the tape is being written to. If the
numbers are increasing rapidly, either the tape or the drive is
dirty.
If it keeps occuring on other tapes, after running a cleaning tape
then the drive is dirty and will need replacing under your support
contract.
Qualstar-sourced tapes are all run through a cleaning machine
before repackaging.
Other tapes sometimes come with a bonus of various contamination
types (I've had this happen) and drives themselves are susceptable
to picking up gunk if it's in the local atmosphere - it gets worse
if humidity is low.
A clean tape and clean drive will generate almost zero errors.
Once contaminated the numbers just keep increasing.
