What sort of lock?

The manuals should be available from tandberg.com.

That doesn't sound like a drive hardware error. Can you provide the 
QIC cartridge type? The Tandberg docs should list compatible media.

There are two issues with the NetBSD tape driver and QIC drives, AFAIR:
(1) Block size where the driver assumes fixed, the newer drives work 
better with variable.
(2) EOM, where the drive internally duplicates the EOD mark; since 
NetBSD writes two EOD marks, you end up with three on the tape. This 
can confuse later reads or appends.

Usually, these drives tend to last forever...

What do you get from an 'mt status /dev/nrst0', or an 'mt erase /dev/nrst0'?
