Very strange...
Can you read the new tape you just used?
Are there any errors in the Amanda debug logs or the system logs?
Are you sure you're actually using a tape and /dev/nsa0 didn't get converted
from a device to a plain file?
Does an mt command actually do something with the tape (can you rewind and
eject it)?
A dd of your tape shouldn't hurt it, but it's always safest to use the
write-protect tab in case you get
your if= and of= accidentally reversed.
If you rewind the tape, and dd a record off of it, what exactly do you get?
