To prove hardware problems, use a fresh tape, and do a

Hmm, looks like there's no amtapetype around... amanda-server-2.4.3,1
Too old or just not in that particular port?

In that time, it was called "tapetype", and was not installed
in the normal tree, I believe.  If you have the source tree around
look in the "tape*" directory.

But you can do just the same using dd:

   dd if=/dev/random of=/dev/st0 bs=32k

and count how many 32Kbyte blocks get on the tape.
Expect about 15000000000 / 32768 or about 457763 blocks.

Remember, it takes about 2-3 hours to fill a tape.

Multiple runs should result in an almost constant number of blocks
(plus/minus a few hundred).
