I tried just blocksize 2043 with the same result.

Is there a way to manually define the tapetype from the command line and echo 
the results of each command?
Is there some kind of config command to check a configuration status?

On a whim, try "blocksize 2048".  'man amanda.conf' says that no modifier 
is necessary, so maybe it's confusing the parser somehow.  From a quick 
grep through my logs, I can't see the blocksize used reported anywhere.
