Guessing only.

Drives can generally use a fixed record (or block) size, set in the
hardware (possibly set by mt), or allow variably sized blocks set by
the writing application software.

Looks like your drive is saying it allows hardware settings from
1 byte to 16M.

Typically variable block size is set by giving a blocksize of zero.

Perhaps your drive does not accept a 0 as meaning variable but
considers it to be a real block size (not very useful ;).

Try using mt (maybe setblk or defsetblk) to set a variable block
size.  Alternatively, amanda typically uses 32kb records, so you
might try setting a default block size of 32768,
