Odd.  That wasn't my experience here Jon.

If I did a 'dd if=/dev/nst0 of=scratch', if the tape had been set for 
32768 blocksize, then thats the size of a scratch file I got, without 
telling dd the bs=32768.  If that tape had not been set for 32768, 
then I assume the default must have been 512, and thats the size of 
the scratch file I'd get.

When I was converting my tapes, I'd read out the label block, and use 
the syntax to make dd pad it on out to 32768 on the write back, IIRC 
thats a -s or something.

Maybe there's different logic in other platforms dd?  I wouldn't know.
