dd if=/dev/zero of=/dev/rstwhatever ibs=256k obs=8k (or multiples of 8k)

as an EXAbyte writes 8*1k simultaneously;
furthermore it speeds up later writing if the tape has been written over once :)
(the EXA does faulty-spots-marking; with us (Europe) 2.1 GByte will always fit,
 2.3 GByte many times)
