Hello. I tried this, also, but with a similar effect. It think the HP SureStore 40x6i (DDS-4) isn't a ancient tape drive, the PC-recommended and factory default setting for this expensive DAT autoloader is 1024 bytes per block. I switched via mt blocksize 0 to variable blocksize, but then writing to the tape took much longer. -- MfG O.
