I'm not sure I understand. Is the drive doing anything? Does the
machine/card normally hang?
I would expect the blocksize change to go pretty quickly, unless the drive
automatically does a format or something similar when you change the
blocksize. (With other drives, you change the blocksize and then format.)
Can you tell if the drive is doing anything?
The other problem you may have with this is that if the drive does format
itself when you change the blocksize, the timeout for the mode select is
likely too short. In fact, the default timeout for generic SCSI commands
like the one you issued is 5 seconds, which is way too short for a format.
