I am not sure I can parse your sentence. But:
# blockdev --getbsz /dev/loop1 0 # dd if=/dev/zero of=tenbl bs=1024 count=10 10+0 records in 10+0 records out # losetup /dev/loop1 tenbl # blockdev --getbsz /dev/loop1 4096 # dd if=/dev/zero of=/dev/loop1 bs=1024 count=10 dd: writing `/dev/loop1': No space left on device 9+0 records in 8+0 records out # blockdev --setbsz 2048 /dev/loop1 # blockdev --getbsz /dev/loop1 2048 # dd if=/dev/zero of=/dev/loop1 bs=1024 count=10 10+0 records in 10+0 records out #
