Well, GParted, if I recall, does a couple checks to guess 'best' block size when cloning or moving a partition, but I'm really not sure how it does things when shrinking and shifting it sideways to a spot that overlaps with where it started... but based on the above, I would guess it really does do a bs of 512, or ar best, the cluster size of the file system it is moving (usually 4k), since it's moving the data stored there, not the whole partition, block for block. -- Poison [BLX] Joshua M.
