Does this also include the new 4096 byte sectors that (some) of the new 1TB
drives have?
TBH to avoid such conundrums I would partition the darn thing using parted
with -a optimal option and then (s)tar/rsync the data into it. It will most
likely be faster than dd in any case as blank space and sparse files can be
easily taken care of with (s)tar/rsync.
