I don't believe either tool resizes "on the fly" but they will make
a copy of your partitions for restoration to a new HD. You would need
to create your partitions on the new drive with Linux 'fdisk,' or
whatever low level Linux tool you prefer, and then use something to
copy the partition data from the old drive to the new. You may
actually be better off looking into 'rsync' used in local mode.

As far as I know there IS NO TOOL that does resize "on the fly" of
all the various partition types under Linux. IIRC PartitionMagic
supposedly will resize NTFS partitions but I haven't used any 'doze
utilities in four years since moving my business to all Linux, Unix
and OS/2 (eComStation) so I can't recommend it. I'm quite certain
that Symantec (bought out PowerQuest) has no interest in creating
tools that, or porting their tools to, run under Linux at this point
in time (other than some crappy AV stuff that I don't need). Their
loss is an opportunity for others to get it done.

You ask "why?". My answer is that 'dd' makes an EXACT bit for bit
copy of whatever you tell it to copy. No "resize on the fly" is
possible. I believe it is still considered "dangerous" to write to an
NTFS partition under Linux so to copy that data I would use something
booted from a 'doze utility diskette or CD like that software I
mentioned above. There may be reliable NTFS support in newer kernels
but I don't know about it if there is as I don't care about NTFS
support because I don't need or want it.
