Can you copy
an entire disk using the UNIX dd
command from a smaller
disc to
a larger one and retain the capacity of the larger
drive?
Not without other tools, at least on any OS I
work with. dd
overwrites the filesystem's index, superblock, etc,
so even if the
partition is bigger than the filesystem, you can't
use it.
dd also seems to have some implementation-specifics
baked into it. On Solaris I was completely unable to
transfer a raw VMS disk image from one drive to
another (identical) one using dd; however the same
transfer worked correctly under Linux.
