[LUNI] What's the best way to transfer a large amount of data between hard drives?

[Samir Faci]

dd is overkill for transferring data.  You'll copy used and unused bits
from the hard drive.

I've used ssh/tar before if you want to do ssh (which slows the transfer)
look at this page:  http://ultra.ap.krakow.pl/~bar/DOC/ssh_backup.html

rsync is probably the best, I'd say though I haven't used it much.
