To duplicate a disk to an identical one: dd if=/dev/hda of=/dev/hdc If they're on different computers dd if=/dev/hda | ssh remote.example.com dd of=/dev/hdc or ssh remote.example.com dd if=/dev/hda | dd of=/dev/hdcThere are other options, and you may want to use gzip or bzip2 to compress/uncompress data as it crosses the link.
Note that copying a drive in this manner while it's mounted rw isn't an especially good idea.
The target drive can actually be larger, and you can fiddle round with resizing tools if needs be.
You can also use tar, afio and lots of other programs to do file-by-file copies in these manners, and those allow you to change filesystems, and under some circumstances are quicker.
