if you have an *identical* drive, you can use dd, something like:
    dd if=/dev/hda of=/dev/hdb

or, for a partion of *identical* size, something like:
    dd if=/dev/hda1 of=/dev/hdb1

(possibily adding a bs= option, IANA dd guru. Please read the manual!
dd can cause major, major data loss if not used properly. (One example
of this is the /. story of someone trying to copy a boot-sector from a
hard disc to a floppy and getting his if and of mixed up. No more boot
sector on either the floppy or the hard disc!) )
