Hi guys, I have two HDs that are exactly the same model and capacity: /dev/sda, and /dev/sdb. I wish to make /dev/sdb an EXACT CARBON COPY of /dev/sda. Is there some command to do that? Thank you! _________________ Anapnea, the open Gentoo shell server: http://anapnea.net

Code:

dd if=/dev/sda of=/dev/sdb

Both drives have to be unmounted for this to work.

Or ddrescue if there are expected to be bad sectors on the source hard drive.
