I have a 500GB Sata drive about 15% used I would like to make an exact copy of too another Sata 500GB drive as a spare. That way if something happens to the one in service I can plug in the spare quickly and restore one of the weekly backups without reinstalling the entire OS and all the little tweaks of setup on this mail/web server. How do I do this? That is make an exact bootable copy of a linux drive. Its running Centos 4.6 if that matters. Matt
