Re: [K12OSN] Need Quick Help - Any way to do a low level, complete copy of my boot HD?



You are wanting the dd command or the ddrescue command.
Dd is standard but will likely choke on failed sectors.
Ddrescue will keep moving and retrying failed sectors until it suceeds or times out.

I'm going to keep googling, but I trust this list more than most Linux info I've seen. Like copying at the /dev/hda level. Copying partitions, etc.
