Turn off AHCI? bad sectors?

[David Ehle <ehle@xxxxxxxxxxxxxxxxx>]

I'm getting the 7b bluescreen when trying to bring up an imaged XP system 
for recovery.

Looks like possible cause is AHCI on VM if missing from original hardware, 
or visa versa.

Or moving to sata hard drive from pata... which shouldn't be applicable 
here.

Also during an earlier recovery attempt I ran gparted from an ubuntu live 
CD on the VM/disk image.  It gave me a Warning bad sector message.... the 
disk image is a qcow image. How can it have a bad sector?

Thanks all!

David.
