Which kernel are you running? If you're on a 3.2 kernel or you have a
recent pull of my git tree, you can try mount -o recovery.
My guess is that your machine went down pretty quickly after the loose
sata cable fell out? In that case mount -o recovery should work.
Otherwise we can work through the copy out recovery tools.
