I may want to add some additional testing steps to the original how-to so people fully test myth before going ahead and adding sda3 to lvm. That way if there is troubles they can back out of the lvm procedure.

I have used utilities at work that wipe the disk completely by writing zeroes to the entire drive. GWSCAN is one that I have used in the past. Maybe a disk wipe on bad disk will correct the issues you are having. That is unless this is your drive with root on it.
