Hmmm... too late!!
It's worse than i thought, the hard drive, which is what i wanted, (the information), is corrupt. I took the HDD out and plugged it into a similar system, hey presto, empty!
It seems that all the info is gone, all that remains is a few system files. Or even the windows folder contents - that is what it looks like.
How can this be!? All that survivees is the win folder contents?
Could this be a compatability issue with the hard drive and new pc i have shoved it into?
