Hello guys! Same problem too!
I took her hard disk, put it in my PC, and suprisingly, i could read it..
I backed all the data into my exit had and passed it back to her.
Back home my friend plugged her had back into her drive and yet she couldn't do anything. So she reformatted it...and retrieved her data from my had. But I'm totally curious, why can i read it when she can't?

Thanks!
