I was just sent a link to a post that I thought I would share. Before I got into this line of work I had to bring my laptop in for repairs. After being assured that my data was safe I had my laptop returned with a completly rebuilt drive. I was never notified that my drive was even going to be reformated I was just SOL.
Anyway here is a another post obout similar experiences. This is why I always recommend backups and to hire a local pc tech that knows what he/she is doing.
