yeah, virus or he formatted his harddrive incorrectly when installed. I've been working with windows since they first rolled the product out. The only times I have seen data dump like this is virus, incorrect formatting or bad sectors on the hd. If it is formatted incorrectly, there is a good possibility that this still exists but it has justt been renamed something like #0000000000000af or some equally meaningless nonsense.
If you are using norton or macafee, you can bet you have infected files that neither of thise programs even noticed.
I would get a copy of avast or kaspersky and do an intensive virus search.
Unless you already have reason to believe you improperly formatted your drive.

Other than that, human error and you only think you saved your work.
