The MBR an FAT are totally seperate. BTW when you erase a file it only removes it from the primary FAT, leaving it intact on the secondary FAT (yes there are 2 of them in case the primary becomes corrupt).

End Threadjack.

Now my 2 cents worth, Delete that file an you might want to alert her that the file wasn't really deleted on her drive and explain how you know.
