It may be victim blaming, but having 3 months of work and it only exists on one hard drive on one computer isn't very bright. He learned the hard way. I mean honestly, disk drives fail. PCs break. The code should never be in only one place regardless. Also, coming from VSS to Git has been, and still is, one of the hardest things I do as a windows dev. I hate git. It is non-intuitive and I have accidentally deleted my work before also, the difference being that I have it stored else where to get it too.
