Shane,
PM me your e-mail address and I'll send you the program and as much documentation as I got around to writing.
Basically, when you "delete" something of a hard disc, the 1's and 0's don't actually get wiped out, they just have a flag set next to them that says "ignore me" and will eventually get over written. Even if you've over written a few times, it is sometimes possible to recover the originals files.
However, after 13 months, you might be pushing it if you often install and delete files and data. If you "Really" want to recover something you've lost, the SpinRite program, especially SpinRite 6, is really good. But pretty expensive. However, depending on the data you've lost, it can often be worth it.
