Does anyone know of any file recovery programs that can somehow tell you when you've deleted a file?

My KVM switch went crazy and as a result, I had two minutes of uncontrollable mouse activity that messed up my files and may have deleted some. Since I've got 15K of files on that disk, and there is no way I could remember all of them, and I was too lazy to catalogue the files, something that tells you when you've deleted a file would be a big help in accessing the damage.
