Yes, Recuva is very nice but I think he wants stuff that can recover data on a non-existing filesystem or whatever disaster you can think of. I doubt it make any sense for a private user to pay so much for emergency tools. Recuva or similar should be enough - rest is about backup, backup and more backup

Can easily be done free as well.
The time I used R-Studio was when I overclocked a hd-controller, years ago before pci speed got fixed. So disk was empty, no content. Using R-Studio in "raw" mode got my data back. All other tools I tried could not handle that situaiton. Well, point is not R-Studio is great but that I was an idiot - first with the braindead overclocking, next with not having backup of any kind. Recuva is always handy but there should not be a need for "forensic" tools - unless you make 100$ per hour saving other peoples data of course
