Recover Lost Data by StompSoft
This program performs scans pretty quickly. It is easy to use and the tech support is very helpful and quick to respond. This software has the ability to find and recover a lot of lost programs. Overall it's a good program if you want to recover files that were deleted by accident, because of a power outage, virus, etc. However you might want to look elsewhere if your files were lost due to a more serious problem
Mediatools Professional by ProSoft Engineering
This program is the most loaded. It scans you disk quickly and is very easy to use. It has the ability to recover almost all the files that you lost, no matter how badly they are damaged. It also has great customer support. However, because of the price, I would only reccomend buying this program if the files you are looking for a damaged very badly, or if you hard disk is in terrible shape.
