A data recovery tool loaded with features for advanced users
Pros & Cons:
TestDisk is an open-source software loaded with features. It has recovered 1GB in 83 seconds, a time which was beaten only by commercial software.
TestDisk is a cross-platform application which is pre-installed on a few Linux distro live CDs. It has many useful options like restoring DE type partitions which is very useful for Dell computers. It does not need to be installed and overall is very powerful.
On the down side it does not have a GUI and is targeted for more advanced users. It does have a good step-by-step guide for all recovery options. There are good detailed guides online, simply search Google for TestDisk Step by Step.
