Test results and conclusions

Tested software

The following unerase tools were tested:

Test results

With a small number of deleted files, all the test results were indentical. All the files were recovered, and the difference in speed was negligible.

Note 1

Speed was tested with two million deleted files.

Note 2

It is impossible to estimate speed or recovery quality because the tool displayed an error "out of memory" at 43% of the scan, so we do not recommend it when you need to unerase a large number of files.


Typically, if you need to recover a few deleted files, all unerase tools get the same result - recover files with the same efficiency and speed. The choice of a recovery tool depends on: price, ease of use, and tool's interface. In case of deletion of a large number of files (starting with tens of thousands), unerase becomes similar to unformat. When choosing a recovery tool you should take into account what recovery capabilities a particular unerase program has. For example, Recover My Files cannot handle two million of deleted files displaying an "out of memory" error. Recuva has a limit of about six million deleted files on NTFS and just hung during the scan requiring a hard reboot of the system.
