DiskInternals Uneraser

DiskInternals Uneraser

Developer Website: https://www.diskinternals.com/uneraser/

  • 2023
Reviewed Version: 8.16

Overall Product Rating: 4.0

A program with a good basic wizard interface that can be switched to the Explorer style, very poor localization, an excellent file previewer, relatively strong demo restrictions, and very good recovery feature set.

Its strong points are: Two types of interfaces (wizard and Explorer), an excellent file previewer, excellent file system set (all file systems for Windows and Mac and most popular file systems for Linux and Unix), good raw file recovery, very good disk imaging capabilities, very good file recovery parameters, and very good logging.

Its weak points are:: relatively poor localization (only 3 interface languages), relatively strong demo restrictions (only file preview), No S.M.A.R.T. capabilities, poor file recovery performance, especially for damaged partitions (a total failure).
