While it is true that 7-Data Card Recovery can undelete data accidentally lost from an external storage device, this tool can do much more than that, because it also works with local drives. The application has a nice graphical user interface. The search and recovery process works as a wizard which will guide you through the steps of selecting a drive, filtering and previewing results, and finally, deciding what to recover.
The real advantage of this recovery tool comes from its ability to deal with images, because it allows previewing them. Unfortunately, the application can only preview the contents of other file types as raw data. So if, let´s say, you want to recover a PDF file, you won’t really know what it will look like until you have actually recovered it.
In terms of effectiveness, the tool seemed to work fine with most file types, except those that had been overwritten with other data. Needless to say, it took quite a while to finally show the results, so a faster scanning would be preferable.
In general, 7-Data Card Recovery is an intuitive and effective application. However, it has a very specific purpose. Perhaps, you would like to purchase a similar tool with more features, let’s say, 7-Data Recovery Suite, by the same developer.
