This can be a result of a few things:

• Wrong file type for the application. Please be sure the file type can be opened by your software.
• Wrong recovery method used. Confirm/check that the recovery app matches your media type.
• Data is corrupt at source. This means that the data is found in a corrupt state on the media, either from bad sectors, previously corrupt files, cross-linked sectors or, in the case of deleted files, the bitmap is missing and the files are not contiguous.

The only solution to try to remedy files that are corrupt, can’t be read or are unreadable is to try a different recovery method, and ensure that you’re recovering the right data (for example, using the Mac recovery app for mac formatted media).

If you have recovered deleted files and they are not usable then the problem is likely due to a missing bitmap (the bitmap tracks the location of fragmented files). Unfortunately a missing bitmap is a filesystem issue and beyond our control.

If you do have deleted files, before making a purchase of our software we ask that you obtain a free recovery activation to ensure the quality/results of the recovered data. Unusable data is unfortunately not covered by our money back guarantee.
