Occasionally there is too much filesystem damage to allow a file to be completely intact when recovered. This is known to happen on a rare occasion and is usually caused by easily preventable circumstances.

When a drive begins to fail, writing to the drive may overwrite portions of the file system, causing the file system to point to files in the wrong locations on the drive. When this happens, VirtualLab™ looks to where the file is supposed to be and recovers the data there. It has no way of determining if the data at that location is valid or invalid.

To prevent this from happening, you should attempt to preview files after the recovery scan to make sure that the data is valid. If a few picture or movie files are able to be previewed successfully, then chances are the rest of your data is fine. However, if previewing most of the picture or movie files fails, there is a high chance that the recovered data will end up being corrupted.

If all of the previewing fails, try performing a Recover Initialized/Erased Drive recovery and enable the File Type scan by clicking ‘Yes’ when prompted. Then select the files you want to recover by type in the following dialog. This will cause VirtualLab to search for catalog trees AND search for files by using file signatures which always recover correct file data, but do not always able to recover the file name.

Do not give up! A professional data recovery service such as BinaryBiz may still be able to recover that data.
