Photo Recovery Guru is a tool that allows you to recover deleted and lost photos and movies from your digital camera, mobile phone, disk, or other device type.
It works to recover files that have been accidentally deleted, memory cards that have become corrupted, and even memory cards that have been reformatted.
It is well integrated with Mac OS X and will present you the list of your deleted files in an interface that is very similar that the Mac OS X Finder presents your regular files in, complete with thumbnail previews.
It is completely risk-free. It opens your device in read-only mode and will never write to it, and therefore if you have some critical data that you want to recover you can rest assured that the data will remain safely in the same state as when you started.
Some features:
⁃ Easy to use
⁃ Enhanced for Lion
⁃ Media rich and intuitive interface
⁃ Tolerant of physically faulty media
⁃ Content-based scanning to be filesystem independent
