What is the difference between Quick Recovery and Raw Recovery?

Quick Recovery searches for files and folders using file system information. It quickly scans catalog of the volumes and shows your files/folders .This is helpful in recovering data quickly when the volumes are not mounted (due to corruption).

Raw Recovery, on the other hand, is the signature-based recovery of data. In this process, the application searches for files based on specific signatures and when it gets a match, it classifies them accordingly in tree view. User can preview the data and save it at a desired location.

Raw Recovery may take more time but it is very useful in case of severe corruption.
