TestDisk can recover deleted files especially if the file was not fragmented and the clusters have not been reused. There are two file recovery mechanisms in the TestDisk package: [2] TestDisk proper uses knowledge of the filesystem structure to perform "undelete". PhotoRec is a "file carver". It does not need any knowledge of the file system ...
Foremost is a forensic data recovery program for Linux that recovers files using their headers, footers, and data structures through a process known as file carving. [3] Although written for law enforcement use, the program and its source code are freely available and can be used as a general data recovery tool. [2]
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
In MS-DOS, one can use the undelete command. In MS-DOS the "deleted" files are not really deleted, but only marked as deleted—so they could be undeleted during some time, until the disk blocks they used are eventually taken up by other files. This is how data recovery programs work, by scanning for files that have been marked as deleted.
Recovery of fragmented files (after the first fragment) is therefore not normally possible by automatic processes, only by manual examination of each (unused) block of the disk. This requires detailed knowledge of the file system, as well as the binary format of the file type being recovered, and is therefore only done by recovery specialists ...
Search and Recover can rescue crucial work and cherished memories you thought were gone forever. It's fast and easy to use, and even data lost years ago can be recovered.
Once this block size is known, PhotoRec reads the media block by block (or cluster by cluster). Each block is checked against a signature database; which comes with the program and has been growing in the type of files it can recover ever since PhotoRec's first version came out. It is a common data recovery method called file carving.
