TestDisk is a powerful hard disk repair tool to help users recover lost data and repair hard drives that cannot be started. It is very easy to use Testdisk to restore partition tables.

Install TestDisk (PhotoRec) in the Linux system

Execute the following related commands on the system to install TestDisk:

-On Debian/Ubuntu/Linux Mint-$sudo apt-get install testdisk- On CentOS/RHEL/Fedora-$sudo yum install testdisk- On Fedora 22 +-$sudo dnf install testdisk- On Arch Linux-$pacman-S testdisk- On Gentoo-$emerge testdisk

If you don't have this installation package in your Linux system repository, you can download it here and run it in Live CD.

This installation package can also be found in emergency repair CD tools, such as Gparted LiveCD, Parted Magic, Ubuntu Boot CD, Ubuntu-Rescue-Remix, and other tools.

After the installation is complete, open a text window with the permissions of the root account, launch PhotoRec, and specify the partition of the deleted file:

$sudo photorec / dev/sda3

You will see the following interface:

Select a directory to store the files to be restored, and when you are finished, press C to continue. Select directories for different partitions to avoid overwriting deleted files when more files are stored in this partition.

Press the left arrow to return to the root partition.

Select the directory where you want to save the recovery file

The following figure shows the deleted files of the specified type being restored. You can press enter to stop the operation.

Note: during the recovery process, your system will become very slow and is likely to get stuck for a while. Please wait patiently until the recovery is complete.

Finally, the Photorec tool will show the number of files recovered and the path to which they were saved.

Summary of Linux file recovery

By default, recovered files will be saved with root account permissions, so you need to open the File Manager to access these files with elevated permissions.

Use the following command (specify your file manager):

$gksudo nemo or $gksudo nautilus for more information, visit the PhotoRec website: http://www.cgsecurity.org/wiki/PhotoRec.
