To install testdisk on CentOS, Fedora, AlmaLinux, and Red Hat: To install testdisk on Ubuntu, Debian, and Linux Mint: This application isn’t likely to be installed on your Linux distro by default, so use the appropriate command below to install it. In this section of the guide, we’ll use the testdisk utility to perform recovery of deleted files. # dd if=/home/linuxconfig/backup_sdX.dd of=/dev/sdX

To recover a backup for *.dd file we simply reverse the process:.

# dd if=/dev/sdX of=/home/linuxconfig/backup_sdX.dd For this reason a backup of the entire partition: On the other hand creation of a low level backup with dd command gives us an opportunity for unlimited recovery attempts since we are always able to put the entire partition back bit by bit exactly as it was right after accidental file deletion.Īfter file deletion from a FAT file system, the actual file was not removed immediately, but the sectors on which the file resides is now available to be overwritten.

Any data written or file manipulation after accidental file removal will weaken our chances for deleted file recovery.

If for any reason you cannot unmount your device, remount it with read-only permissions:

dev/sdb and partition /dev/sdb2 respectively. dev/sdX or /dev/sdX2 we are in fact referring to the actual block device eg. For the sake of this tutorial we will refer to the our block device as /dev/sdX to avoid any accidental data damage by our readers when following the below text.
