Top data recovery tools for linux

Sadly sometimes we lose precious information by formatting a wrong partition or disk, due to hardware problems or transference errors. Luckily we have many free tools available to recover our lost data. This is not a tutorial but a fast review on the most popular free data recovery software available for Linux.

DDrescue

Is a command line tool which tries to recover good sectors from damaged devices or partitions. It requires minimal dedication by the user, the whole process is automated and it even deals with errors without interacting with the user. It does not overwrite bad sectors. If you have different sources from the lost data DDrescue knows how to merge good sectors from different copies to recover your data.You can download DDrescue from: http://www.gnu.org/software/ddrescue/ddrescue.html

To install it on Debian or Ubuntu users can run:

apt install gddrescue -y

Then run:

ddrescue

GParted

GParted is an old solution, if I’m not wrong it is among the first graphical alternatives to carry out partitioning on Linux, very similar to PartitionMagic for Windows devices. It is the most user friendly alternative because of it’s simple graphical interface. It is available for Linux, Macintosh and Windows devices.

To install Gparted Debian and Ubuntu users can run:

apt install gparted -y

Conclusion:

The Open Source community offers many free alternatives to deal with problematic storage situations.  Anything from partition problems to physical broken disks can be treated with the proper software and patience. DDrescue was the first listed tool because of its simplicity and lack of dependency on the user, you can leave it working and forget about the task, or stop and restart the process from the paused step.
