You can use it to recover your boot sector form backup, fix FAT tables,fix your MFT, rebuild your boot sector, copy deleted files from partitions to recovery media, and find lost partitions in dozens of formats to help you locate your lost data. Not only can TestDisk used to collect detailed information about a non-booting drive, but also it can be a handy tool in performing onsite recovery.

It's a command line tool, so there's no GUI which is a major reason I haven't ranked it higher than some other data recovery softwares.

4.Restoration(Windows)

Restoration is a tiny,no-frills,portable recovery tool.You can use it in all versions of Windows and Windows file systems.Restoration is incredibly simple to recover files .There are no cryptic buttons or complicated file recovery procedures.Despite its tiny size,it performed just as well as the other nominees when tasked with restoring files from our test disks.

5.PhotoRec(Windows/Mac/Linux)

PhotoRec is a powerful software for safely and quickly copying your deleted files to another disk.It is a companion program to TestDisk,also devoid of a GUI,but likewise is quite powerful at file recovery.Many users distinctly prefer PhotoRec as a safer alternative when deep disk recovery isn’t necessary.It can recover files from optical driver,hard drives,and memory cards.Howecer,the greatest problem is that it’s very difficult to avoid recovring all deleted files at once.

I just don’t recommend making it your first pick. You can give PhotoRec a try if another data recovery software hasn’t worked.
