This software is a free data recovery utility. TestDisk was primarily designed to help recover lost partitions and/or make non-booting disks bootable again when these symptoms are caused by faulty software, certain types of viruses or human error (such as accidentally erasing your Partition Table).

TestDisk is a free and useful program which queries the BIOS ( DOS/Win9x) or the OS ( Linux, FreeBSD) in order to find the Hard Disks and their characteristics ( LBA size and CHS geometry). TestDisk does a quick check of your disk´s structure and compares it with your Partition Table for entry errors. If the Partition Table has entry errors, TestDisk can repair them. If you have missing partitions or a completely empty Partition Table, TestDisk can search for partitions and create a new Table or even a new MBR if necessary.
