TestDisk is a powerful free data recovery software. It 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 deleting your Partition Table). Partition table recovery using TestDisk is really easy. PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from Hard Disks and CDRom and lost pictures (thus, its Photo Recovery name) from digital camera memory. PhotoRec ignores the filesystem and goes after the underlying data, so it will still work even if your medias filesystem has been severely damaged or re-formatted.

TestDisk has features for both novices and experts. For those who know little or nothing about data recovery techniques, TestDisk can be used to collect detailed information about a non-booting drive which can then be sent to a tech for further analysis. Those more familiar with such procedures should find TestDisk a handy tool in performing onsite recovery.

There are other versions available at the authors site which support DOS, Linux, FreeBSD, NetBSD, OpenBSD, SunOS and MacOS.
