TestDisk is a powerful free data recovery program! 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).

PhotoRec is a File Recovery program designed to recover lost files; including video, documents and archives from Hard Disks, CDRom and lost pictures from digital camera memory (thus, its Photo Recovery name). PhotoRec ignores the filesystem and goes after the underlying data, so it can still find files even if your media's filesystem has been severely damaged or re-formatted (overwritten data, of course, can not be recovered).

You can download the latest version from https://www.cgsecurity.org/wiki/TestDisk_Download.

General Improvements

Both utilities are faster than previous versions: a better disk caching method is used in PhotoRec, and a better way to handle the sector scanning under TestDisk.

The Windows version of TestDisk and PhotoRec do not use the CYGWIN implementation of pread()/pwrite() (because a bug seems present).


TestDisk 6.7 now handles partitions created under Microsoft Vista. Traditionally partitions were created on cylinder boundaries. Under Vista, they are now independent of the disk geometry: These new partitions are aligned to a 1 MB boundary, and TestDisk can now handle that as well as the old cylinder boundaries. We have also changed the advanced menu items in light of these new Vista partitions.
