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.

TestDisk can

Fix partition table, recover deleted partition

Recover FAT32 boot sector from its backup

Rebuild FAT12/FAT16/FAT32 boot sector

Fix FAT tables

Rebuild NTFS boot sector

Recover NTFS boot sector from its backup

Fix MFT using MFT mirror

Locate ext2/ext3 Backup SuperBlock

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.

Latest Changes:

TestDisk and PhotoRec will be easier to use for users working on disk or partition image: the partition table type is automaticaly detected and selected

In TestDisk 6.8, HFS partition detection has been improved to avoid false positive

TestDisk now records the potential NTFS partition location from $MFT and $MFTMirr

Location while rebuilding NTFS boot sector

A few bugs have been fixed in PhotoRec 6.8, .dta and .spss (statistical

Analysis) file format support have been added and .7z, .cab, .rar and

.tar recovery have been improved. Recovery of fragmented JPEG by brute-force

Have been improved but as it's very time consuming without being 100%

Reliable, this option is not enable by default
