TestDisk is 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 a Partition Table). Partition table recovery using TestDisk is really easy.

• It also handles non-partitioned media. 

Filesystem repair

• TestDisk can deal with some specific logical filesystem corruption:
• File Allocation Table, FAT
• FAT12 and FAT16
• Find filesystem parameters to rewrite a valid boot sector
• Use the two copies of the FAT to rewrite a coherent version

FAT32

• Find filesystem parameters to rewrite a valid boot sector
• Restore the boot sector using its backup
• Use the two copies of the FAT to rewrite a coherent version

exFAT

• Restore the boot sector using its backup

NTFS

• Find filesystem parameters to rewrite a valid boot sector
• Restore the boot sector using its backup
• Restore the Master File Table (MFT) from its backup

Extended file systems, ext2, ext3 and ext4

• Find backup superblock location to assist fsck

HFS+

• Restore the boot sector using its backup

File recovery

When a file is deleted, the list of disk clusters occupied by the file is erased, marking those sectors available for use by other files created or modified thereafter. If the file wasn't fragmented and the clusters haven't been reused, TestDisk can recover the deleted file:

• FAT file undelete
• NTFS file undelete
• exFAT file undelete
• ext2 file undelete
