TestDisk is a free and open-sourcedata recovery utility. It is primarily designed to help recover lost data storage 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 a partition table).TestDisk can be used to collect detailed information about a corrupted drive, which can then be sent to a technician for further analysis.

Supported partition table type[edit]
TestDisk recognizes the following disk partitioning:
- PC/Intel Partition Table (master boot record)
- Sun Solarisslice
- Xbox fixed partitioning scheme
It also handles non-partitioned media.
Partition recovery[edit]
TestDisk queries the BIOS or the operating system in order to find the data storage devices (hard disks, memory cards, …) and their characteristics (LBA size and CHS geometry).TestDisk can[1]
- Recover deleted partition
- Rebuild partition table
- Rewrite the Master boot record (MBR)
What Is Testdisk
TestDisk does a quick check of the disk's structure and compares it with the partition table for entry errors.Next, it searches for lost partitions[2][3] of these file systems:
- Be File System (BeOS)
- BSD disklabel (FreeBSD/OpenBSD/NetBSD)
- Cramfs, Compressed File System
- DOS/Windows FAT12, FAT16, and FAT32
- Windows exFAT
- HFS, HFS+ and HFSX, Hierarchical File System
- JFS, IBM's Journaled File System
- Linux ext2, ext3 and ext4
- Linux RAID
- RAID 1: mirroring
- RAID 4: striped array with parity device
- RAID 5: striped array with distributed parity information
- RAID 6: striped array with distributed dual redundancy information
- Linux Swap (versions 1 and 2)
- LVM and LVM2, Linux Logical Volume Manager
- Novell Storage Services (NSS)
- NTFS (Windows NT/2000/XP/2003/Vista/2008/7)
- ReiserFS 3.5, 3.6 and 4
- Sun Solaris i386 disklabel
- Unix File System UFS and UFS2 (Sun/BSD/…)
- XFS, SGI’s Journaled File System
However, it is up to the user to look over the list of possible partitions found by TestDisk and to select those that were being used just before the drive failed to boot or the partition(s) were lost. In some cases, especially after initiating a detailed search for lost partitions,TestDisk may show remnants of partitions that had been deleted and overwritten long ago.
A step-by-step guide[4] explains how to use this software. TestDisk can be used in computer forensics procedure,[5] it supports the EWF file format used by EnCase.
Filesystem repair[edit]
TestDisk can deal with some specific logical filesystem corruption:[6]
- File Allocation Table, FAT[7]
- 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
- FAT12 and FAT16
- exFAT
- Restore the boot sector using its backup
- NTFS[8]
- 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[9]
- HFS+
- Restore the boot sector using its backup
File recovery[edit]
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[10]
- NTFS file undelete[11]
- exFAT file undelete
- ext2 file undelete[12]
