TestDisk & PhotoRec description

 A tool to check and undelete partitions

TestDisk 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 erasing your Partition Table).

TestDisk is a free and useful program which queries the BIOS ( DOS/Win9x) or the OS ( Linux, FreeBSD) in order to find the Hard Disks and their characteristics ( LBA size and CHS geometry). TestDisk does a quick check of your disk's structure and compares it with your Partition Table for entry errors.

If the Partition Table has entry errors, TestDisk can repair them. If you have missing partitions or a completely empty Partition Table, TestDisk can search for partitions and create a new Table or even a new MBR if necessary.

However, it's up to the user to look over the list of possible partitions found by TestDisk and to select the one(s) which 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 partition data which is simply from the remnants of a partition that had been deleted and overwritten long ago.

TestDisk has features for both novices and experts. For those who know little or nothing about data recovery techniques, the command line parameters /log and /debug 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.

TestDisk can find lost partitions for all of these file systems:

· BeFS ( BeOS )

· BSD disklabel ( FreeBSD/OpenBSD/NetBSD )

· CramFS, Compressed File System

· DOS/Windows FAT12, FAT16 and FAT32

· HFS and HFS+, Hierarchical File System

· JFS, IBM's Journaled File System

· Linux Ext2 and Ext3

· 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

· Mac partition map

· Novell Storage Services NSS

· NTFS ( Windows NT/2K/XP/2003 )

· 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
What's New in This Release: [ read full changelog ]

General Improvements:

· The log file generated by the Windows version (cygwin) reports bad sectors in a more readable fashion, example

· ReadFile Data error (cyclic redundancy check).

· As openssl isn't used, don't link with this cryptographic library (Debian tries to avoid mixing GPL code and openssl)

TestDisk:

Improvements:

· testdisk /list now displays the disk model, serial number, firmware version and hpa or dco presence if detected

· Recover WBFS (Wii Backup File System) partition

· Make FAT RebuildBS works when there is a single FAT table

· Interface: Display the partition table type if autodetected

· Interface: modified warning about mismatching geometry between FAT or NTFS boot sector and HD geometry information (Debian #651756)

· Interface: Remove "Allow partial last cylinder" option

Bug fixes:

· Fix crc in EFI backup GPT

· Rewrote how TestDisk aligns partition on cylinder or 1MB boundary. It avoids to create partition entry where the partition ends after the end of the disk.
