TestDisk is a powerful free data recovery utility. 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
PhotoRec is file data recovery software designed to recover lost pictures (Photo Recovery) from digital camera memory and lost files including video, documents and archives from Hard Disks and CDRom. PhotoRec ignores the filesystem and goes after the underlying data, so it´ll work even if your media´s filesystem is severely damaged or formatted. PhotoRec is safe to use, it will never attempt to write to the drive or memory support you are about to recover from. Recovered files are instead written in the directory from where you are running the PhotoRec program.
System Requirements:
- Operating System: Windows All Version
- Language: English-US
- License: Open Source
- Author: Christophe GRENIER
Changelog:
# General Improvements:
fidentify, a little utility sharing PhotoRec signature database, is now build by default. It identifies the type of data contained in a file and reports the extension as seen by PhotoRec. It is similar to the Unix file command. Add compatibility with
- libewf 20110312
- ncurses 5.8
- ntfs-3g
Fix detection of Encase 6 .ewf files
# TestDisk:
- Convert the directory name when it can't be created (Fix for Windows/Cygwin version)
- Better HPA/DCO detection: handle the case where native_max is null.
Image Creation
is now faster tahn previous version when there are bad sectors
- List and copy files from exFAT filesystem
- Improved NTFS undelete interface
# PhotoRec
- PhotoRec checks for EFBIG (file too large) error when writing files. It's usefull to avoid erronous message about "no free space available" when recovering to a FAT filesystem.
- Recover files from exFAT unallocated space
- Use doc/xls/ppt title to name recovered Office document, use first filename in zip archive...
- Possibility to add your own extension/custom signature to PhotoRec
- Generated a report.xml file using Digital Forensics XML
