Recuperación de Datos

There are many times that pople usually ask us if we can bring back their data from a hard disk (or any storage device), 'cause they "accidentally" deleted it. Uf!!! that really piss me off.

Surfing I've found a pair of free and open software that might help us to solve that:

• PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from hard disks, CD-ROMs, and lost pictures (thus the Photo Recovery name) from digital camera memory. PhotoRec ignores the file system and goes after the underlying data, so it will still work even if your media's file system has been severely damaged or reformatted. 
• 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. 

Both software can run trough a variety of operating systems, this is the most important issue because there are many programs that only run under Windows platforms consequently FAT and NTFS are only supported file systems, this is something that you don't have to experiment because supported file systems in Photorec and/or TestDisk are:

• BeFS ( 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 LUKS encrypted partition 
• Linux RAID md 0.9/1.0/1.1/1.2
  -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/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
