The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
DMDE (DM Disk Editor and Data Recovery Software) is a data recovery and disk editing tool for hard drives and other storage media. It can work with physical devices, logical disks, disk images, as well as RAID-arrays and recovers files that have been accidentally deleted or lost due to other incidents. [1] [2] DMDE is available in various editions.
The core of Disk Drill is a Recovery Vault technology which allows to recover data from a medium that was secured by Recovery Vault beforehand. [5] [6] Recovery Vault runs as a background service and remembers all metadata and properties of the deleted data. Thus making it possible to restore deleted files with their original file names and ...
TestDisk is a free and open-source data recovery utility that helps users recover lost partitions or repair corrupted filesystems. [1] TestDisk can collect detailed information about a corrupted drive, which can then be sent to a technician for further analysis.
A disk editor is a computer program that allows its user to read, edit, and write raw data (at character or hexadecimal, byte-levels) on disk drives (e.g., hard disks, USB flash disks or removable media such as a floppy disks); as such, they are sometimes called sector editors, since the read/write routines built into the electronics of most ...
Data can sometimes be recovered from a broken hard drive. However, if the platters on a hard drive are damaged, such as by drilling a hole through the drive (and the platters inside), then the data can only theoretically be recovered by bit-by-bit analysis of each platter with advanced forensic technology.
Hetman Partition Recovery is a shareware program for recovery of deleted data from hard drive partitions and other storage media. The utility supports both functioning disks and damaged logical partitions and recovers data from both reformatted disks and disks which have had their file system changed from FAT to NTFS or vice versa.
The Gutmann method is an algorithm for securely erasing the contents of computer hard disk drives, such as files.Devised by Peter Gutmann and Colin Plumb and presented in the paper Secure Deletion of Data from Magnetic and Solid-State Memory in July 1996, it involved writing a series of 35 patterns over the region to be erased.
