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.

Darik's Boot and Nuke, also known as DBAN / ˈ d iː b æ n /, is a free and open-source project hosted on SourceForge. [2] The program is designed to securely erase a hard disk until its data is permanently removed and no longer recoverable, which is achieved by overwriting the data with pseudorandom numbers generated by Mersenne Twister or ISAAC.
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.
For example, if Windows Disk Management (Windows 2000/XP, etc.) is used to delete a partition, it will overwrite the first sector (relative sector 0) of the partition before removing it. It still may be possible to restore a FAT or NTFS partition if a backup boot sector is available.
