For [[Data recovery (computers)]]:
'''Data recovery''' for computers is the process of recovering information which has been deleted, corrupted, or "lost." This can be attempted on any digital storage media, but the methods sometimes vary somewhat depending on the device.
==Logical damage==
Logical damage is probably the most common problem which requires recovery. There can be several causes for this kind of problem.
===Accidental deletion===
It is not uncommon for someone to have a problem where they accidentally delete one or more files. Many operating systems offer a "trash can" or "recycle bin" which holds deleted files in case someone changes their mind or deleted something by accident. However, even if a file is fully deleted, it is not immediately lost. Rather, the pointer to it in the file system is removed, and the space is marked as available.
===Overwritten data===
===Malfunction===
Especially when a storage device is getting worn out, it may eventually start having problems which prevent some date from being read or written.
===File system or partition table corruption===
==Physical damage==
