The adjacent image is a corrupted image file in which most of the information has been lost. Some types of malware may intentionally corrupt files as part of their payloads , usually by overwriting them with inoperative or garbage code, while a non-malicious virus may also unintentionally corrupt files when it accesses them.
Data damage can be caused when, for example, a file is written to a sector on the drive that has been damaged. This is the most common cause in a failing drive, meaning that data needs to be reconstructed to become readable. Corrupted documents can be recovered by several software methods or by manually reconstructing the document using a hex ...
Inability to read unknown file format; Failure. Power failure, resulting in data in volatile memory not being saved to permanent memory. Hardware failure, such as a head crash in a hard disk. A software crash or freeze, resulting in data not being saved. Software bugs or poor usability, such as not confirming a file delete command.
A file can become corrupted by a variety of ways: faulty storage media, errors in transmission, write errors during copying or moving, software bugs, and so on. Hash-based verification ensures that a file has not been corrupted by comparing the file's hash value to a previously calculated value. If these values match, the file is presumed to be ...

A more serious downside of autosaving is that it can prevent the player from completing a game if a save operation fails due to a sudden cessation of game operation, whether by a crash, freeze, or power loss of the gaming system (resulting in the save file being corrupted), or if a successful autosave preserves the effects of a game-breaking ...
The original photo is displayed first. In the next image, a single bit was changed from 0 to 1. In the next two images, two and three bits were flipped. On Linux systems, the binary difference between files can be revealed using the cmp command (e.g. cmp -b bitrot-original.jpg bitrot-1bit-changed.jpg).
When audio files are to be processed, either by further compression or for editing, it is desirable to work from an unchanged original (uncompressed or losslessly compressed). Processing of a lossily compressed file for some purpose usually produces a final result inferior to the creation of the same compressed file from an uncompressed original.
