Some file systems, such as Btrfs, HAMMER, ReFS, and ZFS, use internal data and metadata checksumming to detect silent data corruption. In addition, if a corruption is detected and the file system uses integrated RAID mechanisms that provide data redundancy, such file systems can also reconstruct corrupted data in a transparent way.

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 ...
File fixity is a digital preservation term referring to the property of a digital file being fixed, or unchanged. [1] Fixity checking is the process of verifying that a digital object has not been altered or corrupted. [2] During transfer, a repository may run a fixity check to ensure a transmitted file has not been altered en route.

Send image as an attachment: If you've sent an image in an email, but your recipient didn't receive it there may have been a problem with the way the file was sent.
Simple file verification (SFV) is a file format for storing CRC32 checksums of files to verify the integrity of files. SFV is used to verify that a file has not been corrupted, but it does not otherwise verify the file's authenticity. The .sfv file extension is usually used for SFV files. [1]
Data degradation is the gradual corruption of computer data due to an accumulation of non-critical failures in a data storage device.It is also referred to as data decay, data rot or bit rot. [1]
Torrent poisoning is intentionally sharing corrupt data or data with misleading, deceiving file names using the BitTorrent protocol.This practice of uploading fake torrents is sometimes carried out by anti-infringement organisations as an attempt to prevent the peer-to-peer (P2P) sharing of copyrighted content, and to gather the IP addresses of downloaders.
- Your computer's file manager will open. Find and select the file or image you'd like to attach. Click Open. The file or image will be attached below the body of the email. If you'd like to insert an image directly into the body of an email, check out the steps in the "Insert images into an email" section of this article.
