Data corruption is the unintentional transformation of a file or the losing of info that usually occurs during reading or writing. The reason could be hardware or software failure, and due to this fact, a file can become partially or fully corrupted, so it will no longer function as it should as its bits will be scrambled or lacking. An image file, for instance, will no longer show an accurate image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. When this kind of an issue appears and it is not identified by the system or by an admin, the data will become corrupted silently and in case this happens on a drive which is a part of a RAID array where the info is synced between different drives, the corrupted file shall be duplicated on all other drives and the damage will be long term. Numerous popular file systems either do not feature real-time checks or do not have high quality ones that can detect a problem before the damage is done, so silent data corruption is a common matter on web hosting servers where huge amounts of data are stored.
