Some copy protection schemes add false C2 errors to discs to discourage copying. While causing data loss on Video CDs ( Mode 2 Form 2 ) and Audio CDs , individual C2 errors are correctable on data CDs (using Mode 1 and Mode 2 Form 1 ).
Burst errors include those due to disc material (defects of aluminum reflecting film, poor reflective index of transparent disc material), disc production (faults during disc forming and disc cutting etc.), disc handling (scratches – generally thin, radial and orthogonal to direction of recording) and variations in play-back mechanism.

In CP/M, attempting to read a floppy disk drive with the door open would hang until a disk was inserted and the disk drive door was closed (very early disk hardware did not send any kind of signal until a disk was spinning, and a timeout to detect the lack of signal required too much code on these tiny systems). Many users of CP/M became ...
A head crash is a hard-disk failure that occurs when a read–write head of a hard disk drive makes contact with its rotating platter, slashing its surface and permanently damaging its magnetic media. It is most often caused by a sudden severe motion of the disk, for example the jolt caused by dropping a laptop to the ground while it is ...
Media Degradation: Over time, storage media like optical discs or magnetic tapes can degrade, leading to read/write errors. Physical Damage: Physical shocks, drops, or other mechanical damage to the storage device can result in Medium Errors.

Compact disc bronzing, or CD bronzing, is a specific, uncommon variant of disc rot, a type of corrosion that affects the reflective layer of compact discs and renders them unreadable over time. The phenomenon was first reported by John McKelvey in the September/October 1994 issue of American Record Guide .
