'''Hard disks''' are magnetized modules of [[computer]] memory.  Magnetization is used to store compartmentalized information in [[binary]] code, by turning the magnetized piece of the drive "on" or "off."  A single hard disk will contain billions of these individual points of information ([[bits]]) aggregating to larger amounts of storage, such as ([[bytes]]) or megabytes.  Hard disks are vulnerable to [[magnetic field|magnetic fields]].

'''Hard disks''' are mechanical forms of [[computer]] memory consisting of spinning platters of magnetic materials inside a sealed unit.  Magnetization is used to store compartmentalized information in [[binary]] code, by turning the magnetized piece of the drive "on" or "off."  A single hard disk will contain billions of these individual points of information ([[bits]]) aggregating to larger amounts of storage, such as ([[bytes]]) or megabytes.  Hard disks are vulnerable to [[magnetic field|magnetic fields]].
