Disk and drivesDISK

A disk refers to magnetic media, such as a floppy disk, the disk in your computer's hard drive, A round plate on which data can be encoded, and an external hard drive. Disks are always rewritable unless intentionally locked or write-protected. You can easily partition a disk into several smaller volumes, too. Disks are usually sealed inside a metal or plastic casing.
