Hard disk drive. Hard drive redirects here. For other uses, see Hard drive (disambiguation). A hard disk drive (HDD), hard disk, hard drive or fixed disk is a data storage device used for storing and retrieving digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material.
Determine your hard drive's classification. Hard drives come in two main sizes--3.5 inch, and 2.5 inch--which are technical classifications that refer to the width of a hard drive's platter (the disk that stores your computer's memory), but not the full dimensions of the hard drive unit itself.
