Fixed disk
Updated: 10/07/2019 by Computer Hope
Alternatively called a fixed disk drive, fixed media or fixed storage, a fixed disk is a hard drive inside the computer.
The word "fixed" is used because the drives are internal or in an enclosure that's not easily removed. Unlike a fixed disk, a removable disk such as a floppy diskette or compact disc are both easily inserted and removed from the computer.
Note
Although USB (universal serial bus) external hard drives can be easily moved from the computer, these drives are still called a fixed disk drive.
Tip
A fixed disk may also refer to the disk platter inside of a hard drive.
