What is a fixed disk?

A fixed disk, also known as a hard disk drive (HDD), is a non-removable data storage device that is typically found inside a computer or external storage enclosure. It consists of one or more rigid platters coated with magnetic material that store data on spinning disks.

Fixed disks can have various storage capacities, typically ranging from several hundred gigabytes to multiple terabytes. They are used to store operating systems, applications, and personal files such as documents, photos, videos, and music.

Fixed disks are connected to a computer via a SATA, IDE, or SCSI interface, and data is read and written to the disk using a read/write head that moves across the spinning platters. The data on a fixed disk is stored in binary format as a series of magnetic particles that represent 0s and 1s.

Fixed disks have a relatively high storage capacity and are known for their reliability and long lifespan. However, they can be sensitive to physical shock and damage, so it is important to handle them carefully to prevent data loss.
