What Is a Fixed Disk? What Are the Different Types of It?

What Is a Fixed Disk?

What is a fixed disk? It is also known as a fixed storage or hard drive, a large-capacity magnetic storage device that is permanently installed inside a computer. These disks come in all shapes and sizes, but most work in the same basic way.

Fixed storage devices can be removed from the system for repairs, maintenance, upgrades, etc. But often this can’t be done without a toolkit opening up the system for physical access by an engineer.

How Does a Fixed Disk Work?

The inside of a fixed drive is the same in any size or configuration. An internal motor spins the very thin disk. These platters are covered with tiny magnetic regions, each with directional charges that gain traction as they spin, whose signals can be translated into meaningful data and orientation by a computer’s circuitry and motherboard.

Another internal motor runs one or more arms that move around the platter. The “read” arm reads the directional charge and sends the information out of the drive. The “write” arm, on the other hand, changes the directional charge to preserve and store new information on the platter. In different devices, the inside of one disk may look very different from another, but all these basic parts are usually there.

Different Types of Fixed Disk

The fixed disk can be divided into 4 types. They are listed below:

• Serial ATA (SATA)
• Parallel Advanced Technology Attachment (PATA)
• Solid State Drives (SSD)
• Small Computer System Interface (SCSI)

Uses of Fixed Disk

Almost every modern computer has one or more of these drives, which store all the information the computer holds, including operating system data, applications, documents, and photos. Any electronics with mass storage usually have these too, though usually on a smaller scale.

For example, the fixed disks in MP3 players are usually much smaller than those in desktop computers, but they usually work the same way and are very similar to each other, although one is necessarily smaller than the other. They’re also found in most digital video recorders, game consoles, and home media centers, and most modern smartphones also contain them.

The uses of a fixed disk can be generalized to below:

• Storage
• Backups
• Software Development
• Data and Information Sharing
• Gaming

Risks and Precautions

Fixed disks usually work best when they aren’t moving outwards, which in most conventional computers they aren’t – they sit on a desk, desk, or other fixed office space. However, as mobility increases, so does the risk of damage.

Tablets, smartphones, and portable music players are just a few examples of devices with fixed drives that move almost by design. Traditional disks don’t do well in these situations, and there’s always the risk of the read or write arm being pushed off track by too much jostling.

In most cases, though, easily removable devices also have protective casings and extra reinforcement around the drive to help prevent the disk from sliding or other damage.
