What is a hard disk drive?


Everything you need to know about computer hard drives

Hard disk drives are the main, and usually data storage hardware devices in a computer . Operating systems , software titles, and other files are stored on the hard disk drive.

Hard drives are sometimes referred to as “C drives” because Microsoft Windows defaults to the letter “C” in the initial partition of the primary hard drive on a computer .

While this is not a technically correct word to use, it is still common. For example, on some computers multiple drive characters (e.g., C, D, and E) represent the area between one or more hard drives. Hard disk drive is also known as HDD (for short), hard drive , hard disk , fixed drive , fixed disk and fixed disk drive .

Popular hard disk drive manufacturers

Some of the most popular hard drive manufacturers include Seagate, Western Digital, Hitachi, and Toshiba.

You can usually buy hard drives of these brands and in stores and online from other manufacturers, such as the company’s own sites as well as sites like Amazon.

Hard Disk Drive Physical Description

A hard drive is usually the size of a paperback book, but much heavier.

Hard disks as well as computers have threaded holes for easy mounting on the 3.5-inch drive bay. Mounting is possible in a larger 5.25-inch drive bay with an adapter. The hard drive is mounted so that the end of the connection faces inside the computer.

Hardadraye back to the motherboard is connected to a port for a cable there . The type of cable used ( SATA or PATA ) depends on the type of drive but is often included with the purchase of a hard drive. There is also a connection for power from the power supply here .

Most hard drives have jammer settings on the back end that can detect if the motherboard drive has more than one presence. These settings differ from drive to drive, so check with your hard drive manufacturer for details.

How hard drives work

Unlike unstable storage like RAM , a hard drive holds its data even when driven for this reason you can restart a computer , which is below HDD power, but still has access to all the data when back.

Inside the hard drive are sectors located on the tracks , which are stored on rotating platforms. These platters have magnetic heads that move with the hand of an actuator to read and write information on the drive.

Hard drive type

Computer hard drives are not the only type of hard drive, and SATA and PATA are the only ways they cannot connect to a computer. What’s more there are different sizes of hard drives, some very small and others rather large

For example, a normal flash drive also has a hard drive, but it does not spin like a traditional hard drive. Flash drives connect to computers with built-in solid state drives and USB .

Another USB hard drive is an external hard drive , basically a hard drive that is kept in its own case so that it is safe to exist outside the computer case. They usually interface with USB on the computer but some use FireWire or ESATAH.

An outer enclosure is a housing for an internal hard drive. You can use one if you want to convert an internal hard drive to an “external one”. They are also USB, FireWire, and so forth.

Holding capacity

The capacity of the hard disk drive is a huge factor that determines whether one can buy a particular device like a laptop or a phone. If the storage capacity is small, it means that it will fill files faster, but a drive that has a lot and a lot of storage that can handle a lot of data.

Choosing a hard drive based on how much it can save really depends on the opinion and the situation. If you need a tablet, for example, that can hold a lot of video, you’ll want to be sure to get a 64 GB one instead of an 8 GB one.

The same is true for computer hard drives. Will you save multiple HD videos or photos, or will most of your files be backed up online ? Choosing an offline, home storage option allows you to purchase an internal or external hard drive that supports a 500 GB vs. 4 TB. See Terabytes, Gigabytes, and Petabits: How Big are They? If you are not sure where the comparison of these units of measurement is.

Simple hard disk drive task

A simple task that you can do with a hard drive is to change the drive characters . This allows you to specify the drive using a different character. For example, the main hard drive is usually called the “C” drive and cannot be changed, but you may want to change the character of an external hard drive from “P” to “L” (or any other acceptable letter).

Before you save the file to install the operating system or drive format or drive partition format will do. When the OS is first installed, a new hard drive is usually formatted and a file system is provided; Otherwise a disk partitioning tool is a common way to manipulate the drive in this way.

When you are working with a broken hard drive, free defragmentation tools are available that help reduce fragmentation.

Since a hard drive is where all the data on a computer is actually stored, it is a common task to remove the data from the drive , such as before the hardware is sold or a new operating system is reinstalled. This is usually done with a data destruction program .

Hard disk drive troubleshooting

Your computer’s hard drive is used over, every time you are involved in reading or writing to disk data. This is normal, then, eventually runs into a problem with the device.

One of the most common problems is the hard drive that makes the noise , and the best way to fix a hard drive problem is to run a hard drive test .

Windows has a built-in tool called Chaddsk that can detect and fix various hard drive errors. You can run the graphical version of this tool on most versions of Windows .

Many free programs can test a hard drive for issues that may eventually require you to replace the drive . Some of them can measure performance like asking for some time .
