By • Technical Writer and Editor • Associate Site Editor What is a hard disk drive? A computer hard disk drive (HDD) is a non-volatile data storage device. Non-volatile refers to storage devices that maintain stored data when turned off. All computers need a storage device, and HDDs are just one example of a type of storage device. HDDs are usually installed inside desktop computers, mobile devices, consumer electronics and enterprise storage More specifically, hard disk drives control the reading and writing of the hard disk that provides data storage. HDDs are used either as the primary or A hard disk drive -- often shortened to hard drive -- and hard disk are not the same things, but they are packaged as a unit and either term can refer to the whole unit. Why do computers need hard disks? Storage devices like hard disks are needed to install operating systems, programs and additional storage devices, and to save documents. Without devices like HDDs that can retain data after they have been turned off, computer users would not be able to store programs or save files or documents to their computers. This is why every computer needs at least one storage device to permanently hold data as long as it is needed. How do hard disk drives work? Most basic hard drives consist of several disk platters -- a circular disk made of either aluminum, glass or ceramic -- that are positioned around a spindle inside a sealed chamber. The platter spins with a motor that is connected to the ...

If your PC is running low on free space, you might not be able to install important Windows updates, and your PC’s performance may be affected. Here are some ways to free up space so you can keep your PC up to date and running smoothly. These suggestions are listed in order, so start with the first one, see if that helps, and then continue to the next one if it doesn't. To check the total disk space left on your Windows 11 device, select File Explorer from the taskbar, and then select This PC on the left. The available space on your drive will appear under Devices and drives. If you don't want to use Storage Sense, Cleanup recommendations can help you identify and clean up temporary files and system files from your device. • Select Start > Settings > System > Storage > Cleanup recommendations. • Review each of the categories, including Temporary files, Large or unused files, Files synced to the cloud, and Unused apps, and select the items you'd like to remove. Windows will suggest files for you and show the amount of space you'll save when you remove those items. • After you've selected items to remove, select the Clean up button for each section. Note: If it’s been fewer than 10 days since you upgraded to Windows 10, your previous version of Windows will be listed as a system file you can delete. If you need to free up drive space, you can delete it, but keep in mind that you'll be deleting your Windows.old folder, which contains files that give you the option to go back ...

Table of Contents • • • • • • • Introduction Have you ever heard of the term HDD and are curious what it means? HDD, which stands for Hard Disk Drive, is one of the main components in computers and data storage devices. This article will provide an in-depth HDD full form, including their meaning, functions, how they work, the differences from SSDs, as well as some tips for managing and optimizing your HDD usage. Let’s start by explaining the definition of HDD full form in detail. What is HDD? Explaining Understanding and Definition of HDD. A Hard Disk Drive (HDD) is a data storage device used to store digital information in the form of files, documents, images, videos and applications on computers and other electronic devices. HDD consists of a magnetic disk that rotates at high speed and is equipped with a reader arm which is capable of reading and writing data on the disk. Inside a Hard Disk Drive – Foto by The magnetic platters in HDDs are divided into several discs or platters, which are stacked on top of one another. Each platter has a surface coated with a magnetic layer, which functions to record and store data in the form of a binary representation, namely zero (0) and one (1). Main Functions HDD has several main functions in computers and data storage devices, including: • Data Storage The main function of HDD is to permanently store data on a storage device. HDD has a larger storage capacity compared to other storage devices, such as SSD (Solid State Drive), flas...

PATA stands for Parallel Advanced Technology Attachment. A motherboard has many components in it. Each component has its own functionality. There are cables used for different purposes in a motherboard and PATA is one of them. Parallel Advanced Technology Attachment(PATA) also called Advanced Technology(AT) Attachment is a bus interface used for connecting secondary storage devices like hard disks, optical drives to the computer system. The functionality of PATA is to transfer the data. History PATA was introduced by a company named Western Digital and Compaq in the year 1986. When introduced, it was named as Advanced Technology Attachment or ATA in short. The cable was named ATA as it’s main function involved transferring of data. Later on, when SATA was introduced in 2003, the bus interface was renamed as PATA. Serial Advanced Technology Attachment(SATA) was introduced as PATA was subsequently losing its place in the market. The reason is the speed of data transfer was slower and the price was higher. With SATA being introduced, the demand for Parallel ATA slowly declined. Types of PATA Cables PATA cables are of two kinds. They look quite similar but the functionalities are different. They are also called as IDE. • PATA 40 conductor cable: It was first introduced to connect devices which has a transfer speed of 33 Megabytes per second(Mbps). A user can connect a maximum of two devices to the cable in the motherboard. It was later replaced by PATA 80 conductor cable. • PA...

A computer hard drive (or a hard disk or HDD) is one kind of technology that stores the operating system, applications, and data files such a documents, pictures and music that your computer uses. The rest of the components in your computer work together to show you the applications and files stored on your hard drive. A hard disk drive (HDD) is composed of a platter that contains compartments to hold data. This data is your operating system, applications, and any files you have created. There is also an accuator arm that moves across the platter to read or write the information requested. To make this process faster, the platter spins as the accuator arm moves across it. The compartments that hold the data can be spread out all over the hard disk. That is, data is not written sequentially. There is an indexing system to allow the accuator arm to find all of the pertinent data. The platter and the accuator arm are delicate, so they are covered by a steel case. This prevents damage to the disk under normal circumstances. HDDs are proven technology that can hold a large amount of data (this varies by the size of the drive) and are relatively cheap. Under normal use, they are reasonably durable and function well. There are drawbacks, however. Hard disk drives can be slow, especially to open large applications or files. Because they do not write data sequentially, the data can become fragmented, with empty space within each compartment. This empty space is too small to use for...

By • • Site Editor • What is a terabyte (TB)? A terabyte (TB) is a unit of digital data that is equal to about 1 trillion 40 bytes, or 1,099,511,627,776 bytes. The terabyte is typically used as a measure for The prefix tera is derived from the Greek word for monster. It would take 728,177 floppy disks or 1,498 CDs to hold 1 TB of information. However, computers can now be configured with hard disk drives ( As with other data measurements, computer, storage and • The base-10 standard uses the decimal system and specifies that 1 TB is equal to 10 12 bytes, or 1 trillion bytes. • The base-2 standard uses the binary system and specifies that 1 TB is equal to 2 40 bytes, or 1,099,511,627,776 bytes. When storage capacities were smaller, the discrepancies between the two standards had little impact, but now that much more data is being stored, these differences have greater significance. For example, when the decimal standard is used, 1 TB is equal to 1,000 gigabytes ( The difference of 24 GB can represent a substantial amount of data. For this reason, the term Base 2 (binary) vs. base 10 (decimal) measurements Terabyte history In 1983, IBM released the Sixteen years later, in 2007, Hitachi began selling the first 1 TB HDD to consumers. The HDD marked a milestone for data storage, and it also emphasized how rapidly storage capacity was growing. With the drive's release, Hitachi noted that it took 35 years for the storage industry to reach 1 GB and 14 years to deliver 500 GB. Afte...
