How Hard Drives Work and Different Types

Every computer in the world, be it a supercomputer, desktop computer or server, contains a hard disk drive. Some mainframe supercomputers even have multiple hard disk drives to meet higher computing requirements.

Hard disk is one of the major, and normally the largest, data storage devices found in computers. It stores a number of software utilities, operating system components, media files, important documents, certificates and anything else that comes in digital format. HDDs are the essential parts of our desktop computers, and thus it is worth to have good knowledge about them.

harddrivesWhat are these hard disks or hard drives? Why are they so important for computers? The following post sums up good information about HDDs, their functions and importance in the computing world.

Hard Disks Explained – How they actually work?

Hard Disk Drive (HDD) stores digital information in the relatively permanent form. It is a widely used data storage device in which you can store and retrieve digital data using the fast rotating discs (platters) that are coated with magnetic material. In simple words, it gives your computer an ability to store your data and hoard the things for a long time.

They were firstly introduced in 1950s, as the large disks of about 20 inches diameter with capacity to hold just few MBs. Earlier, they were called as “Winchesters” or “fixed disks”, but later they became the “Hard Disks”, in order to differentiate them from the floppy discs.

At a simplest level, hard drive can be considered as a cassette tape, because both these data storages use the same kind of magnetic recording technique. However, instead of the flexible film of floppies and tapes, the hard disk contains a solid hard platter which embraces magnetic medium.

How Information Is Stores and Retrieved From Hard Disk?

Data stored in the HDD is interpreted by hard disk controller. It tells hard disk how to move and what to do with data bytes stored in the drive. If the OS needs to write or read data, the controller first examines the FAT (File Allocation Table) to find out available areas and location of saved data.

After finding the exact locations, it signals actuator to align R/W (read/write) head and move R/W arm. Since files are spread all over the platter, R/W head should move to diverse locations in order to access the information.

The data storage is done magnetically. If computer wants to read the data from hard disk, it reads the magnetic properties of that location on platter.

Internal and External Hard Disks

While most of the hard disks are internal drives, you can also use the external HDDs in order to take data backup or expand the storage capacity of your computer. These external drives are usually fitted in the HDD case (enclosure).

In addition to providing extra protection to the hard drive, the HDD case allows you connect your PC over eSATA or USB. Some newest external HDDs are quite compact and flexible to make your data storage much easier. You can simply connect your external hard drive to any computer or laptop to transfer data to/from the hard disk.


Why to Defrag

defrag20x2Just like your house needs occasional spring cleaning, your PC needs it too. Defrag is a maintenance process needed for the optimum performance of your hard drive. When Windows modifies, deletes and write files it creates empty spaces or blocks on the hard drive. The empty space is available in pieces and bits. Overtime, files that Windows write on the hard drive can be fragmented between the spaces. Again, Windows can break larger files into pieces if it cannot find a space large enough to contain it on your hard drive. Installing and uninstalling programs are some of the activities that fragment the hard drive. This leads to fragmentation, which can negatively affect the performance of the hard drive.

What will defragmentation do to for your computer?

When the free space in your hard drive is fragmented, there is a high chance that your other files can also be fragmented hence it is important to tackle fragmentation. Defragging your system will put the empty spaces or blocks together in sequential order. Fragmentation may not slow down your computer initially; but as more blocks on your hard drive are broken into pieces your computer may become slow. Defragmentation will enhance Windows’ performance when writing files. Again, when you defrag you prevent fragmentation of new files.

When should you defrag?

Many people are of the idea that defragging will make you PC run faster. While we expect optimum performance from our machines all the type, manual defragging may not always be the requirement. There are three types of cleaning your computer and optimizing its performance, which are, disk cleanup, error checking and defragging. These cleaning methods should be done systematically. To make the defragging process easy and quick, you should start by cleaning the disk, followed by error checking. You don’t need to defrag constantly though. Depending on how many times you add or remove files from your system, you can defrag in intervals of 3 to six months.

Should you use third party apps?

Windows computers come with an automatic defragging app, particularly Windows 7 and Vista. However, you may need to check if the defrag is running as scheduled. For Windows XP you may have to set up the defrag schedule. A computer with solid-state drive (SSD) does not need defragmentation at all. This is because SSD does not store data on spinning platter and therefore do not need additional time to read or write files.

Mac users also don’t need to defrag because Mac has a built-in defragger. The defragmentation will automatically be carried out by Mac’s OS X. However, if you deal with large files excessively you may have to check if your machine does not need defragging.

Many tests have proven that commercial defragging software can improve your computer’s booting speed more efficiently than default defraggers. Third party apps have tools to help you defrag the registry and files.
