A computer does what it does because of hard drives. A hard drive, which are found in all personal computers are the ones responsible for storing large permanent data like operating systems, programs and user files.

Hard drives first came out during 1956 through IBM, Its serve as a mass storage device for computers. Data saved inside the hard drive can be erased or overwritten. It is classified as non volatile storage device meaning it can store and retain information with out the requirement of a constant power source.

If you're wondering if your personal computers can function without its hard drive, the answer is yes. Computers can function without a hard drive, but it would be virtually useless for you, the hard drive's large storage capacity allows you to save operating systems and programs necessary to run the personal computer properly and to its maximum.

A hard drive stores memory through the use of platters, these are described as small round disk-like objects made of either an aluminum/alloy or a glass/ceramic composite. These platters are very sensitive to foreign objects and virus programs. Failure to prevent such problems in the future may result to destructive consequences in ones computer unit, so basic knowledge about the maintenance of the hard drive is a must.

As platters are protected and incase in steel casings, these protection is not enough for it to overcome the infestation of mal ware obtain from unprotected surfing in the internet. To avoid such events, a computer's hard drive is protected with a free anti virus program upon purchase. But these programs do not last long. To have a long term and complete protection from viruses the market today sells top of the line anti virus programs, anti malware and excellent firewalls.

Updates and a backup storage device is also a nice addition to your pc's hard drive. Every operating system has a regular update done to the system. Let this updates run automatically to keep the hard drive's operating system, mail and browser up to date.

Back up data storage should also be given attention. With all the updates and anti malware programs installed, sometimes the system still crashes. To recover the data lost and external storage device must be available. This may be in the form of discs, USB, or external hard drives.

As data loads up in the hard drive, the system will eventually slow down. To overcome this dilemma a registry cleaner must be installed. This clears unwanted data around your data storage so that it may result to a better performance from the operating system.

Hard drives are great inventions that are very vital to the personal computer; it allows you to store up large amounts of data and with the evolution of technology, and no one knows what the hard drive store for us in the near future.
