Wipe a hard drive

What is the purpose and the method to wipe the hard drive?

A Hard Drive is a storage device which stores different types of data including pictures, movies or text. Large hard drives of about 250 GB are used to store different files on your computer when system crashes due to virus infection. Smaller hard drives are used to store and transfer files between different computers. The external hard drive allows you to quickly back up all the data in your computer. Hard drives are disk drives that are usually fixed into your computer and their size ranges from gigabytes to terabytes. The size of hard drive in desktop varies from that of the laptop but their purpose remains the same.
