beware of it!

Hard disk drive also known as hard drive or hard disk is a non-volatile storage device, which has the facility to stock up digitally encoded data on rapidly rotating platters and magnetic surfaces. Its design consists of a spindle which can hold one or more flat circular disks known as platters, onto which the data is recorded. Today, the boost in disk space and access speeds of hard disk drive have further facilitated the marketable viability of clients products that need great storage capacities, like digital audio players and video recorders.

Yet, the main problem that we are coming across is erasing data or files from hard disk permanently. Many people consider that the effective way to erase hard drive data is by formatting the hard drive. So, the question now is how to reformat hard drive permanently! Though formatting the hard drive is somewhat secure than just erasing the files, but you should also note that formatting a disk does erase only the address tables. It makes it much more difficult to recover the files. However a computer specialist would be able to recover most or all the data that was on the disk before the reformat. Thus beware of it!
