ERASE A HARD DISK DRIVE PERMANENTLY By Vijay.
A 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. It has the ability to store data more than floppy disk drives and can also access and transmit data at faster pace. 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.
However, the main problem that we are coming across is erasing data or files from hard disk permanently. Most of us think that erasing files and emptying the Recycle Bin will help in permanently get rid of those files. In fact, in most of the cases Recycle Bin tells that emptying the Recycle Bin will permanently remove items. But this statement is totally incorrect.
You have to understand even after emptying the Recycle Bin, the files can be easily recovered by data recovery programs. Making the best use of delete key on actually removes the shortcuts to the files and makes them undetectable to users. Deleted files still reside on the hard drive and a rapid Google search will automatically show options for system recovery software will further allow to restore that data.
