Formatting a hard drive does not completely erase data either. Simply deleting files by Shift + Delete or emptying the Recycle Bin does not permanently clear data, as deleted files can easily be recovered by recovery software. However, the fact is that wiping out a hard drive is not as easy as deleting data or formatting hard disk. You may have already formatted the hard drive or deleted files on it in order to erase sensitive personal data and avoid becoming the victim of identity theft. It's common to most users to sell or give away computer or hard drive when they want to dispose of old device or upgrade to new ones.
