When disposing of a damaged hard drive, even though you've deleted all of your files to the recycle bin, you are still at risk for data theft. Many users do not realize that deleted files can be recovered. One solution is to install software that will truly erase all files, if the hard drive is still functional. According to PC World, DBAN (Darik's Boot and Nuke) and Secure Erase are downloadable software applications that can be used to erase hard drives simply and effectively. If you wish to dispose of a damaged hard drive permanently, total destruction is the most effective erasing method.
