It is more than acceptable to dispose of your hard drive disk at home. Most people just throw their computers in the trash when they purchase a new one, or they scrap certain parts and leave the rest in the dumpster. When it comes down to it, just throwing away your HD is not enough in today's world. Dumpster divers, con artists and hackers can use that hard drive and mine data on it that could include bank account, credit card and other information to steal your identity, money and life.

You can even destroy the drive, but it is dangerous and cause pollution; save money and a bit of our eviroment using Wiperaser: come and check how.
