• Degaussing-this is the process of eliminating or decreasing a remnant magnetic field such as the hard disk drive of your computer and wipes the media from it so it can be safely and securely disposed..
• Physical disk destruction-this is where you render the platters severely fragmented and the disk inoperable.
If you are concerned about any sensitive data being left on your hard drive when you recycle it then the physical destruction of the disk is the best method of protection. It is also referred to as hard drive shredding and is a secure way of disposal. By doing this you are getting rid of confidential data by overwriting the deleted files. You want to make sure that the data that you have erased from your hard disk cannot be recovered anymore by anyone once you have deleted it.
When deciding to do hard drive shredding you need to be careful about the kind of software you use to complete this task. If you chose file shredding it will let you choose the file that you want removed and will only remove that particular file but nothing has been permanently removed and the file can be recovered. With hard drive shredding, or data destruction, it is the only way to remove completely any remnant data on a disk by using methods to get the remaining data and making it unrecoverable by anyone else.
Some of the benefits of using hard drive shredding includes:
• It will remove any chance of your data ever being recovered
• It will only touch your deleted files.
• It gives you increased data security because a shredded disk or hard drive cannot be patched up and made functional again.
• Helps to reduce the risk of having improperly discarded hard drives.
Hard drive shredding is the best method to use, especially for companies who are not going to re-sell or donate their old computers and just want to recycle them and keep customers sensitive information out of the wrong hands.
