The Most Secure Way To Delete your Data On Your HDD

April 16, 2009

My earlier post pointed to a method to recover some of your data from your dead hard disk drive. Now, I have found a way to do just the opposite, annhilate every bit of information that ever existed on your hard disk (and along with it the HDD itself)

An article on the MIT website (http://web.mit.edu/newsoffice/2003/diskdrives.html) pointed out how vulnerable your deleted data is for recovery.

Consider this ” Scavenging through the data inadvertently left on 158 used disk drives, the students at MIT’s Laboratory for Computer Science found more than 5,000 credit card numbers, detailed personal and corporate financial records, numerous medical records, gigabytes of personal email and pornography. ”

These HDs were bought from eBay for less than $1000.

This and one of the most sophisticated techniques as explained at http://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.html can make you almost paranoid about the security of your data.

So, here is a grand method explained here.

Its simple, just melt the hardisk down! This will destroy the shape and the HD itself, also it will destroy all its magnetic properties.

Good luck to anyone who wants to recover credit card numbers from this!

    Most computer users now tend to d/l various file deletion programs from the net thinking that they will destroy all data.The only true way to get rid of all data is completely destroy your hard drive.However not everybody will go to the extremes of using a blow torch.

      But isn’t that a good idea?

    Yes and no. For instance say you want to sell your computer will you sell minus the drive!! Most people will not buy a pc without any drives.

      What if you have your credit card numbers stored, or maybe you are a secret agent, carrying out political assassinations, who stores the list of his victims. Won’t you be compromising your security by giving out such sensitive information?
