It has been a well known fact for years that data cannot be erased from hard drives. The obvious fact that millions of bank accounts/CC details have not been stolen from home computers would lead one to believe that there are not gazillions of people trying to do this.
Anyone who believes that super trained criminals are lurking at computer fairs or scouring Loot/TradeIt for 2nd hand computers to steal passwords from and have the equipment, knowledge and capability to decipher disks is totally away with the fairies and should be banned from reading any 'security' articles that they are unable to understand - While not a personal dig, and in no way wishing to be a direct attack, diss, have a go at, slander, upset, or in any way suggest that this person does not know what they are talking about, or even suggest they they are incorrect in any way in what he (Or she) says/thinks. (so they will not be named.
This is the dullest, uber-paranoid article that I have ever laughed at. Reds under the bed next and it comes as no suprise that it is 'they are all out to get us' American in origin.
ps the article is about 'stealing' passwords from physical items, hacking is about electronic stealing over a distance, so the name of the thread is a little incorrect ;-))
