One good reason to build your own system

Effective method, but not good enough. If you have enough money and the right tools you can still get data off of those drives. The only way to be sure the data can not be recovered is to melt the thing down.Duper wrote:Our tech guys at work hang the platters up around thier cubes.
Don't keep sensitive data on your hard drive UNENCRYPTED. TrueCrypt is high quality and free. It allows you to create encrypted drives on your computer that work just like normal drives. (you can drag and drop files into them, etc). BUT, all of the data is actually encrypted with modern high strength crypto algorithms (you can pick from several). No one can mount the drive without the passphrase. Probably not even the NSA. Keep all of your personal data in a truecrypt drive and you only have to worry about swap partition leftovers.Krom wrote:the lesson here is don't keep sensitive data on your hard drive period.
Absolutely true, but if you don't feel like taking a blowtorch to your drive, Eraser will make it unlikely that anyone other than a government agency would ever recover your data.Richard Cranium wrote:The only way to be sure the data can not be recovered is to melt the thing down.
Only works if the HDD is still in a working condition..Kilarin wrote:Absolutely true, but if you don't feel like taking a blowtorch to your drive, Eraser will make it unlikely that anyone other than a government agency would ever recover your data.Richard Cranium wrote:The only way to be sure the data can not be recovered is to melt the thing down.
Eraser comes with "Darik's Boot and Nuke" utility now.
'Darik's Boot and Nuke ("DBAN") is a self-contained boot floppy that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.'

VERY valid point.Grendel wrote:Only works if the HDD is still in a working condition..
In theory, yes. But the question is, how strong should the magnet be in order to effectively destroy the data? Fridge magnet? Subwoofer magnet? Car pickup crane elektromagnet?Diedel wrote:If your HD breaks, put it close to a good strong magnet and move it around there for a while before returning it. That should take care of your data.
Just like a little kid, they shut up when they know they messed up...A Best Buy spokeswoman didn't dispute the details of Gerbus' story, but wouldn't answer questions about the incident.
Correct, you can stick the magnet off a 18" speaker to your hard drive, and then plug the drive in and boot off it with no problems. The shielding on the drives may not be hugely thick, but it is rather effective. Just any magnet you have sitting around on your fridge won't cut it no matter how long it is sitting on the drive, unless the magnet is strong enough to lift your fridge off the ground.Tricord wrote:In theory, yes.

You still can't know for sure.
And in that case, good luck getting it off your fridge.Krom wrote:Correct, you can stick the magnet off a 18" speaker to your hard drive, and then plug the drive in and boot off it with no problems.

That's because it's not the length of time you leave the magnet there that does the damage it's the change in magnetic flux brought about by bringing the external magnet into proximity of the drive. Once that stabilises no further damage will be done. Until of course you upset things again by moving the magnet out of the way. In other words, what you want to magnetically scramble a HDD isn't a hugely powerful fixed magnet but rather a moderately powerful electromagnet that you can pulse on and off.Krom wrote:Correct, you can stick the magnet off a 18" speaker to your hard drive, and then plug the drive in and boot off it with no problems.
