Will putting a magnet near a hard drive damage the hard drive rendering it useless (and a professional can see that its been damaged by a magnet) or will it just make the data inside corrupt and inaccessable?

I think it will actually render it un-useable

you will probably need a beefy magnet to really corrupt the data. little ones won't do anything. i would imagine that the drive would still work fine (albeit with screwed up data on it), it would just need a formatting. someone correct me if im wrong, ive never personally done any of this.

it will only corrupt your data a bit, not render it useless.

what about hooking it up directly to a 12v battery? (just so i know if i ever need to destroy my data quickly)

hooking it up to a battery would (not sure on the voltage/amperage that it normally uses), if it's over the HD's limits, only fry the controlling circuits and cache (AFAIK, anyway) the platters where the data is stored would remain intact and could be recovered by removing the platters and placing them in another compatible hard drive. I don't think that little magnets would really do anything but I do know that there are products on the market that can nearly instantly wipe a HD and/or magnetic tapes. As for making them permanently unusable via magnets.... not sure.

EDIT: the dishwasher would probably fry the electronics, not sure if the platters would be destroyed or not though... again not sure about the platters in the micro either... I DO know that a microwave will definetly fry a CD.... if you really need to make an HD unusable you could just do the easy thing and smash it, hopefully shattering the platters.

High power magnets will FOOK a drive for good. It will fry the little proccessor thats on it. Much like static to a ram chip. But as stated before it has to be a Beefy magnet. They used to make these big electromagnets used for clearing vhs tapes. they worked wonders!

Friend had to do this to an HDD once...dont ask me why you probly better of not knowing :ninja:

taking a sledgehammer to it or dipping it in acid would be a lot faster :devil:

depends on the magnet...

putting anything with a fan near a hard drive, computer, monitor can NOT be good...

putting a fan beside a monitor (like we do at work) messes up the monitor.

depending on the strength of the magnet.. you will do some damage.

To clear the data, you really need a VEFY powerful magnet. I have read around 10,000 gauss or higher.
