"Supposedly the magnetism slightly modifies the formation of the metal itself, and degaussing it does not completely undo what happens to the metallic structure."

That's a bit of a stretch.

When you hit a hard drive with a bulk magnetic tape eraser, it's very akin to a bull in a china shop.

There is nothing subtle or gentle about the magnetism coming from a huge electromagnet running under AC mains power where such a scenario could be probable.

@Watcher3223 Supposedly the magnetism slightly modifies the formation of the metal itself, and degaussing it does not completely undo what happens to the metallic structure. Apparently with the right equipment, it can be recovered from the very metal itself. From what I hear, anyway.

'i forget the technical jargon but data always leaves a signature, even if you magnetically erase it, it can still be reconstructed'

With erasure of this magnitude, reconstruction is impossible short of buying a new drive and restoring from a backup.

If you degauss the platters to the point where you obliterate low level formatting, you'll also completely obliterate the high level formatting and ALL data contained within it with absolutely, positively no chance of recovery.

Rewriting the drive several hundred passes and then scrambling it with a neodymium magnet should do the trick.

well you have to consider the source, and what 'secure' means...

i know if I were the NSA, i wouldn't be telling you how to 'absolutely secure your drive' if i didn't have a way to recover it!

imagine if terrorists could secure their drives with a magnet... no. this is security that works for most people who might look at it, it isn't absolute.

Indeed and old comment....man I have since graduated from university and gotten so much older and wiser... anyway, the term I think is data remanence. but according to wiki referring to CMRR, most ATA drives > 15GB can be securely erased after just one overwrite....even NSA agrees...

[gwilendiel]

just stumbled on this video... though this is a two year old comment, I have to agree with you.

i forget the technical jargon but data always leaves a signature, even if you magnetically erase it, it can still be reconstructed, kind of like a 'residue' left on the drive for a lack of a better term.

but if you overwrite it many many times with random data on each pass (500 times in your example) this masks the signature. then you fill it with legitimate but not sensitive data to mask it further

magnest desroying a hdd haha if its flash wave then ti can destroy but normaly not always
