Is this real... How To?

Thanks for all the replies!!




Im gonna try some of the recamendod progrmas now.

 

I just read something recently, according to Gutmann himself, none of these methods, including his, is as safe as you thought.

 

How about a BMW?

Mmm, if I've read those articles correctly, there is little evidence for Guttman's claim that physically overwritten sectors can be recovered using MFSTM (Magnetic Force Scanning Tunneling Microscopy).

It is mentioned that is useless to apply non-MFM writing patterns on MFM encoded disks (floppy or HDD).
So that's why it is useless to overwrite a HDD with patterns of 'random' data which are based on old-school encoding methods.
Simply put; if you have a modern HDD with modern encoding, you only need to use an overwritting method regarding that specific encoding method.

The second article also claims that there is little evidence that besides some intelligence agencies (who have access to a Magnetic Force Scanning Tunneling Microscope) others can read data of a HDD that has been erased using modern day erasing methods.
The author of the second linked article mentions a published article by Charles H. Sobey, he suggests that " it would take more than a year to scan a single platter with recent MFM technology, and tens of terabytes of image data would have to be processed".

For a NASA HDD that has to be recovered, this might be a viable option.
For the average Joe like me, I'd say DBAN or Active@Killdisk is still more than enough to wipe an obsolete HDD.
Cheers.

 

what he said^

 

Very true. I think I misunderstood the articles.

 

Rep for Baserk

And for all of you saying "CSI: Miami" is great:

It's only great as a drama. If you like overacting. NONE of the CSI's have a serious grounding in proper science. Here's some interesting reading on the CSI effect and the ability of those shows to warp people's perceptions about what is real and what isn't. Most of the crap they show ("I'll hack together a VB app to trace an IP!" "Let's zoom in 10x and read the license plate across the street on this $100 black and white security camera" "Let's get 100% positive and conclusive results from all chemical tests!") is not based on anything other than the imagination of a Hollywood writer.
