Best Methods Of Data Destruction On Computer Hard Disk
« on: Thu Feb 24, 2011 - 10:31:53 »
Are there any other options?

I believe that physical destruction is the quickest and simplest approach. By removing the top plate of a hard disk drive, you limit the chances of recovering the data due to dust and other contaminants affecting the drives platters (where your data is stored). Physically scoring lines or drilling holes into the platter will hopefully destroy the data beyond any reasonable doubt.

The concept of shredding paper to deter criminals using printed material such as bank statements or bills for identity theft and forgery has now been taken to the next level. Available now is an industrial tape and hard disk shredder. If you search within Google "GSA Industrial Tape and Hard Drive Destroyer 380/500" you will witness the future when it comes to data destruction.

This powerful machine, whilst not commercially viable for the home user, would suit any large company where data destruction was crucial to their intellectual electronic property. Using this machine would render data retrieval practically impossible. I cannot imagine a point in the future where we would be able to reconstruct the data from shredded material.

Obviously this method would mean a user couldn't resell their hard drive. However as the cost of hard disk drives decrease year in year out, is the cost of another hard drive really an issue?

To summarise, the benefit using the software or hardware approach would be: reusability and the chance to recoup some money. The disadvantages would include the 'risk' involved by relying on software or hardware to completely destroy your data. Another disadvantage would be the time consumption and costs involved, including electricity and human resources.

The main advantage of using a hard disk shredder is that complete 100% destruction can be witnessed. The destruction can take as little as 30 seconds. The main disadvantage is that such machines are currently not widely available. As the disks cannot be reused it is not an environmentally friendly approach. The last disadvantage is that the costs involved outweigh those of a software approach.

I've always found a few .20 gauge slugs to work fine for keepin my bits safe from prying eyes.  the first slug will rip the platters in the drive to shreds, and the other slugs are for anyone who comes to look at the pieces...

To what level would you like to keep your data secret?

You have the option of degaussing the drives, but this requires special equipment.

Drilling holes will destroy the data that used to be where the holes are; it will not do anything to data on other parts of the platters. That data can still be recovered.

Physical destruction, to an appropriate degree is the most secure method of keeping your data secret.

However, the level of destruction should match the likely threat, and likely damage to you if someone recovered it.

I still think shooting them is better. 

By "better" I mean "more fun."

Physcial destruction is only way.  It can be hard though.  I tried melting the platters down with an acetylene torch once and it did not do much.

Unless you're trying to hide the locations of top secret nuclear bunkers from the Chinese army, you can just reformat the drives and write random bits to all the sectors a few times.  Sure, the NSA can still get to your data if they needed to, but Johnny Neighbor likely won't have access to the right software or hardware to read beyond one wipe/write session, much less two or three.

Anything that's that important should have been encrypted in the first place.  A random wipe/write on top of an encrypted file will stop even the NSA.

There is a free program called "Bit Eraser".  A lot easier and less destructive than smashing it to "bits".
