goto the store..buy some clorox come home put hd in a bucket..I'd put a towel under the bucket cause when you for the clorox into the bucket..it may splash and get on your floor..then you'll bleach your floor as well as hd..fill half way and add 3 cups of water..slowly insert Harddrive into bucket..(if you drop it..it may damage hd or splash the clorox.).there you go..leave in for about thirty minutes for a full harddrive bleach! take out and blow off with canned air..put back into your computer/laptop..this will work with anysize hd under 1 Tb anything over that..id use more water!

Enjoy
