Maybe a silly question.... At my office we have two ways to "destroy" a harddrive: 1. Using the tool called "Secure Erase" We use that if the harddrive is to be re-used. 2. Using a tool called "Hammer the drive flat" We use that if - take a guess Now here comes the question: How to properly erase a SSD drive, that is to be re-used, and to be sure that no old data can be read??
