For data removal, just call me, I manage to wreak havoc on hard drives without any special know how. I've got several that are beyond the point where data can be retrieved, or so I'm told, since they won't spin. Or I can pay somebody giga-bucks to try and retrieve the info. And I would really like to get the stuff off of them; projects I did, etc. Yes, I use a separate hard drive now to back up everything...
My wife handles data distruction for me.... I kept asking her not to reach across the desk and over my external harddrive.... She did it anyway....and eventually exceded even my darkest expectations...
