preacherman> well, now it can't really, but back in the day....

One of the things that used to be fun to do, but really expensive, was a pretty simple asm program. You could actually tell a harddrive to read sectors that didn't exist. So lets say your hard drive has 200 sectors. Now, you tell it to read sector 220. What happens? The arm keeps moving right past the platters and breaks. Well, now the drives are too smart for that. shows how much even simple technology can change.
