I learned what Windows "Quick Format" actually does (and it’s terrifying)

We've all done it, plugged in a USB drive or went to wipe an old HDD and found the "Quick Format" box in Windows because we didn't want to spend hours waiting for a drive to reformat. There's a reason, though, why a full format takes so long. Quick format doesn't do anything except hide the map to the files on your drive. After a Quick Format, the data is all there, accessible by anyone with technical know-how. If that matters to you, and it should, then take a look at why you might not want to use Quick Format, when you might be ok with it, and the options available to you from there.
