Hey, I heard the other day that a HD should never be ran at odd angles (anything other than 0,90,180,270,360). Meaning it should always be flat, or standing perfect straight.

Is this true?

Also, I have a HD standing cuz I had no room left in my comp, and I notice after awhile it was struggling now and then, it would need to click in (clunk) alot when reading files off of it....So I found a place for it, unfortunatly it is upside-down (chipset facing up), but it is flat.
