leaving computers on...

I read somewhere that it takes more energy starting a computer up when it's been off for less than six hours, than if you had just left it on the whole time.

Confirm/deny?

plz post proof

This is simply not true, almost all of the physical wear and tear that occurs to hard drives is done during the power on/off stages. A hard drive that is turned on and off once every day will have a drastically reduced mean-time before failure than one that is left spinning.

Of course, if you aren't going to be using your computer for an extended period of time (6+ days) then it is probably more beneficial to turn it off.
