Hi. I found some cool software called Insomnia which lets you disable the sleep mode for when you close a MacBook's screen and I was wondering if I would be able to have the screen closed and the MacBook running a program being tilted on its side. Can i do that without wrecking the hard drive? The room where I would do it is ACed and the MacBook would be littery right on the AC vent. Im not worrying about over heating just if the hard drive will be ok because my one firewire drive if you tip it on the side it makes a grinding noise. But if its flat its silent. Any ideas? O yeah i attached the Insomnia app if anyone wants to try it.
