Most games released in the last 4-6 months are on a new disc format (for more advanced copyright protection), and even if they're installed, the 360 reads them pretty vigorously for about two minutes after starting them. After that, the drive shuts off and the game plays from the HDD normally.
I would like this as well. I just got a 4GB Slim 360. And the drive is just too noisy... is this normal. it sounds like HRRRRRMMMMMM like for 5 minutes straight and then it shutdowns
Wait, just re-read that you have a 4GB, so you wouldn't be installing games... I guess it's still normal that the drive sounds like it's going crazy for those first couple minutes, though. The rest of the time it shouldn't be accessing as much.
