It makes this noise:
- every time a game starts when loaded from my USB drive.
- with different games.
It's much louder than my recording.
Using the same USB drive on my sisters console (4GB as well), I do not hear this alarming noise.
This noise does NOT occur when a game is NOT installed to a memory source. BUT I will NOT be playing via the DISC. I will always install the game to a memory source.
If I cannot get any help here, I will be returning it.
