I have the 7200.7 I think and it has been recently making whirring noises randomly during games or when idle. I hear this is part of the scanning process. I have had the drive for about 2 months and it just started about a few weeks ago. It seems to be happening less but still I am worried. I have run the SeaTools drive chec and it turned out OK but was wondering if you guys could tell me if it seems fine. Thanks.
