I just bought a 120 GB Western Digital Cavier SATA drive, and I noticed today that it's making clicking noises. The drive is barely 2 weeks old, and it seems to completely stop responding occasionally and then it'll start up again after a few seconds. I noticed it first when I was playing KOTOR today, and later on when I was watching TV my whole system just decided to restart itself. Should I send the drive back for a replacement, or is it just overworked from me playing 12 straight hours of KOTOR?
