Noise and Vibrations

hey can you shed any light on this…
i have the plextor px-716a and the other night i decide to install far cry. its during this installation i noticed that the drive is a bit noisy compared to my px-708a. is it normal for this drive for it to be noisy? it also vibrates as it slows down…

Hmm… more and more people complains about vibrations… anyway, prankz, it’s being discussed here http://club.cdfreaks.com/showthread.php?t=122137
