I have had my Rev A Dual 1.8 G5 forever now. I switched the original super drive for the new Dual Layer one about 6 months ago. I havent tried to put the machine to sleep for a very long time because of torrents and serving etc, so I cant recall if I ever got it to sleep with the new drive, and I am 80% sure I did. Anyway, when I try to get it to sleep, either thru the apple menu or thru energy savers timer, everything goes well, the monitor goes black and the drive goes click click click click, like its stuck or something. If i remember it always did make a tiny click before going to sleep, but now its like stuttering and wont sleep (i.e. the fans dont stop etc) I have to hit a key or whatnot to make it stop and everything goes back to normal. I still torrent alot so I dont mind it, but whats going on here?
