I'm using a 5400rpm SATAIII drive on my SATAII port, if this matters. it passed diagnostics such as WD data lifeguard, seatools, hdat2, and smart info seems normal.
when i cold boot my machine, it has made the click-click sound continuounsly on 3 occasions. once it gets into windows, i can't see the drive. after i cold boot it again, it's fine.
it's done isnt' it ....?
