Hello, I currently own a Seagate ST320005 42as SCSI disk device (At least thats what device manager says) Anyways, randomly through the day but more often when gaming specifically playing Star Wars the Old Republic, it will emit a seemingly random, single click. Rather loud too, what I don't get is neither Disk Check, nor Sea Tools shows any bad sectors, I don't have the money to replace the drive, and am wondering should I be worried as hell?
