See, the biggest problem was actually caused by S.M.A.R.T that day i posted, which i had enabled the day before and forgot about. The whole computer was acting up when accessing disks and i saw the error more frequent till it actually caused a panic, hard rebooted, and vanished from the bios listing. When i pulled it out it seemed somewhat overheated. the thing is though, i never had S.M.A.R.T enabled before and still saw the error sometimes; and pretty sure it depended on the install - either i see it often, or not at all on this particular disk. anyway, thanks all for the input
