I have received a notification from Scanner that S.M.A.R.T. check is predicting imminent failure for one of my disks. However, when I clicked into the S.M.A.R.T. health details, all attributes had green checkmarks--none were flagged as an issue. I checked CrystalDiskInfo, which did not report any issues either. I then removed the disk in question and then reinserted it. At this point the warning cleared and Scanner reported the disk as "healthy." A few days later I got the same warning of imminent disk failure for the same disk. Just as before, no issues were flagged in the S.M.A.R.T. health details, and CrystalDiskInfo still reported the the disk as "Good." I powered off and on the disk, the warning cleared again, and Scanner has been reporting it as healthy ever since. Is this buggy behavior, or should I be concerned that my disk is failing?
