I have a 2TB internal hard drive that might be failing. It spends several minutes at 100% usage when I first turn it on since I installed Windows 10, and yesterday it reported a corrupted Recycle Bin.
In short, the Uncorrectable Sector Count count is 100, and this is a "caution"-level problem on the drive. No other labels are "caution".
I'm not sure what to make of the Current, Worst, and Threshold values. I know that some of their actual values vary by manufacturer, and I've also read that if a current value is below a threshold, that statistic has failed.
The value of the Uncorrectable Sector Count is 100, which is also its worst-recorded value, and the stat has a threshold of zero. Additionally, various other stats read that 100 is both their current and worst while not being marked "caution".
Why is Uncorrectable Sector Count being displayed as caution if various other stats with the same value and threshold aren't? How can a lower-than-threshold value occur with a zero threshold? Is this a sign of imminent drive failure or is the tool merely miscalibrated?
EDIT: Seagate's SeaTools utility has reported that SMART is OK, but it didn't say anything else.
