Ran a SMART check on one of the drives on my server and it showed a few offline uncorrectable errors.

I'm wondering if there's any relation to this and the overall health of the drive, since it's still coming up as "passed"

I'm just curious, as I'll be swapping out the drive since I've also noticed an increase in the reallocated sectors count over the last few months and that's the only drive that seems to be having problems; the other two are fine.
