S.M.A.R.T. reports bad sectors, but badblocks no errors?

What should I make of a drive for which S.M.A.R.T. reports 8 bad sectors

I think it depends on the drive is.
I suspect that any drive that has S.M.A.R.T. also has spare sectors that
aren't visible to the OS.
As such, it's entirely possible that the 8 sectors are indeed bad and
have been swapped out with spares that are good.
Running a bad block check from the OS (outside of the drive & integrated
controller) on such a will likely not see any problem(s).
