Should I be worried about my SMART values of my drive?

Question

From what I gather, this is really really bad. I should probably replace my drive. But could I get verification that I am correct before doing so?

Answer 1

Yes, if any of the bad sector counters (including pending, reallocated) in the SMART data of a hard disk drive are nonzero, it means the drive is dying, the error rate will only snowball (grow at an ever-accelerating rate) from here, and the drive should be replaced ASAP.
