Calibration Retry Count error on HDD

[markomania]

So I opened HD Tune for the first time in forever and one of my disks has a warning error

Does this mean it's basically living on borrowed time?

I've read conflicting info on if it's worth doing any testing on it, some say do it, others say it can cause more damage

The drive is fully backed up so I'm just wondering really if there's anything worth doing/ how long I might have

if its already backed up, try formatting the drive and do further diagnostic tests on it...
