We can't know the future for this drive. Today's drives are made to have zero bad sectors as the drives map in spares and more. I must avoid a deeper discussion about how that works but when a drive fails to the point it is showing bad sectors to the OS then you know to not trust it.
That is, backup now or don't complain later.
I ran chkdsk /r on a Windows drive that detected a couple bad sectors. (Windows was freezing)
It notified that it found and fixed all errors successfully.
My question is, how long could this fix work for? What are people's success rates with this when ALL bad sectors ARE fixed?
Because my understanding is that bad sectors could spread causing even more drive failure. Alternatively could a bad shutdown or power outage cause bad sectors, therefor causing the drive to still be good in all other areas? In which case a chkdsk /r would be a permanent fix.
