I bought a WD 4tb black drive back in 2015, and the drive has a 5 year warranty.
The drive seems to be working, but recently the smart info started showing current pending sector count=1, and uncorrectable sector count =1.
Whenever I have had this error with other drives in the past, the drive has failed sometime after. The value '1' is quite low though.
It is an interesting question though, because the drive is still working but showing these smart attributes that indicate the drive is failing.
I wonder if I can return the drive under warranty based on the smart attributes? Even though it is still working now?
