Comments from IRC:
drive has one bad sector, now it remapped. (Reallocated_Sector_Ct. ID #5)
Hardware_ECC_Recovered could be also sign of overheating though.
and probably Soft_Read_Error_Rate
I will swap out this drive, hopefully today. :)
FYI, this drive had a loose cable. I replaced it with a better connection.
