That would be number of hours the drive has _already_ been running. IOW, it is telling you that the drive has been on for about two years.
Ah, so the opposite of what I thought? Don't confuse the value from the selftest log with the value from smartctl -a. There's also a value Power_On_Hours in smartctl -a which I figured would be the hours it's on. As I see now the RAW value of it is increasing, but certainly much faster as that it could be counting the hours. Ah, confirmed, I ran a second short test about one hour later and the value in the log has increased by one, so it's indeed the power on time it has had already. Thanks.
The entry that usually tells you if you are developing problems are Reallocated_Sector_Ct. If that is in the hundreds (or even in the multiple dozens), you are probably looking at a drive that is going to fail in the near future.
Offline_Uncorrectable and Current_Pending_Sector are other ones you don't want to see values much above '0' on.
These are all at 253 (raw incidents = 0).
I understand that a drive that looks really well in SMART could still fail next day, but at least there is no indication of that from this side.
