Unreadable/uncorrectable sectors - is the HD toast?

I am getting SMART test (short) alert of having 5 Currently unreadable (pending) sectors and 2 Offline uncorrectable sectors on one of my drives.

Here is the full read-out. I am relatively new to NAS. Can someone scan through this and let me know if it’s time to replace this disk? Thanks!

It is indeed time to replace it. If not mistaken it has been online for 1.5 years - might be even worth to RMA.

The drive is not that old, so I would RMA it and replace. 3 failed short test would have been returning for replacement in 3 seconds.

WD warranty covers this disk? I think it’s an old HDD (at least >5 years old) although I have not used it much in the past.

Hard to say - we were just going off of power on hours. I think WD has a warranty confirmation thing on their website that asks for the SN# & country of purchase.

That’ll give you a better idea on if you can RMA.

…Either way, replace asap.
