Wd red 3tb raid1 SMART ERROR

Hi to all the community…

i’m using 2 hard drive wd red 3tb in raid1 in my nas with ubuntu 14.04 lts

After a power loss last month smart log say me that there are many errors in my disk.

I also formatted the disk, surface test and recreate the arraid but the error are still there.

Hope someone can help me to understand what kind of error are that…

Thanks in advance… Bye

Unfortunately, a failed SMART test indicates the hard drive is not healthy and should be replaced under warranty.
