One of my drive show 14 errors. I run a SMART test and this is the logs. What does it means? The drive still green btw.

 

Thanks.

Please post the complete SMART report or better yet the diagnostics.

Here are my diagnostics

Disk has pending sectors and failed the SMART test, it needs to be replaced.
