I have a 14 TB HDD that recently started showing Current_Pending_Sector errors. At that point, was not running a parity drive, and that was the only hard drive in my system. I had a second identical drive, and made it the parity drive. That finished successfully (took about 2 days). At that point it mentioned there were parity errors and that I needed to do a parity check, which I did. That also finished successfully and took around the same time. I documented that in this post.

 

After that I ran a short SMART test and surprisingly, it passed, which you can see in the attached SMART report

 

Since Monday (7/17/23), I have been running an extended smart self test and its been sitting at 90% complete. As I understand it, the actual checking of each sector of the disk doesnt happen until 90%, so that should rightfully take the longest. But I am approaching 4 days here, and not sure if its actually going to complete, or if there is even an issue.

 

So far, there are no errors at all in my system log, since starting this extended smart test.

 

Its also sort of confusing to me that the disk in question lists a number for the "Errors" column when viewing it on the Main Page under Array Devices, yet its still considered healthy?

That disk has recent failed tests, IMHO it should be replaced.

As long as it wasn't disable, i.e. a write failed, it's considered healthy.
