I was given a spare drive that I was going to use as a cache drive and put it in my other server (did not pre-clear it, thought I'd let unraid do it [think it was already formated though]). When I turned my server on I got the little orange balloons one said:

 

unRAID Cache disk SMART health [5]: 10-07-2016 15:56

Warning [sERVER] - offline uncorrectable is 24461

While they are all a bit worrisome, the "uncorrectable" part of the last one really got me.

 

I wasn't sure what to post in terms of logs, so I just posted what I think is the SMART output from Main -> Cache Settings -> Attributes

All this but when I clicked the button along side the "Last SMART test result:" I get "Completed without error" ... Thoughts?

The most worrisome is the current pending sectors of 7892.  Sorry to say, but that drive is toast and should be thrown promptly in the garbage.

 

 

...doh.

 

Ah well. Thanks for the confirmation.
