I have three Yottamaster FS5U3 none of these drives are getting any SMART data (Picked up in HD Sentinel)
Here's a screenshot showing the controllers in use. I've ticked Unsafe in the advanced setting and still no luck.
HD Sentinel has reported this drive has having 58 bad sectors, thankfully I had it installed but as this drive is in a Pool it would be nice for the trigger to start moving files out.
