I have the same issue with an Ultra II 480GB delivered yesterday. I thought I would check it out with the Dashboard before I started using it, and was shocked to see it reporting as Poor with the same highlighted issue.
I am at the moment connecting the drive via USB with the intention of copying the Win10 partition from my current HDD.
This issue seems to have only started being reported a few days ago so I wonder if this is a problem with with the drive firmware, the dashboard software, or there is a faulty batch of drives on the market.
I hope we all get a responce from Sandisk very soon
