This appears to be a bug with Dashboard 22.214.171.124. Dashboard 126.96.36.199 discovers the drive fine. My OS is Windows 10 x64.
I picked up a WD Blue 250 GB SSD. It is installed and running my OS (Windows 10). Obviously the bios sees it. Windows sees it. Disk management sees it. However, dashboard does not see it. The drive is set to AHCI and solid state drive in the bios.
Is there some other trick to get dashboard to see the drive?
