850X not detected by dashboard in Acasis case

I installed the 4TB SSD drive in a 40Gbps ACASIS external case. The drive works well, just a bit slower than it should (1100MB/s). I opened the Dashboard (4.02.20) to see if firmware was latest and the dashboard does not detect the drive. Is this a known issue?

Many third party external enclosures can prevent Dashboard from recognizing a device. That is likely the case with your enclosure.
