[Thunder3 RAID Station] Why is my SD card not recognized on macOS?

In some cases, the SD card is not recognized after restarting macOS when a USB device is connected to the Thunder3 RAID Station at the same time. To fix this problem, please update the firmware of the Thunder3 RAID Station.

As a temporary work around, disconnect any USB devides that are connected to the Thunder3 RAID Station, unplug the power adapter and then reconnect it while the SD card is still inserted into the card reader.
