My new HP Z2 Mini G4 is having problems recognizing a Samsung Portable SSD X5 drive on the Thunderbolt 3 Flexible port. I had an issue with another external Thunderbolt 3 external drive (HP P800) on this system and I had the system board replaced and now it works. I have all BIOS, Firmware, and Drivers updated as per the HP Image Assistant software. This drive works fine on two other systems. Any ideas?
