Hi, This situation sounds a lot like the problems I had when I went from 2tb drives to 3tb -> 6tb drives connected via USB 2/3 to docking stations. 2tb drives worked well. 3tb drives were all screwed up. It turns out that the firmware in the Kwin dual drive docking station could NOT support > 2tb drives. Something to do with the number of bits. I went to SIIG usb3 dual port docking stations and poof, the size of the drive didn't matter any more. The SIIG product has been removed from the market I think. Other issues: fans get noisy after a short period of time and my favorite bug. The drives in a station drop ready (for lack of a better word) under heavy i/o load. I suspect that they still draw power from the usb interface even though they are powered themselves. The drive(s) get busy, draw more power... past a threshold and the drive drops away... the system sees the drive go... i/o stops... the power draw goes down... drive comes back... possibly at a different drive letter... A REAL PAIN.
Most of my big drives are 1 partition but some have several due to performance issues with large numbers of files in a 6tb file system. All systems are various Fedora... I'm on Fedora 25 now... still have the power drop with heavy i/o problem and the performance problem with # of files in one big partition. ext4 fs type and even tried xfs... found bugs... went back. I guess the newer systems have usb ports with > 32bit capable interfaces (I don't think this is the right word though). The interface handles drives > 2tb is what I mean. Hope this helps.
