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
Hope this helps.
