Hi,
Can you give some more details? Are these in some kind of enclosure?
What USB speed are they connected at?
If you are using an XHCI controller and the drives are connected at
Super Speed (5.0 GBit), there has been a change in the XHCI driver which
change how short packets are handled for transfers larger than 64K. The
following patch will revert to the old behaviour from a class-driver
point of view:

Do other USB devices connected to the same USB host controller continue
to work?
