I'm not sure what update changed things, but somewhere along the way I lost SMART on my USB2 ProBoxs, and my USB3 (H82-SU3S2) ProBox slowed to USB2 speeds. I found a few posts here about re-enabling unsafe DirectIO to get SMART reading working again, but I can't find any new info on the USB3 problem.
Previously in SB Scanner, the Bus Speed (Disk details) of a drive in the USB2 enclosures would be ~86 MB/s and drives in the USB3 enclosure would have been ~600 (I think). Now they all read as ~86. I didn't ever write down the Bus Speed of the USB3 enclosure, but I was checking those numbers to set balancing rules in DrivePool, so they were different in the past.
UsbTreeView shows the H82-SU3S2 connected over USB3, but transfers are SLOW now. No drivers have changed, only Windows security updates are allowed to install. Did anything change in DrivePool or Scanner?

EDIT:
New development, now the H82-SU3S2 has started disconnecting from the PC once or twice a day. Unplugging and re-plugging in the USB cable to a different port gets it back into the pool.

Hi folks,
