Yes it's an external usb3 drive. That's interesting and I'll test that tomorrow. I recently commented out a GENERIC kernel the USB debug line because the console was filling up with usb attach messages on boot. They were appearing after the login prompt. I have a couple of usb3 hubs attached and the disk is attached through one such hub. (although it was done this way because sometimes it'd be seen as /dev/da0 and others as /dev/da4. And possibly linked to this, when it came up as /dev/da0 it was always with a usb2 speed rather than usb3). thanks everyone for your input. -- J.
