Try external power if you have a socket on disk box ? Try disk on another known good FreeBSD USB3 card on a tower (my card cost 30 Euro BTW) Or try a power doubler cable (connected via a female to female adapter, which Ive never seen on sale, I made my own by cutting up a dead mainboard), to the USB 3 male to male cable. (for any who dont know, cant omit that cable as USB3 socket on lapop size drives is a different shape, flater, wider. I wonder if it might be taking time dropping back to USB2 speed. if eg you don't have xhci in kernel ? I have all of config -x/boot/kernel/kernel | grep hci device uhci device ohci device xhci device ehci I just havent taken some out yet.
