Edit, I tried using the latest snapshot bsd.rd and the device is still detected.. but the same error occurs..
I know it's "trying" to write, each time I print q in the fdisk interface.. the disk status light flickers.. could the device just hate non-USB 2.0 controllers?
(Crap, It seems to work perfectly fine on a system running Windows 2000.. With a USB 2.0 controller.. *Sigh*)
Do I need a new enclosure?
