Is it out of the question to discard the enclosure as too bugged to use? Otherwise, there is a small chance that the vendor has a firmware update that isn't stupid. Or maybe even a jumper in the enclosure. Reference: http://forum.hddguru.com/viewtopic.php?t=21099&start= has some information which might help.Received on Sun Nov 03 2013 - 05:37:32 UTC
