Either way, smartctl is not going to be really useful with this drive. > -- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller(a)deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/

It might be interesting to see how 'lsusb' identifies the interface chip, though, to see if it happens to be one that version 5.39 knows how to handle. -- Bob Nichols AT comcast.net I am "RNichols42"
