F11 and external hard drives

The USB disconnect message is the important one here. It seems very 
likely to me that the Dynex enclosure is the source of the sudden 
disconnect. The USB chipset on the Dynex' circuit board may not be 
working correctly. I find this happens a lot with hard drive enclosures. 
Some of my USB enclosures went dead mysteriously, so I replaced them 
with enclosures from a better-built brand. Try putting the Western 
Digital drive in a totally different enclosure -- one that you know 
works fine. Also, be sure that you are supplying sufficient power to the 
external enclosure.
