You should always see the "USB disconnect" message; it comes straight from the kernel. If it's not there you almost certainly have a hardware problem (bad device, bad cable, bad connections, or bad controller). > Another detail that may help.

Can you unmount it from the command line and then mount it again?

What about the "USB disconnect message", did that show up? It's true that the internal cables and connectors used for the front USB ports often aren't very high quality. > 2.
