The common reason is component death. If people need the files back they get the hard disk into another enclosure and if not they call WD for an exchange.
That message is not unusual but I have not seen it caused by corrupt file systems so I'm leaning to component death.

I've got a 500 GB Western Digital MyBook external hard drive. For some reason it appears to have just stopped working. The light on the front of it is on, but solid on. Normally it goes on and off. The error in the event log is:
"The device, \Device\Sbp2\WD&My Book&0&0090a9d2_c1eb6229_Instance00, did not respond within the timeout period."
What could be causing this?
