Comment 19 for bug 433438

i'm having a similar issue since i upgraded to karmic this afternoon. in my case the error is related to a western digital my book. i've used this same my book to back up and store data in several previous versions of ubuntu and never had any problems with it.

kernel: 2.6.31.17-generic

below are the log entries that are generated when i attach the my book:
