Comment 3 for bug 108902

I am having almost the same problem. When I (in gnome, via right click on the desktop icon) unmounts/ejects the drive a message pops up telling me the eject failed, and then the drive is remounted. I Have a Western Digital 250gb MyBook Essensial.

I have been running Feisty since early alpha and this behavior is quite new 1-2 weeks old or so. i.e. Earlier alpha versions of Feisty did not have this bug thus working as expected.
