I have an external USB Western Digital disk I use for Time Machine backups.
I eject the disk, the disk icon disappears. I wait a few minutes, then unplug the disk. I end up with a "The disk was not ejected properly" error message. Disk Utilities show the disk, but as unmounted. I have the following entries in Console as I plugin the disk, eject it, and the remove it:
