This appears to be a bug. After you select an external drive for use as a Time Machine volume, the drive can no longer be unmounted or ejected. This is even true after you turn the volume back into a normal drive.

Solution: Set Time Machine's backup disk to "None", and then either reboot, or just yank the drive if you're in a hurry (not recommended). When you come back up, the drive should be unmountable.

Yes, I realize that you can always manually "unmount" the drive by yanking the cable, but if you need to get in there with Disk Utility to repair or partition the drive, you'll be unable to, unless you go through the solution discussed above.
