Since upgrading to ML, external drives refuse to eject

[tyrell456]

I've had this problem with two separate external USB drives (my Time Machine backup drive and a different one), and also my USB Flash Drive. Every time I try to eject any of these drives, I get this dialog box:

This happens every single time with every external drive I've tried, even if I mounted the drive and then immediately attempted to eject it without using it in any way. If I hit "Force Eject," it claims that it has been ejected, but it still remains mounted and gives me the error dialog box when I remove it that I have removed a drive without ejecting it. I haven't been able to correctly eject a single drive since the OS upgrade.

Does anyone have any ideas about how to figure out what's causing this and how to get it to stop?

Like the dialog says... "something" is using the drive. It may or may not be TM but something definitely is. (Is spotlight indexing them?)

Before you eject, look at all your apps in the dock and make sure none of them are running.

Spotlight's not indexing them, as the Spotlight icon doesn't have the dot in it, nor does the drop-down menu say that it's indexing anything. I've also tried this from a clean boot, with absolutely no apps running and it still does it with every single external disk I've inserted.

It's definitely a ML bug. I raised it with Apple prior to ML GM but it never got fixed.
