So I try to unmount a disk, and it comes back with the error that it can't do that because some application is using it. You can force eject, but you are warned that that can compromise the data on the disk. OK, so I close all applications, try again to dismount, and I STILL get the error. OK, so I relaunch Finder to let the machine screw it's brain back in and I STILL get the error. Now, I had just backed up onto that disk with SuperDuper, so I just forced an eject, and backed up on it again. After that second backup, it ejected fine. Um, why? If all applications are closed, how can an application be using that disk? More to the point, how do you dismount a disk safely if it refuses to do so?
