I do manual, not automatic, Time Machine backups, while running Lion and using an external hard drive attached to my iMac. When the backup completes, I right-click on the icon representing the hard drive and select ‘Eject G-Drive Mini’. However, then I get the message ‘The disk “G-Drive Mini” wasn’t ejected because one or more programs may be using it’ It then gives me the option of doing a ‘Force Eject’ of this drive, which I then sometimes do. But my question for the forum is: how can I find out what program may be using the G-Drive Mini? Since it is done with the time machine backup and since I have closed that preference pane, I doubt that Time Machine is still using the external drive. Game ppsspp ultraman fighting evolution 03.
