been doing the same as this for years, I constantly have problems once I insert the usb disk that contains my keychain, that if i attempt to eject it safely, it says i have to quit effectively every program on the computer before it will alow me to eject it ? and sometimes it even wants me to quit the finder to eject it, so I end up force ejecting the usb disk, the problem is the dialog that comes up and says I have to quit programs before I can eject the usb disk. Gives no indicator as to which keychain item is causing this issue, I have 400-500 keychain items so its a drag to establish where the problem lies, ever experienced the same … any ideas ?
