How do I safely remove my CD drive or a USB device when running Ubuntu? If I pop out my CD drive the OS locks up on me really bad, I can't even move the mouse. Also, how do I manually run "dpkg --configure - a"? I was in the middle of an update DL and the computer froze. Now the OS recognizes there are 18 updates left to install but I'm told I have to manually run that dpkg before I can get the DLs.
