Short, boring story: My boss's niece's grandma passed away, and she inherited a camcorder (newish model) she didn't know how to operate, and sent it on to him. The 'corder can save to either flash-sticks or burn to minidisks. My boss popped the minidisk into his 20" iMac....and you can guess the rest: Stuck minidisk.
-- Is there any way to get that stupid thing out without completely tearing the machine apart? (The Esc trick doesn't work, because the iMac isn't even aware there's a disk in the drive.)
