I use a SanDisk titanium cruzer flash drive with my ibook. It's about the length and width of a stick of wrigley's gum, so it sticks out about three inches from the side of my machine. I am always careful not to knock it, but ocasionally it gets touched. Yesterday I bumped it a little and the warning mesage about improper device removal popped up. Then when I tried to unplug and replug, it wouldn't respond. I tried plugging in other devices (printer, external HD, ipod) into the port, but it wouldn't respond to any of them. Tonight I was (stupidly) using the cruzer in the other USB 2 port, when I touched it with some papers which I placed on top of the sleeping ibook. The harddrive whirred, and when I opened the book it was awake, and the nasty mesage about device removal was on the screen. And, you guessed it, now neither USB 2 port works. What should I do? Is this covered by my apple care? Should I deny using the drive? Is this a known problem for ibooks? Please help!
