    All that appears to say is that there was an issue in the USB mass storage stack. So it was directly caused by removing the device. Can you eject it before removing it?

    i did eject it lol. but usually it just gives me a silly warning about data loss. honestly, how can something like removing a flash drive give OS X such an ulcer? Sometimes Mac OS X just confuses me.

    What confuses me is the warning you mention. Normally, no such warning should be displayed when you eject the USB device then remove it physically. I have used many USB memory sticks that way. Seems there is something wrong with the USB device.
