Help me please

I have 3 my books that have suddenly stopped working.When I start up the computer and the my book drives are connected I get a blue screen for a few seconds,then directed to a start up repair program.This does not happen when the my books are disconnected.I have ran all the diagnostic tool programs that came with my computer,but they only cover the computer nothing external.I am currently running windows vista,could this be the cause of the problem with the updates that are automatically installed ? I can understand 1 drive going down but 3 at the same time ! Any help would be greatly appreciated.
