How come?

Been busy preparing my report of training, my pen drive chooses this time to die. I can't opne it! Ths comp ask me to reformat it, but ALL my report AND info is in the pendrive! I didn't backup, never have the thought that the thumb drive will spoil. And it chooses the best time to die : with all my info AND my report. Have to do everything again. So sad. But I can't do anything, since ths thing is dead, and i can't open any files in it. Have to start all over again. sigh.
