I have a buffalo portable hardrive dont really know the model but it was working fine then all of a sudden stopped and now when i plug it in the light flashes once but it wont work i have tried it in multiple computers and with different usb cables and it still wont work! am i screwed? (really hope i am not)

Then if its under warranty replace it. Its faulty. Its not detecting the internal HDD at all.
