16 GB Ultra USB 3.0 Stopped Working on my Mac

My SanDisk stopped working this afternoon.  It had been runningly perfectly until than.  Had it for about five weeks.

The Mac Pro will no longer recognize it when I plug it into the USB Port.  I have also tried plugging it into a Macbook Air, my iMac desktop, and my printer.  Still to no avail.

ALSO, when I plug it in, the LED will start flashing rapidly (as if it’s transferring data or something) and continues to do so until I unplug it from the USB port.



Retrun it.

Before returning this which you will probably get a replacement knowing that its new, plug it first on a different computer and see if it’s still the same.
