Hi Livia:
It seems that we have the ssame problem. My Western Digital Portable passport stopped working all of a sudden. I caanot retrieve my information. I started asking around and it seems that this is a very cmmon big problem with this type of electronic device.
I learned my lesson and from now on I will save my files in more than one place. All I can tell you is to contact tech support.
Good luck.
I will do the same.
