WD My Passport 2tb suddenly stopped working

Hi ,…

i bought my passport 2tb 1 year ago
and it was working perfectly until 3 days ago when it stopped working

 this problem started when i was trying to plug it to my friend Win 8 PC

and now its not recognized even on my pc

when i plug it in , the disk seem to be running but with no pc recognition

the Drive is not recognized in 4 different computers , and i can’t find it using any of the WD programs

i also tried different USB wire 

any solution  ?

i don’t think you can do anything else but if it is still under warranty, send it for RMA.
