My Passport Ultra not detected

Hi guys i’m terribly low that My Passport isnt detected , i cant access files :mansad:. It has lot of valuable data i need to access. It shows as following images. What can i do to regain access? Its still under warranty though. I hope you guys would be kind enough to help me out.:smiley: I’m anxious as i cant access the data i need to study and work.

 Its still under warranty though. 

Hey guys is the problem too intricate to address or what is it? Can you please clarify so i would know what direction to take? Data is indispensible and  i need it soon. An y help would be appreciated
