My passport does not work

I’m sorry to inform you that my passport does not work with the knowledge that my passport lights up. I do not know what the problem is, although he was working for 2 day before, I ask you to help me to the presence of very important files

Hi there and welcome to the WD community.

I would like to know if you have tried to connect the drive to a different computer, or if you have used a different USB cable to connect the device, or perhaps a different USB port.

I did everything as advised me, but it did not succeed.It is now asking me to Format my passport  desk. Do you recommend this , And Is there any program that makes me re-deleted files
