WD My Passport 500Gb not detectable in My Computer

Dear all,

I need help. Got my first 500Gb My Passport as my 22nd brithday present but this is not a good thing to me as a week later after using it, the harddisc is not detectable in My computer nor any auto-detect being popped out.

Surprisingly, in “Device Manager”, the 500Gb is detectable in the “disc drives”. 

Wonder anyone would guide me with this?



Is it online or offline? What’s the color of the bar next to it?
