My new My Passport Essential needs the oporating system reinstalling!

My new My Passport Essential was formatted by accident hence there is now nothing on it. It needs the Oporatng System reinstalling if it is going to be of use. please help !!!

I’m in the same vote mine was erased for added room by the previous owner and keeps going to sleep after about 10 minutes its driving me nuts

I suppose that you are referring to the WD Smartware application, if so, please visit the link below, it will teach you how to recover the software:

what I’m refering to is when you run the the virtual drive with the smartware iso that is built into the drive it says the operating system is missing on the hard drive and will not recognize the external hard drive

just a bump 

any one know what to do?
