No writeable smartware partitiion found on my Elite

Help needed with above message appearing when I connect my Passport Elite. I tried to use it to boot up a dead laptop hd and I think I may have erased it accidentally. Is there a download to restore to factory settings? I’ve only had it for 2 weeks =/

I saw a response on here for the same error telling someone to format the disk in disk management but where do I find that? 

Thankyou for any help

All you need to do it re-format using Disk Manager/Windows or Disk Utility/Mac.

Once you do this, WD SmartWare will recognize the drive again.
