3tb Essential now Unknown and Not Initialized

I’ll add to this list.  hopefully somebody will find a reply.  Bought this My Passport in mid December - downloaded information from a dying laptop, which could see the drive.  Now trying it on my new machine and I can’t get to any of the data.  The drive is shown as Type: “unknown” and status “not initialized”.  However it IS initilized and was format before use.  The data was readily readable/writable on the old defunct laptop. 

Have wasted a lot of spare time over three weeks trying to get the thing to work.  Currently extremely disappointed with WD.
