WD Elements files copy to device, but erase upon ejecting

I’ve tried several times to copy files and folders from my windows computer to my WD Elements 2tb hard drive. Each time, the file transfer window goes through the entire process, and places the folders themselves on the hard drive. After transfer is complete, I see all of my files and folders on the drive. However, when I unplug the HD and plug it back in, all files are gone and only the folders remain.

Please help…

Are you facing same issue with the WD Elements when you connect this on another computer?

Thank you for the reply! Unfortunately, I only have one PC and that is the one I’m having problems with. I will check tonight to see if my Mac is having the same issue, though.
