1TB WD Elements No Data/Unsupported device

I have 1TB WD Elements external hard drive .It was working in my laptop and the usb port in my home theater .

And when I rearranged my movies ,photos ect  the hard drive stopped working on the home theater saying “no data” and “unsupported device”.

But it still works fine on my laptop.

Could I have accidently moved a driver or something when rearranging the files?

Thanks
