There are reports that USB 3.0 drives may not work. Be sure the drive is not locked by encryption apps on the PC too. For me I make sure by removing all partitions on the new HDD and creating a single volume then format it. Use the Quick Format too.
I have a Samsung smart tv (model no. UN40EH5300FXZA) and I used to watch movies I had put on my external hard drive (A WD My Passport 500G Hard Drive) by connecting it to the USB port on my tv. I just updated my external hard drive today, to the WD My Passport Ultra 1TB Hard Drive, but it will not register on my tv or Blu Ray player (also a Samsung).
I am not very tech savvy- enough to figure out I could put movies on a hard drive and watch them on my tv, but not much more than that.
Could anyone explain to me why it will no longer work? I thought it might be something with the USB 3.0 stuff? but on both cords there is a sticker stating each hard drive was USB 3.0 and USB 2.0 compatible. If someone could explain it in the simplest terms possible, I would really appreciate it. Especially if there is something I could do to fix it.
