I have a strange situation here. I got a new Toshiba P850/04P laptop, there are 4 USB 3.0 ports, 2 on the right and 2 on the left.
When I plug my WD 1TB Passport Essential into the 2 ports on the left, the drive keeps disconnecting and then connecting again, on and off. Sometimes it works well for 1 hour and then disconnects and even shows the "please format your drive" message.

What is odd is:

  1. this WD 1TB Passport Essential works perfectly on those 2 ports on the right side.
  2. It has been working fine on all other PCs and laptops.
  3. Another 500 GB WD passport can work with the USB ports on the left (the ones 1TB can not), also all other devices can work with all 4 ports.

I am really confused! Does anyone know what the problem could be?
