I have a 2tb passport portable USB 3.0 that is almost full. I got a good deal on two 2tb passport ultra USB 3.0 drives which I recieved yesterday. I want to use one of the ultra drives for a back up of the full drive. Everything in the full drive in under one folder with several sub-folders. I should be able to copy and paste the folder from one drive to the other ( I have done this many times before with other drives, all WD ) but when I try nothing happens. I have tryed drag and drop, formating new drive,rebooting computer with no luck. However it will transfer subfolders one at a time as long as there is no other subfolder in the first folder. And when it transfers it does it at a little less than half speed of what my other USB 3.0 drives do when transfering from drive to drive. Oh and I have also ran the data lifeguard and it passes every test.
Please can someone help me to resolve this problem. Thank You.
Edit: Sorry I forgot to say I am running Win 7.
