I have one of the original WD TV HD Media Players that has worked ok with one of my WD harddrives but recently I attempted plugging in a 4GB usb thumb drive with ( 2 ) 500gb .avi files on it. Both play fine on my PC and I’ve made sure to safely remove the usb drive before unplugging it. The USB is firmly plugged into the WD player and I’ve given it plenty of time to read it. I’ve also tried unplugging everything, waiting a couple minutes, and trying again. Still… “no storage present”. What gives???
Have you tried reformatting the thumbdrive and copying the files again.
Also you are saying that is a 4GB thumbdrive and you have (2) 500GB .avi files. I think you meant to say 500 MB
