That's the model number of the Samsung TV that I bought: UN43MU6290FXZA. I cannot find in ANY literature what the maximum volume size is for drives attached to either of the USB ports. I need to know how big an external USB drive I can hang off this TV that will be fully recognized. Also, I am interested in knowing if there is a file or directory count limit. How many files can I have on an external USB drive attached to this TV which will ALL be accessible? Thanks for your help!
