I have the tplink archer 1750 a7(us). if i plug a flahsdrive into the usb i can access it from my computer and i have no problems. when i plug my WD mypassport for mac 4tb hard drive it can see the harddrive but when i click on the folder that it is in the folder shows that there is nothing there. Almost like it cant regonize it or doesnt know how to read it even though it sees that it exist. i specifically bought this router and this hard drive because they were suppose to be compatiable. am i doing something wrong? or does the router have the ability to turn on the hard drive but the hard drive doesnt have enough juice to spin to be read. any help pleasseeee. i talk to tplink for 2 hours and finally they said they dont know. thanks
