Installed an ASUS AX86U yesterday. Have a 1TB Seagate Passport hard drive connected to router via usb. It took me a lot of searching online but I finally can now see the passport folders in Windows Explorer, and can play the music in them, look at pictures, etc. But when I try to add a folder via windows transfer I get "an unexpected error is keeping you from copying the file" and error 0x80070032: The request is not supported. Any ideas?
