I've got a ton of music on flash drives that I use on my 13 SHO, the other day I purchased a Toshiba Canvio Connect II 1TB Portable Hard Drive, (HDTC810XR3A1) off Amazon to transfer all the music to 1 device, but when I attempted to play from it, the USB device was not recognized. Beside the music files the external hard drive has a "MAC Driver folder" and a "NTI folder" for backing up computer files. Is it as simple as removing those two files to allow Sync 2 to use the device or is the infotainment system just not going to be able to see and use the external hard drive? Work arounds?
