so i bought this hard drive Canvio® Basics 3.0 Portable External USB Hard Drives | Toshiba and i cant connect it to my galaxy tab 2! it says high powered hard drive connected when connected with the OTG. i specifically bought a HD without a power supply to hook up to my tablet. How do i go about getting this to work? Im scared to root cus i dont wanna ruin my tablet. i just wanna be able to put all my music on it since, for some reason, no sd card over 32gb will work.
