I have a 2.5 "Portable Hard Drive I am trying to download the files with an R-Driver III USB 2.0 SATA IDE cable. When I right-click My Computer then click Manage indicates that it unreadable and unrecognized. As I can here the disk, it is necessary to connect to a power source for a 2.5 "drive? It's getting hot. Please help!
