Hi, I recently bought a simpletech 250gb portable hard drive. I moved all of my music onto it and have been using it fine for a few weeks now. Today I plugged it in and opened Itunes. After clicking to play a song, Itunes said it couldn't find it. I tried to manually locate it, but it's not there. The drive pops up like normal when I plug it in, and lists each of the albums, but when I click to view the tracks in the albums, there is nothing there. Already tried it on my desktop, and same thing. The albums show up, but no song tracks are found. I've been searching for someone who's had this problem, but I couldn't find anything. Help would be greatly appreciated.
