I have a laptop with Windows Vista Home Premium. I also have a desktop pc which runs on Windows XP. I have a external usb hard drive that works quiet nice in Windows Vista. I use it for backup and data transfer. I am trying to sync my old desktop with Vista. In XP I had installed iTunes and there are quiet ample of songs in it. I had copied them on the drive and when I connect my drive to usb, Vista cannot play songs from it. It shows me a error it is not able to access the file. What should I do know. Most of the time this drive works fine with Windows Vista. But now it is not giving a nice response. How can make all my audio access to Vista system through this external drive. Is this issue related to drivers.
