Hello I have an external hard drive, it's been working fine and i have all of my mac info backed up on it. Also i have lots of windows stuff on it. All working fine without any issues... Until. With no reason it will not mount, there is power going to it and the lights are on and it's turning over but i cant seem to access it in OSX, it works fine in vista. I haven't formatted it and i havent lost any information on it. I hope someone can help!
