I've been using my optibay as a data harddrive on my Mac. All of a sudden it's stopped appearing. After restarting a few times it realized that there was something there and asked me whether it should initialize or eject the drive. i chose eject and opened my macbook up to take out the drive. I've tried to connect it via USB to my Mac but it doesn't appear anymore. Has the drive failed or is there any way I could save it?
