I am fuming! One of my three external hard drives would kept on ejecting when it the iMac went to sleep and today it quit reading all together. It said the disk was unreadable even thought it had been working perfectly the day before. So, I plugged it into my old PC laptop and it says that it is completely free with nothing on it! I am freaking out. All of my family photos, music, Graduate school work, all missing. Is there any way to get this back to working?
