I have a really big critical problem.... my computer freeze with an external attached to it while it was on. I shut down my computer manually because that was the only way i could. When i turned the computer back on it didn't see the external at all. When i tried plugging it into another computer it said that the drive had to be reformatted. Is there any way to get my stuff. I really can't lose any of this data. If anyone can help please post.
