Have you ever met the case that the external hard disk drive becomes raw when use it? For example:
My WD external hard disk drive shows raw file system suddenly. What’s more, I am asked to format the external hard disk before I can use it. I totally have no idea what is going on. Maybe I should format the external hard disk drive so as to use it normally and to save new information on it. But I do not want to format it right now, because I need to access files saved on the external hard disk drive at the previous time. Will I lose those original files forever if I format the portable hard disk drive? How can I view them again? -Fred
One more similar case:
My external hard disk drive is unformatted. I check its disk properties in order to make it clear what is the problem. The reason is that the external hard disk drive is raw file system, and both the used space and free space are 0 byte. Can I use the external hard disk drive normally after formatting it as the system prompts? There is other thing need to be solved. How can I view files saved on the raw external hard disk at the old time? Please help me if you know any information. –Gaby
