my Western digital 500gb my book (WD5000C032) has been giving me some really big problems lately. When I turn on my computer, it turns on with it and everything. It registers with the computer but instead of showing the MyBook icon it shows a regular hard drive icon and it doesn't allow access inside because it apparently isn't formatted anymore. But the thing is, sometimes i works perfectly fine when other times it doesn't work at all. The light turns on and it runs and everything, it only doesn't allow me to access anything inside of it. Someone please help me because i would rather not reformat this drive.
