I have a Seagate backup drive that has stored a great amount of my important data. However, yesterday, as I used it on my computer, suddenly, an error message popped pout and asked me to format it before using. And I tried to open it in My Computer and still got the same error. So, I immediately checked its “Properties”. Everything showed normally as before, except that its file system was changed into “RAW”. That seemed to be the issue. Do you have any way for me to fix the “RAW” problem? Is it still possible for me to get back all my backed up data? I really need your help, please!
