About how to format the mobile hard drive in RAW format in windows 7

About how to format a mobile hard disk in windows 7 in RAW format, I don't know how to solve the problem. The E and F partitions of the mobile hard disk are always unrecognizable and always prompt formatting, there are a lot of important things in the two disks,
I don't want to format it. I want to see how it can be solved. I checked disk management and found that both partitions have become RAW file systems. The main idea is to change RAW to NTFS format. www.2cto.com first tries to enter the cmd command line and run convert E:/fs: ntfs and convert F:/fs: ntfs respectively. After running the command, I found that the result was not changed, you need to perform a disk check: Then run chkdsk E:/f and chkdsk F:/f to check the scanning progress. The results will be gratifying as the two disks finally come out. to sum up, it is estimated that this is the bug author Samir of win7.
