Windows 10 Drive Converted to RAW Format, How to Fix It

We've had this happen to some of our client machines within the past six weeks. A perfectly fine Windows 10 PC will no longer boot. The drive changed from NTFS to RAW. CHKDSK reverts it to NTFS; however, rebooting jumps to Windows Repair, where the disk reverts to RAW. I don't know how to fix this problem.

It is possible that the machine's hard drive has failed. So I suggest using EaseUS Partition Master to do a comprehensive check on the SMART status of your hard disk. According to my experience, this tool is very useful for checking disk health on Windows 10. It has helped me several times.

Now, your hard drive has been formatted to NTFS. You can use it now. Hope my answer can help you out.
