Updated by Tim to Data Recovery Tips on June 24th, 2021

I upgraded my computer from Win7 to Win 10 and I have 2 hard drives: one is "C" that has OS and one is "G" that has many pictures and videos, etc. Both drives had an NTFS file system. But after the upgrade, my "G" drive becomes RAW while "C" drive appears okay. I've heard that I can format this HDD from cmd to fix this RAW issue, but I just don't know how. Please help me is there any Command Prompt to convert RAW to NTFS without losing data?

When googling things about the RAW file system, you may notice that some results said that Command Prompt can convert RAW back to NTFS. But a few mentioned that you will lose your important data if you fix RAW drives by directly converting RAW to NTFS. Therefore, to be supplementary, this article will go in detail about how to convert RAW to NTFS without losing data when you use the Command Prompt.

Solution 1: Repair the RAW drive with CHKDSK command

But usually, it will fail and you will get the message "The type of the file system is RAW. CHKDSK is not available for RAW drives."
