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. 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 convert RAW to NTFS directly. 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
