You would be best advised not to run CHKDSK in repair mode on a potentially failing drive. That's because Microsoft is more concerned with maintaining a consistent file system, so it will sacrifice your data to this end.

When a file system becomes RAW, it means that some metadata has become corrupt or unreadable to the extent that Windows is unable to identify and/or mount the volume. Windows then treats the NTFS volume as just a bunch of bits. The most common reason that this happens is that some critical sectors have become unreadable.

I would examine the SMART report. Look for non-zero raw values for the reallocated, pending and uncorrectable sector counts.

    May I kindly request for urgent assistance in my matter. I'm attempting
