There was a blackout in my home and my computer's hard drives' filesystems were corrupted.
I checked the system files and the hardware, and found no problem. But I did the stupid thing of running chkdsk /f X: first and it had found and deleted corrupt attribute records from 16659 files.
Now I think all these files may be corrupted.
I took ownership of the "System Volume Information" folders and found the complete logs inside the Chkdsk folder there.
And I use nfi.exe to get the affected files from the sector numbers. I am trying to write a program using asyncio.create_subprocess_exec to do that.
But first I want to understand the output of nfi.exe.

What is $DATA (nonresident)? Does it mean the metadata and filename are kept but the data of the file is gone, the file is a "ghost file"?
I tried to Google search "$DATA (nonresident)" and found absolutely nothing about its meaning.
