WiredTiger.wt, connection: read checksum error for 4096B block at offset 53248: block header checksum doesn't match expected checksum

Hi,

I'm using MongoDB 3.4. We are unable to start with the backup files of /data/db.

As per the documentation, tried to repair DB with the following command but same error persists.

mongod --repair --dbpath /db-path

I have attached the log file.
