Since there’s currently a filesystem error, simply restoring the disk image you made will also restore the filesystem error. Like I said above, all you need to do is copy the contents of your games partition to another partition, reformat, and copy back.
As I've seen this a couple of times now, can I just point out that you are missing the crucial step 2 in the procedure.
1. Backup
2. Verify your backup3. Format
4. Restore
Noone wants a write-only backup to be their only copy of important data.
Best regards,
