How can I resolve Error 1067 if it's caused by corrupted data files?

If data files are corrupted, you might need to restore from a backup. Alternatively, you can try starting MySQL with the `--skip-grant-tables` option to access the server, then run `FLUSH TABLES WITH READ LOCK;`, `ANALYZE TABLE table_name;` for each table, and `UNLOCK TABLES;` before restarting normally. For more severe corruption, consider reinitializing the data directory.
