While InnoDB tables are more resistant to getting corrupted than MyISAM tables, the InnoDB tables can still turn corrupted and cause server crashes. You can perform a complete database restore from a recent backup copy. However, you may lose hours of data if the crash happened before you took the last backup. If you don’t have a backup, you can try force start MySQL Server by running ‘innodb_force_recovery’ with a value set to 1 to 6. However, using innodb_force_recovery with a value greater than 4 could corrupt the data files. A better alternative is to use a MySQL repair tool to repair corrupted InnoDB tables without the risk of data loss. Here, we’ll review how Stellar Repair for MySQL software can help you fix InnoDB table corruption.

In my case, I selected the MySQL format.

Note: For saving the database of MySQL version 8.0, you must have MySQL 8.0 ODBC driver 32-bit pre-installed on your machine.
