[Fixed] MySQL Incorrect Information in File Error

Several MySQL users have reported about receiving the 'Incorrect information in file error' when restarting the MySQL server after it crashes due to a power outage or other reasons. However, the error may also occur due to a problem with the 'my.cnf' configuration file. The complete error message appears as:

ERROR 1033 (HY000): Incorrect information in file: '.*.frm'

Methods to Fix the MySQL 'Incorrect Information in File' Error

The following are five methods to repair corrupted tables and fix the 'Incorrect information in file' MySQL error.

Note: If the storage engine of the corrupt table is MyISAM, use methods 1 and 2 to repair the table. If the table is using the InnoDB storage engine, skip to method 4.

Method 1 – Run the REPAIR Command with use_frm

To fix corrupt MyISAM tables, run the following command:

repair table tbl1 use_frm;

Here, tbl1 is the name of the table that needs to be repaired. Replace it with the name of your table you want to fix.

Method 2 – Drop and Recreate the Corrupt Table

To do so, follow these steps:

  • Stop the MySQL server instance
  • Backup tbl1.FRM (table structure), tbl1.MYD (table data), and tbl1.MYI (indexes) files.
  • Drop tbl1 table
  • Start the MySQL server
  • Use CREATE TABLE statement to recreate the table (i.e., tbl1 in our case)
  • Stop the server once again
  • Copy the MYD and tbl1.MYI files into the database directory (datadir)
  • Restart the MySQL instance

If this doesn't help resolve the issue or there's a lot of missing data in the table, skip to the following method.

Method 3 – Restore from Backup

If the above repair methods don't work for you, restore the MySQL database from the most recent backup. Restoring a backup is the only option when it comes to recovering data from a corrupt table running on the InnoDB storage engine.

If you don't have a backup, using a professional MySQL repair tool may help.

Method 4 – Correct the Configuration File

Sometimes, the MySQL server may start with the wrong configuration file (my.ini for Windows and my.cnf for Linux OS) resulting in error 1033. Such a situation happens when a script – that automatically adapts to changes in the my.cnf file when the data files are downloaded – fails to start. The size of an InnoDB ibdata1 file might not match with the downloaded file.

For instance, the my.cnf file contains the ibdata1 file of size 2GB but the size of the second data file is 4GB.


To resolve the issue, shut down your server and correct the above line in the configuration file to:


Save my.cnf file and the tables will be restored to a working state.
