MySQL databases are used world wide to store valuable and important data. It is Sun Microsystems product whose database capabilities and functionalities are open source. MySQL data files (.myd and .myi) store all the records in the database in an organized way.

Users perform many transactional activities and different operations like data fetching, insertion, updation, deletion etc. into the MySQL database. Due to all these actions MySQL database and tables are vigorously used and becomes very easy prey of damage and corruption. The corruption or damage can be identified by some mysql error codes like –

• Record was already deleted.
• Incorrect key file for the table.
• ‘tbl_name.frm' has been locked against change.
• Unable to find file ‘tbl_name.MYI' (Errcode :###).
• Record file is crashed etc.

Not only this, sometimes dropping or deleting tables accidentally from the database, lost partitions, mysql delete column table etc. also cause huge loss of precious data’s.

Deleted, corrupted and damaged MySQL databases causes many problems like –

• Damaged and corrupted indexes.

• Locked database.
• Damaged tables and table data’s.
• Damaged stored procedures and views.
• Lost or missing predefined default values and rules.
• Corruption of multi-volume database files.
• Logical issues with MySQL data files.

Recovering the deleted data is bit easy because when any file or data gets deleted or missed only its access instance gets freed but the data remains in the storage media, which can easily be recovered just by using efficient Data Recovery software.

In order to repair the database and to get rid of errors proper and effective repair of MySQL database is needed.
