How can I repair corrupted mdf file?

Recommended Posts

The MDF file is a primary database file in SQL Server that contains the database schema and data. If the MDF file is corrupted or inaccessible, the situation is dire for the user or organisation. Users are unable to open or access their personal data due to corruption. As a result, the user must repair the corrupt SQL MDF file in order to access the data. To resolve this issue, we have compiled a list of the best MDF file recovery solutions. Before we proceed to the solution, we must first determine the source of the corruption so that the problem can be easily resolved.

Resons of corruption of MDF file?

  • If a user has the SQL database compressed in a folder,
  • Any modifications to a SQL Server account
  • The storage medium on which all MDF files are stored has been damaged.
  • The MDF file will be corrupted if the file header is damaged.
  • If the SQL database is used and a network error occurs in the middle,
  • Failure of a hard drive, virus attack, unanticipated power outage, improper system shutdown, and so on.

Repair a Corrupt SQL MDF File Using the DBCC CHECKDB Command
The following are the steps to recover corrupt MDF files using the DBCC command:

  • Execute the DBCC CHECKDB command.
    DBCC CHECKDB (Name of the corrupt Database)
  • Check the index ID next.
    • If the index ID is greater than one, delete it and recreate it.
    • If the index ID is 0 or 1, restart DBCC CHECKDB with the appropriate repair options, such
      as repair rebuild, repair fast, or repair allow data loss.
      DBCC CHECK (name_of_corrupt_database, repair_fast)

DBCC CHECK (name_of_corrupt_database, repair_rebuild)

DBCC CHECK (name_of_corrupt_database, repair_allow_data_loss)
