  • As we know the MDF files are the primary files used by SQL Server to store database information. If an MDF file becomes corrupted, there are a few methods you can take to attempt repairs:

    Method 1. DBCC CHECKDB
    This command checks the physical and logical integrity of all objects within the database. It is often used to identify and fix minor corruption issues. Run this command first to see if it can resolve the corruption:

    DBCC CHECKDB ('DatabaseName') WITH ALL_ERRORMSGS, NO_INFOMSGS;

    1. Restore from Backup
      If you have a recent backup of the database, restoring from the backup is the most reliable method to recover data. Maintain regular backups to mitigate the risk of data loss in case of corruption.

    3. Using Third-Party Tools
    If the above methods fail or the corruption is severe, specialized software tools can be helpful. While DBCC CHECKDB works well for minor issues, more advanced corruption may require third-party tools like Stellar Repair for MS SQL. These tools can handle deeper corruption scenarios, but it's important to use them carefully to avoid potential risks such as data loss
