    SQL error 823 occurs when a read of a page fails at the OS layer hence throws error to the user. The main reason of this exception error is associated with overloaded storage, hard disk going bad, faulty drivers, incorrectly configured disk subsystem, etc. This problem can be solved with the help of external trustful software. So I would like to recommend you to use SQL database recovery software which performs simple steps of repairing SQL database and recover it without any damage. Read More: - http://www.repair-sql.net

    Hi lincoln,

    Have you tried a manual method to repair your corrupt MDF file? If not, then I can suggest you a very effective process. The manual way is to execute DBCC Checkdb statements as a new query.

    The SQL statements which you need to execute are very easy. You can note the statements from this link: Recover data from corrupt MDF file
    Let me know your review.

    There are two methods to resolve this issue:
    Method 1 - Try DBCC CHECKDB command to fix sql error and repair corrupt database.
    Method 2 – Try External tool which helps to fix sql error 823 & recover sql server database. One such external tool that you can use is, http://www.sqlrecoverysoftware.net/sql-server-mdf-file/

    Here is the possible cause & resolution methods for SQL server error 823.

    Cause: Error 823 may occur due to either SQL Server database corruption or I/O errors in the database. The error usually indicates that that there are some inconsistency in file system or the database file is corrupt.

    • Run Chkdsk to find file system inconsistency issues and resolve it.
    • Use DBCC CHECKDB utility to try repairing the damaged database.
    • If the above methods do not help, You need to use third party applications to repair and restore the damaged database.

    First of all back up all the database files and after that you can sun DBCC checkdb statements to safely repair damaged SQL file and recover all the data from it. It consists of 5-6 sql-statements which needs to be executed sequentially. It also contains dbrepair statements which scans and repair inaccessible SQL Server file.
