Database corruption in SQL databases can amount to huge losses depending upon the size of your organization. Because of database corruption, you would not be able to access the databases, work on them, and most importantly all the stored records would become vulnerable. But there are certain in-house workarounds that would enable you to perform mdf recovery. However, if these methods do not work then you should use a third-party sql database recovery software to repair the damaged database.

Consider a situation in which you are facing the following error message while working on an MS SQL Server 2000 database:

“Table error: Object ID O_ID, index ID I_ID, page P_ID, row S_ID. Test (TEST) failed. Values are VAL1 and VAL2.”

Cause:

The most prominent reason for this table error is that the a record has failed while auditing as corruption is detected in its record header.

Resolution:

To overcome this problem, there are following methods that you should try, preferably in the given order, to recover MDF file:

Addressing hardware-related errors: You should check and address the hardware-related issues that may have caused the database header corruption. For this purpose, you can perform the following measures:

Check the Application log and Error log in SQL Server to ascertain whether the error has occurred because of hardware corruption. Fix the errors that appear after running hardware diagnostics. Swap the hardware components to isolate the actual reason of database corruption. Reinstall operating system after formatting the hard disks. Restoring database using backup: You should check the status of the database backup. If it is clean and updated, then restore the database using the backup. Running DBCC CHECKDB: You should run DBCC CHECKDB with the suggested repair clause to repair the damaged database.

If you still face the same error message even after performing these steps, that means the database is severely damaged. To perform MDF file recovery in such cases, you should use a third-party master database recovery software. These read-only tools are very safe to use that do not overwrite the repairs on the original database.
