MS SQL Server is a relational database management system (RDBMS) server that is used by many organizations as backend support. It performs many useful tasks such as defining, modifying, or performing miscellaneous tasks on the database. It uses the.MDF file as its primary database file. However, sometimes the MDF file gets corrupt thereby making the database inaccessible. Such occurrences could happen because of various reasons such as malfunctioning hardware, power outages, virus infections, human errors, etc. In such cases, you should find the cause and apply appropriate method to repair MDF file. If you are not able to do so, then you should use a third-party MDF file repair software to perform.mdf repair.
Consider a scenario wherein you encounter the following error message while working on a SQL Server 2008 database:
“Table error: Object ID O_ID, index ID I_ID, partition ID PN_ID, alloc unit ID A_ID (type TYPE), page P_ID, row ROW_ID. Record check (CHECK_TEXT) failed. Values are VALUE1 and VALUE2.”
The root cause for this problematic situation is that the a column in the row has not cleared the condition in the CHECK_TEXT statement.
To resolve the issue, you should to perform the following methods, in the given order:
Look for hardware issues: You should check the hardware settings and run hardware diagnostics to ascertain if there is any hardware problem. You can also check the error logs to get the cause of the error. In addition, you can consider reformatting the hard disks and reinstalling the operating system.
Restore from backup: If the problem is not hardware specific, then you should check the backup of the database. If it is updated and clean, then you should restore the database with its backup.
Run DBCC CHECKDB: You should run the DBCC CHECKDB command without any repair clause to determine the corruption level. Then, run this command again with the suggested clause. However, if you are not sure about using this command then you should not use it.
The aforementioned methods would be able to solve the problem. However, at times it may happen that the error reappears or does not get solved in the first place. In such cases, you should use a third-party MDF repair software to solve the issue. Such MDF file repair tools are able to repair MDF file without overwriting the existing file.
