However, in case you are unable to restore data from the backup or backup is incomplete, you can check the database errors and fix them using inbuilt utility of Microsoft SQL Server, called CHECKDB. It offers you an option to repair the database errors. Database inconsistency may also occur due to system level errors, like file system and hardware. You are highly recommended to fix these errors before repairing the database, else you may face the same problem again after some time.
When you apply DBCC CHECKDB on your MDF file, a suggestion is provided for indicating what minimum repair option is required to fix all errors. Such messages may resemble the following:
CHECKDB found 0 allocation errors and 15 consistency errors in database 'mydb'. repair_allow_data_loss is the minimum repair level for the errors found by DBCC CHECKDB (mydb
The database repair recommendation is minimum degree of repair to try resolving all the errors from DBCC CHECKDB. It doesn't mean that the operation is capable of actually fixing all the errors and recover SQL database. You should also keep in mind that not all the errors reported by DBCC CHECKDB, where repair_allow_data_loss is suggested, cause data loss.
However, some of the database inconsistency errors can cause severe data loss problems. You must run the repair process for determining if solution of a particular error is going to cause data loss. In order to find errors with a specific SQL Server database table, you can try running DBCC CHECKTABLE tool.
In case you run across database corruption and data loss due to any inconsistency error, MS SQL repair becomes need of hour.
You can easily repair and restore damaged MDF file of SQL Server using SQL Server recovery software. The applications use advanced scanning algorithm to provide assured recovery of all your valuable data.
