MDF file is the primary database file. MDF stands for “Master Database File”. It is associated with the SQL Server for storing automated data, including schema information. It also generates a database file, NDF, which stores data without schema.
MDF file is the most essential file as it stores all the important information in SQL tables. If your SQL MDF file gets damaged for any reason, then your whole database can be corrupted. Before discussing manual and professional methods to repair corrupted MDF files, let’s first explore the key reasons why it occurs.
In an SQL server, the primary database files are the MDF files. So, there can be multiple reasons behind the corruption. MDF file format stores users’ data, so ultimately, manipulation can affect the entire database. Some of the major common reasons are:-
If the MDF file is damaged, the SQL database cannot be accessed. A user accessing a corrupt SQL database may see several error messages. Therefore, the database administrator is accountable for acting quickly and preventing data loss.
Let’s further examine the free method for resolving the problem now.
The manual Recovery Method is known to be the free solution to repair corrupt SQL MDF files by using the SQL Server Management Studio (SSMS).
Follow the instructions below to repair the corrupted MDF files in SQL Server by running the DBCC CHECKDB command. These are as follows:-
DBCC CHECKDB (Name_of _corrupt _database)
Further, Look for If the Index ID >1. If yes, it is, then drop it and create it again. If in case the Index ID is 0 or 1, then run the command DBCC CHECKDB as mentioned below:-
DBCC CHECK (name_of_corrupt_database, repair_fast)
DBCC CHECK (name_of_corrupt_database, repair_rebuild)
DBCC CHECK (name_of_corrupt_database, repair_allow_data_loss)
This free solution usually works well to repair corrupted MDF files without any obstacles. However, this approach is not as smooth in all cases. Sometimes, it fails at a certain level. However, manual methods possess certain limitations. Let’s further discuss these limitations in more detail.
Multiple drawbacks make the manual method a bit risky. These are as follows
