MDF files are typically stored within an SQL database. The SQL database will typically store thousands of different records and will continuously expand its size every day. Companies will use SQL databases to perform updates, modify operations, and alteration. This work done on the database will result in inconsistencies and these inconsistencies can result in database corruption. To repair a corrupted Microsoft SQL database file, the basic MDF file will need to be repaired. This is important because the MDF file is the primary SQL database file.

Typically, the best way to start off with MDF file repair is to start with Method 1, the manual method, which does not involve any additional software in order to repair the MDF file. If that does not work, then the next step would be to move on to Method 2 and finally Method 3. When an MDF file is corrupted one of these three methods is usually successful in repairing the MDF file.
After the MDF file is repaired the SQL database should be repaired as well. If the SQL database is not repaired then you may need to locate other MDF files or proceed to an SQL database recovery tool that will process all the files within the SQL database and determine what the problem is. This part of the process could be very lengthy and time-consuming and it is recommended to attempt to repair an MDF file or multiple MDF files before starting with a full SQL database recovery.
