nMicrosoft SQL is a relational database management system that is widely used in organizations to store data for customers and for accounting etc. MS SQL Server database is designed around the tables, each having several columns. SQL Server uses MDF file to save the records, views, triggers, primary keys, foreign keys, indexes and other SQL database components. But at times, operating system errors and hard drive failure like events might prevent you to access this file containing various records and other related information.nSQL server data loss can occur at a number of different levels. The first level of data loss starts with the storage device. The next level of data loss starts with the file system level. The information about where data files are on the volume can also get damaged or corrupted. The last level of data loss can occur within the file itself as the MDF files are prone to corruption because of its complexity. The internal structure can get corrupted at any point of time and makes the table data inaccessible.nEveryone knows the fact the data that resides inside an organizational database is valuable. For the smooth functioning of the organization, information stored in SQL server is so crucial that SQL server or SQL database corruption compel every organization to find out the solution that helps in getting back the data stored in the SQL server.nCommon MS SQL server error messages pops up when the database records containing MDF file gets corrupted:n
