SQL Server is the most preferred relational database management system of the users which is highly efficient and reliable in managing critical data of organizations. SQL Server provides many advantageous features to its users. One such feature is the use of filegroups; this feature is used to group database files to provide better allocation and database administration. Being a system administrator, you can use filegroup to assign indexes, tables or image, text or ntext data from a particular table to newly created filegroups for each hard drive in the computer.

But sometimes, the process fails to perform table for check and shows the invalid state of a specific filegroup which simply means the server table is damaged. In such a situation the best way is to restore the data with the help of available data backup. In case you don’t possess backup, then there are other ways of fixing the SQL Server corruption.
