How to troubleshoot the Error 7906 in damaged MS SQL Server 2008 database

MS SQL Server 2008 is an RDBMS (Relational Database Management System) from Microsoft that is used to provide enterprise solutions. It is fast, reliable, secure, and scalable to name few of its salient features. However, as nothing is perfect in this world, it can get corrupt due to few internal as well as external factors. These corruption issues can be sorted out using some corrective methods. If none of these succeed, then the use of a third-party SQL recovery software is the best suggestion that I can give.

A similar situation may occur while you work on the MS SQL Server 2008 database in which you get the following database error:

“Database error: The file 'FILE' is not a valid Filestream file.”

Cause:

There is a 'File' file in the Filestream dataspace that is found in it whereas in ideal circumstances few specific files such as 'filestream.hdr' are found under it.

Resolution:

To resolve this erroneous situation, one must work out some method to perform SQL Recovery. Some of these methods can be followed in the given order:

• Address the hardware-related corruption issues: Quite often such issues are caused by faulty hardware parts. For this, you should perform the following measures to recover the damaged database:

  • Swap the hardware parts in order to check and focus on the actual reason of database corruption.

  • Run hardware diagnostics and try to eradicate whatever errors are resulted.

  • Check the error logs and see whether some problem has occurred due to faulty hardware parts.

  • Check if there is write-caching enabled on your hard disk controller. If yes, then contact the hardware vendor to replace the hard disk.

  • If nothing works out, then perform a reinstall of the operating system after the hard disk format.

• Replace the database from the updated backup: However, if the hardware is safe and sound then check and analyze the status of the database backup. If it is up-to-date, then replace the database with the clean and updated backup.

Now, try to check if the error appears again. If the problem is still persisting, then you should use a third-party SQL database recovery software to recover the damaged database. Using these non-destructive SQL recovery tools ensure that the recovery is safe and secure.
