In MS SQL Server databases, the records are stored in the form of pages, which are linked to each other in a sequential manner. Because of being linked to each other, the searching and inserting new records is made easy thereby saving a lot of precious time. However, at times the database are unable to exhibit the expected functionality because of database corruption, which can occur due to various reasons such as virus infections, hardware malfunctioning, abrupt system shutdown, etc. In these circumstances, certain in-build methods can be used to recover SQL database. If these methods do not work, then I would suggest to use a third-party MS SQL Server software to overcome such situations. Consider a situation in which you are getting the following error message while working on an MS SQL Server 2000 database: 鈥淭 able error: Cross object linkage: Page P_ID1, slot S_ID1, in object ID O_ID1, index ID I_ID1 refers to page P_ID2, slot S_ID2, in object ID O_ID2, index ID I_ID2. 鈥? Cause: The primary cause of this problem is that the P_ID1 page points to another, P_ID2, page in a different object. Resolution: You should perform the following methods to recover MDF file in these situations: Address hardware-related issues: A lot of times these errors are caused by malfunctioning of the hardware components. You can use the following measures in order to resolve such issues: Fixing the errors that appear after running hardware diagnostics. Checking the Windows Application log report and MS SQL Server Error log to ascertain whether the error has occured because of hardware malfunctioning. Checking if write-caching is enaled on the disks. If yes, then contact the local hardware vendor to get it changed. Swapping the hardware components to isolate the actual reason of database corruption. Reinstalling the operating system after formatting the hard drive. Restore from backup: If the hardware is alright, then you should restore database from the backup if it is clean and updated. Run DBCC CHECKDB: If the backup does not solve the problem, then you should run DBCC CHECKDB with the suggested repair clause. If you still are getting the similar error message even after using these methods, then you need to repair the damaged SQL database using a third-party master database file recovery software. These SQL database recovery tools are able to repair corrupt MDF files without any damage to the existing files. The best SQL database recovery software that restores various database objects including collations, tables, NDF files, stored procedures, etc, is Stellar Phoenix SQL Data Recovery. Supporting MS SQL Server 7.0, 2000, 2005, and 2008, this .MDF recovery software is compatible with Windows 7, Server 2008, Vista, Server 2003, XP, and 2000.
