Absolutely risk-free SQL recovery utility to deal with any instance of database corruption

In SQL server database, the IAM or Index Allocation Map takes 4GB chunks of space from a single file and gives us the result. These 4GB chunks are called GAM intervals and a single IAM page tracks the spaces from it belongs to a single entity entirely. If files are more than the size 4GB or there are multiple files, then there comes the scene of multiple GAM intervals and the need of IAM chains. IAM chain is a linked-list of the IAM pages, which can track the space allocated to an entire large file. Sometimes, due to certain corruption in the database, the IAM pages can not exhibit the desired results. In such cases, you need to look for any SQL recovery utility to retrieve the SQL server database files back.

You may be at the receiving end of the below error message while working on your SQL Server 2000 database:

“Table error: Could not check object ID XXXX, index ID YYYY due to invalid allocation (IAM) page(s).”


From the error message, it is quite evident that any of the IAM pages indicated by different ids has been corrupted.


Run the command DBCC CHECKDB to repair the troubled SQL Server database. Run it without putting any repair clause, so that you can be aware of the level of corruption. With respect to the corruption level, you can give the necessary repair clause.

If the above command fails to repair the database and you are still unable to access the same, then, you can try restoring the database from any previously taken valid backup. But, if backup is not updated or restoration from backup can not be performed because of some unresolved problems, you need to opt for a good MS SQL recovery software to do needful.

These SQL server recovery applications are designed with advanced algorithms to locate the corruption and repair the database efficiently. These mdf database recovery utilities are completely read-only in their operations and retrieves the database objects with their internal structure intact.

The software works well on the databases created with SQL Server 2000, 2005, and 2008.
