The PFS (Page Free Space) pages in the MS SQL Server databases are used to search for free space in the database tables. It holds a byte-map which contains one byte per page that is represented by P_ID. Sometimes, you are unable to read the PFS page that can happen due to database corruption. The corruption cases are caused due to various issues such as abrupt or improper system shutdown when the database is open, virus infections, etc. In such circumstances, you should try to recover SQL database using appropriate methods. If you are unable to workaround the issue, then you should use a third-party SQL database recovery software to address the problem.
Consider a scenario wherein you are facing the following error message while working on an MS SQL Server 2000 database:
"Object ID O_ID, index ID I_ID: Page P_ID could not be processed. See other errors for details."
Cause:
The most prominent cause of this problem is that the P_ID page was marked as allocated in a PFS page. But, when the page was read, the reading failed resulting in this error.
Resolution:
To resolve this problem, you would need to use the following methods ideally in the given order:
Resolve hardware-related problems: You should try out the following measures to fix the hardware issues that may have caused this problem:
Check the Windows Application logs and MS SQL Server Error logs to see if the error has really caused because of hardware corruption.
Fix the errors that occur after running hardware diagnostics.
Try to swap the hardware components to see if the error is reproduced or not.
Reinstall the operating system after formatting the hard drives.
Restore from backup: If you are unable to find any hardware-related issue, then you should check the status of the database backup. If it is clean and updated, then you should restore the database from the backup.
Execute DBCC CHECKDB: Lastly, you can run the DBCC CHECKDB tool with the suggested repair clause to repair the damaged database.
However, if you still are getting the similar errors then you should repair the damaged database using a third-party master database file recovery software. These SQL recovery tools are extremely non-destructive in nature that do not damage the corrupt database any further.
The MS SQL Server recovery software that is recommended by most database recovery experts is Stellar Phoenix SQL Data Recovery. With the capability to recover various database components including tables, NDF files, collations, stored procedures, triggers, defaults, etc, this.MDF recovery software is supported by MS SQL Server 2008, 2005, 2000, and 7.0. Also, this MDF file recovery tool is compatible with Windows 7, Server 2008, Vista, Server 2003, XP, and 2000.
