    Sql error 823 occurs when a read of a page fails at the OS layer hence throws error to the user. The main reason of this exception error is associated with overloaded storage, hard disk going bad, faulty drivers, incorrectly configured disk subsystem, etc. This problem can be solved with the help of external trustful software. For example SQL Server Fix Toolbox

    Also you can try these steps:

    • 1 Insert the SQL Server Installation disc into the server computer's disc drive. Access the drive from your computer by clicking "My Computer" from the desktop and double-clicking the disc drive icon.
    • 2 Run setup.exe from the SQL server installation disc. The setup command should be located in the disc's root directory. Run the setup program by double-clicking "setup.exe." This will bring up the SQL server installation center page.
    • 3 Click the "Maintenance" button located on the lefthand side of the navigation window. Select "Repair" and then choose the language you wish the program to be presented in after installation. Click "Next" to continue. This will run setup routines, making sure your computer has all the prerequisites installed to correctly run SQL server 2008. Click "OK" or "Install" to continue. This will bring you to the Select Instance page.
    • 4 Select the instance you want to repair. This will reconfigure your server using automatic backups to a time the server was working correctly and reinstall any corrupted information. Click "Next." The repair rules will automatically verify the operation. Click "Next" to continue. This will take you to the Ready to Repair page.
    • 5 Click "Repair" and SQL server disc will run its repair function. The repair progress bar will show the completion level of the repair. Once the repair function is complete, click "Finish" to exit the repair program. Reboot the server machine to complete the repair."

    This is very bad. You may have a disk with no space left, or somehow, SQL Server has lost it's handle on the file. It could also be a Virus Scan is grabbing the file, and not letting SQL Server get the file back (SQL Server needs exclusive access to the data files for what should be obvious reasons). Find the root cause by looking in the errorlog of the instance in question.

    Sql

    Data from corrupt mdf file can be recovered by following methods:

    Repair MDF file with DBCC CHECKDB: Microsoft offers a command that is known as DBCC CHECKDB, when you run this then it try to detect & fix all the possible error message. If it fails to fix error message then it suggest repair clause. Re-run the command with suggest repair clause. Your problem might be solved. But, you may loss some amount of data after this.
