Author: SQL database corruption can occur due to SQL Server malfunctioning, virus infection, improper system shutdown, hardware failure and many more. Once the MS SQL database gets corrupted, the SQL database become inaccessible. In such situations, use you backup, if there is no backup, the user needs to repair mdf file by using advanced MDF Repair application. Consider a practical scenario, where a user is working on SQL Server 2005 and creating a report. While doing so, the Windows restarts due to power failure. When user restart the system, the SQL database becomes inaccessible. When the user tries to attach the MDF manually, he encounters the below error message:
“An exception occurred while executing a Transact-SQL statement or batch. _db.mdf is not a primary database file. (Microsoft SQL Server, Error: 5171).” Or
“C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\MYDATABASE.mdf is not a primary database file. (Microsoft SQL Server, Error: 5171)” In such circumstances, the database administrators recommend to attach a single file. However, when the user uses sp_attach_single_db Stored Procedures, the user encounters the following error message:
“Server: Msg 5172, Level 16, State 15, Line 1 The header for file path……\.mdf is not a valid database file header. The PageAudit property is incorrect.” Cause:
The above error message encounters due to MDF file corruption. The above issue occurs when the MDF file header gets corrupted or some invalid information is inserted in the header file. All these situations result, inaccessibility of the SQL database. To ensure accessibility of the SQL database, the user needs to recover it by using the latest backup. But sometime user has not created any backup of its database or mdf file, then he needs to perform MDF repair. To do so, user needs to use efficient and effective MDF repair application. Such mdf file repair applications incorporate advanced and powerful scanning algorithms to repair the corrupted MDF file. The mdf recovery software perform systematic scan of corrupted MDF files, repair and restore them in their original format without altering any information.

RAID servers are considered as the most trusted and reliable storage medium. But sometimes, they may also lose all the hard drives, which include your important data, backups and other information.
Most of the organizations use RAID for storing their important SQL Server databases. When they fail, generally you may lose all of your data, but sometimes you may get some traces of data and can recreate the database.
In such situations, you can save your database by restoring the database from your backup. But unfortunately, when you try to restore backups, which were made through MS SQL Server for a database, which is running on DTP SmartRAID V controllers, you may receive the following error message:
“Msg 3270, Level 0, Sev 16.
An internal consistency error occurred. Contact Technical Support for assistance.”
In this case, when you attempt to detach the database using sp_detach_db stored procedure and then attempt to attach the database again with the help of sp_attach_db stored procedure, you may get the flowing error message:
“Server: Msg 5172, Level 16, State 15, Line 1.
The header for file ‘d:\pubs.mdf’ is not a valid database file header. The PageAudit property is incorrect.”
After this error message, the restoration process gets halted and you can not access anything from your SQL Server database.
Grounds of the trouble
As stated in the above error messages, this problem is either due to inconsistent state of the database or due to invalid header entry for the database. In both of these cases, the database may get damaged and thus even a single bit of data can not be retrieved from it.
In such disastrous situations, you need to perform SQL recovery to repair the damaged database and retrieve all of your data from it. SQL recovery can be carried out using the MDF recovery software.
