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.

The tempdb database is a global resource of MS SQL Server, which is available for all users that are connected to instance of Microsoft SQL Server. This database stores temporary user objects, internal objects that are designed by SQL Server Database Engine, row versions that are resulted by data alteration transactions and row version that are resulted by data alteration transactions for features. In some cases, when you try to repair a damaged tempdb database using CHECKDB command, SQL Server database corruption may occur. This behavior renders all of your mission-critical data inaccessible and thus you need to opt for SQL Recovery solutions to retrieve data.
In a practical scenario, when any of the database user raise attentions during process of SQL Server, you might come across any of the below error message:
Server: Msg 8946, Level 16, State 1, Line 1
Table Corrupt: Allocation page (1:253) has invalid IAM_PAGE page header values. Type is 1. Check type, object ID and page ID on the page.
Or
Server: Msg 8906, Level 16, State 1, Line 1
Page (1:253) in database ID 2 is allocated in the SGAM (1:3) and PFS (1:1), but was not allocated in any IAM. PFS flags ‘IAM_PG MIXED_EXT ALLOCATED 0_PCT_FULL’.
Attains are raised by SQL Server clients while server is executing or performing commands, necessitating non-logged allocations in tempdb file like worktables for the cursors.
Cause
As stated in above error, this issue is caused by corruption to the SQL Server database table. When the database table gets damaged, an invalid value is written in header of IAM_PAGE page of table and the operating system could not identify table and gives you error messages.
Corruption to the SQL Server database table might occur due a number of reasons ranging from improper system shutdown to virus infection. When database corruption occurs, it neither accessed nor repaired through CHECKDB utility.
In such situations, you need to repair and restore the database using third-party SQL Repair applications to retrieve inaccessible or damaged data. The SQL Recovery tool perform systematic scan of affected database to ensure absolute recovery.
The software are quite easy to use as they have self-descriptive and interactive graphical user interface. SQL Repair is completely safe with these programs as they have read-only and non-destructive conduct.

Microsoft SQL Server is the most popular and advanced Relational Database Management System (RDBMS), which is developed and marketed by Microsoft Corporation. The SQL Server enables you to use the T-SQL (Transaction Structured Query Language) to carrying out database transactions. T-SQL can be created to effectively manage SQL Server and to prevent unauthorized access of the database. SQL Server stores all of the data in MDF (Master Database File) in the form of several different tables. In some situations, these tables might get damaged and thus become inaccessible. This behavior of MS SQL Server cause critical data loss situations and require SQL Recovery to be sorted out.
Due to the advanced features, which SQL Server offers, there are several organizations who use it for effective management of their databases. But your decision of use the MS SQL Server might prove wrong when you can not get access of your mission critical data.

A SQL database provides solid back end database support to various websites and front end applications. We can easily and efficiently process heavy volumes of database operations using SQL Server. The database corruption is a common problem witnessed by many database professionals which pertains to error in one or more of SQL Server database components/objects like tables, views.
DBCC CHECKDB command enables you to check the physical and logical integrity of all the database components in SQL database. This in-built SQL Server command also reports about the database corruption. To effectively and systematically resolve the SQL database corruption, you need to use efficient SQL Recovery software.
When a user runs a DBCC CHECKDB command on your SQL Server database, he encounters the following error message:
“Server: Msg 2537, Level 16, State 1, Line 1 Table error: Object ID 587149137, index ID 0, page (1:1325), row 0. Record check (Valid Sql_variant) failed. Values are 1 and 0.”
The main reason for the above error message is corruption in the SQL database of MDF file. The user encounters this error message when all the below conditions are true:
• The data originates in another column that is of sql_variant data type and at some point data is sent to other system by the SQL Server.
• The sql_variant column contains numeric values.
• SQL server loads the data into a column that is of sql_variant data type.
Once the above error message appears on the screen, the data stored in the SQL database becomes inaccessible. To resolve the above error message and perform complete sql database recovery, the user needs to use a third party application named SQL Recovery software.

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.
