Microsoft SQL Server is a data platform leader that is used to manage data comprehensively and for an integrated analysis that enables every organization to easily manage their mission-critical information to run complex business applications with confidence.
RAID: RAID (redundant array of disks) Server is considered to be one of the most trusted storage mediums. Most organizations use RAID for storing their significant SQL Server databases.
Evident Corruption is SQL: Even when there is an availability of intrinsically existing data defense in SQL Server system and RAID, still SQL corruption cannot be ruled out and the need for MS SQL recovery cannot be completely avoided. Apparently, such incidences are common and still evident as you know that even the best configured systems fail when the unavoidable and inescapable corruption issue strikes.
Problems Due to Corruption: When corruption issue strikes, you may lose all of your crucial data saved in SQL Server MDF files, but sometimes it is possible that you may get some traces of data, which can help you recreate the database. You restore the database from an updated backup.
Database Inconsistency: Unfortunately, when you restore data from backups that are created through a database running on DTP SmartRAID V controllers, you can encounter the following error message:
“Msg 3270, Level 0, Sev 16.
An internal consistency error occurred. Contact Technical Support for assistance.”
Invalid File Header: Now, when you try to detach the database using sp_detach_db stored procedure and attach it again using sp_attach_db stored procedure, you can see the flowing error message on your screen:
“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, restoration process will stop and you will not be able to access your database.
Major Cause behind This Trouble: As clearly visible in the above error messages, such problem can occur either due to inconsistency in the database or due to invalid file header. In both the cases, database gets damaged and prevents even a single bit of data to be retrieved from it. In such situation, you need MDF file recovery solutions. MS SQL recovery can be easily and efficiently carried out using professional help in the form of third-party SQL data restore software.
MS SQL Database Repair: SQL corruption creates the urgent need for SQL database retrieval which should only be done using a reliable and highly convenient tool. This will bring you in a dilemma where you might think, “How to perform SQL recovery easily and accurately?” There are easy to use tools, which allow quick and trouble-free SQL Express database repair in most cases of MDF corruption. One such tool is SysTools SQL Recovery software. This is a useful tool that even helps you to carry put SQL suspect database repair and also SQL Server backup recovery. Also the recovery process, you will be able to open MS SQL database without encountering any error message.

How to Read MDF Files after Failed MDF Restoration Due To File Version Conflict?
You cannot restore data from a backup created on SQL Server file version different from the one on which you are attempting to restore. When you do this, you encounter the following error message, after which the restoration process will stop:
“Server: Msg 3168, Level 16, State 1, Line 1
The backup of the system database on device d:\temp\master.bak cannot be restored because it was created by a different version of the server (134217904) than this server (134217920).
Server: Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE
is terminating abnormally.”
Probable Reason behind This Problem – File Version Conflict: This problem mainly occurs when the system database schema is changed, which leads to the file system conflict of SQL Server causing inconsistencies. This happens due to file version mismatch. After you encounter the above error message, you will not be able to restore your corrupted database from backup. For database administrators and organizations, this can really put out their business.
Possible Workaround for this Problem: The alternative method to avoid the above mentioned problem is to install the same SQL Server file version as in the backup system. This will avoid the file version mismatch and file system conflict. However, upgrading or degrading SQL file version can even make situations worse for you. Your MDF file can be damaged further and in the worst situation, it can even become completely irreparable. Therefore, third party MDF file repair tools are always recommended.
Possible Solution for this Problem: The best possible solution to deal with the above mentioned problem is MS SQL recovery using third-party MDF file repair tool that can help you to repair corrupt MDF file after which you can open MS SQL database easily. A sought after product that can answer your alarming question – “How to read MDF files?” in perhaps the best possible way is SysTools SQL Recovery software.

Resolve SQL Corruption Caused Due to Transaction Log Files Removal Interrupting Database Mirroring
Database Mirroring: In SQL Server 2008, you can use the feature of database mirroring between two databases. It can help in the data loss situations where a database damages for some reason; you can back up your database from the mirror database.
Transaction Log Files Removed Accidentally: If by chance, you remove the transaction log files; the database mirroring session can interrupt. This causes the Principal Server to fail and you will not be able to restore the data from mirror server. This can cause corruption damaging the database.
A Possible Scenario: Consider a practical scenario where you are using SQL Server 2008 SP1 (Service Pack 1) or MS SQL Server 2008. You configure mirroring between 2 databases.
Transaction Log Files Removed – Errors Encountered: You run ALTER DATABASE command with REMOVE FILE clause for removing the transaction log files on the main SQL Server database. This can abort database mirroring session, which you cannot resume. You can also receive the following message:
“Location:" logmgr. cpp ": 3350
Expression: headLFCB-> lfcb_startOffset GetSize () * (ULONGLONG) PAGESIZE”
After that, you get the below error message in SQL Server event log logged:
“spid23s A system has failed. Check the SQL Server error log for more details. Typically, an assertion is by a software bug or data corruption. To check for any damage to the database, DBCC CHECKDB. If you send causes agreed to dumps to Microsoft during setup, a mini dump will be sent to Microsoft. An update is available from Microsoft in the latest service pack or in a QFE from Technical Support.”
Cause behind SQL MDF Corruption: The main cause behind problem can be the incorrect log on mirror-space tracking database or due to SQL database MDF file corruption.
