Resolving Problems in MDF Due To Database Inconsistency and Invalid File Header

Tweet

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.
