SQL Database Recovery to Handle Database Page Corruption

Microsoft SQL Server uses numerous objects to effectively manage your valuable data within the database and a database page is one among them. MDF (Master Database File) or MS SQL Server database is internally divided into pages. Every database page includes one 96-byte header, which contains page related information such as page type, page number, free space, and page ID. When metadata structure corruption takes place, it usually fails to read the pages and cause data loss. Data loss is one of the most critical situations that a computer user may face. It puts you in need of comprehensive SQL Recovery solutions.

SQL Server database pages are very much prone to corruption and may leave your data unusable in a number of cases. The pages corruption might be the outcome of improper editing of MDF file. As a practical example of the problem, you may come across the subsequent error message while attempting to mount an SQL Server database:

“Could not read and latch page P_ID with latch type TYPE. OPERATION failed.”

You get this error every time you try to mount your database. This behavior makes your significant data completely inaccessible. In such critical situations, you are required to find out the root cause of this issue and then fix it using SQL database recovery solutions.

Reason:

The most frequent causes of this problem with Microsoft SQL Server database corruption can be any of the following ones:

• The page that you are trying to access is in the repairing state.
• SQL Server is performing an intermediate operation on particular page.
• The page is read as the part of every checks of significant SQL database system tables.
• The page is too damaged to be recognized by MS SQL Server.

You may face this issue due to either logical or physical MDF file corruption.

Solution:

Use any of the following MDF recovery solutions to work around this issue-

• Detect and fix consistency issues using DBCC CHECKDB command. It is an inbuilt SQL repair tool of SQL Server.
• Restore database from the latest backup.
• When both the above solutions fail to work, go for third-party SQL database recovery software.

SQL Recovery applications are helpful to scan whole database and recover SQL database in all corruption scenarios. They help you recover all database objects, including Tables, reports, forms, Macros, queries, constraints, and more.
