Recover Master File from SQL Server database by SQL Recovery Software

Structured query language (SQL) is a database computer language designed for managing data in RDBMs developed by Microsoft corporation. It has two primary query languages, ANSISQL and T-SQL. It offers the facility to access SQL Server database from anywhere, be it from your desktop or data center. It also provides combined services to search, query, report synchronize and analyze the database records. Sometimes it may happen that the SQL Server is unable to run. It may possible that the master database of SQL Server has gone damaged. This can be possible because of several reasons such as human errors, virus infections, power outages while SQL Server was open. In that case, you should replace the damaged database with its clean and backup. However, if the backup is not clean and updated then you should use an advanced sql recovery software to recover SQL database. Consider a case wherein you have Microsot SQL Server installed on your machine. When you try to log on to the SQL Server, you are unable to do and an error message is appered, that is: "Cannot recover the master database. SQL Server is unable to run. Restore master from a full backup, repair it, or rebuild it. For more information about how to rebuild the master database, see SQL Server Books Online." Cause:

The possible cause for the above mentioned error message is that the SQL Server database is unable to start the master database. If the tempdb or master database can not be mounted, SQL Server can not run. It is possible that the master database of SQL Server has gone damaged because of various above mentioned reasons. Resolution:

To solve the above issue, you should first of all, check there is a clean and updated backup of the master database. If yes, then you should replace updated backup with the damaged master database. However, if the database is not clean and updated then you should use a SQL repair tool to perform sql recovery of the damaged master database.

How to recover MDF file when you encounter Error 8910 in MS SQL Server 2000

Are you getting error messages repeatedly while working on a particular database in MS SQL Server 2000? If yes, then you should check the exact cause of these messages as there may be chances of database corruption. The database corruption can happen due to various reasons including virus infections, malfunctioning of the hardware components, abrupt or unplanned system shutdown while the database is open, etc, which could even make the database inaccessibile. In such cases, you should look for MDF file recovery using appropriate corrective methods, failing which you must use a third-party MS SQL Server recovery software to do the needful.

Let us consider a situation in which you are getting the following error message while working on an MS SQL Server 2000 database:

“Page P_ID in database ID DB_ID is allocated to both object ID O_ID1, index ID I_ID1, and object ID O_ID2, index ID I_ID2.”

Cause:

The most prominent reason behind this error is that the index definitions in the IAM pages have damaged.

Resolution:

To perform MDF recovery of the damaged SQL database, you should perform either of the following methods, ideally in the given sequence:

• Address hardware related issues: It may be possible that the error is occurring due to hardware corruption, which can be resolved using the following measures:

  • Fixing the issues that appear after running hardware diagnostics.

  • Swapping the hardware components to isolate the exact reason and fixing it.

  • Checking the Windows application log and the SQL Server error log to find out whether the error has occurred due to hardware malfunctioning.

  • Checking if the hard disk has write-caching enabled. If yes, then contact the hardware vendor to replace the hard disk.

• Restore from database: You should check the state of the database backup. If it is updated and clean, then you should restore the database with its backup.

• Run DBCC CHECKDB: If the backup is not clean, then you should run the DBCC CHECKDB tool with the suggested repair clause to recover MDF file.

If these aforementioned methods are unable to address the situation, then you would need to take the services of a third-party master database file recoverysoftware. With the use of read-only recovery mechanisms, these SQL recoverytools ensure that no type of data is lost or damaged during the recovery.
