Tips to resolve “The system cannot...” Error message

Corruption in MS SQL database can occur after various logical corruption scenarios like improper system shutdown, metadata corruption, PFS page corruption, system table damage, operating system malfunction, and virus attacks. In most database corruption scenarios, the database becomes unmountable making the records inaccessible. For easy accessibility of all the database records, an ideal way is to restore the records from an updated and valid database backup. But if in case, the database backup is not available or backup itself has been corrupted, then you will need to use advanced SQL Repair tool to repair the corrupted MS SQL database.

As a practical instance, you encounter an power outage while you were making some changes in your database. The system shut down unexpectedly and the database also closed improperly. However, when you attempt to mount the database after restarting your system, you encounter the below error message:

“The system cannot self repair this error.”

You receive the same error message each time you attempt to mount your database. The records saved in the database become inaccessible after you encounter the above error message.


The fundamental reason for the occurrence of the above error message is the corruption of MS SQL database.


To resolve the above error message and access the records saved in the database, you will need to run DBCC CHECKDB command with REPAIR_ALLOW_DATA_LOSS option. In most cases, the database gets repaired using this command and you can easily access your records. However, using the command with repair option may result in loss of data stored in your database. To avoid any possibility of data loss, a safe and better way is to use third party SQL Recovery tools.

Such SQL Database Repair tools use powerful scanning algorithms to comprehensively scan and repair the corrupted MS SQL database. These MDF repair applications come with highly interactive user-documentation that makes them easy to understand to both technical and non-technical users. Their non-destructive nature makes the database repair completely safe and risk-free.
