Let’s take a look at the challenges faced by the users to understand the issue in a better way and provide efficient solutions to resolve the error. 

• The major issue the users get with this error is the inability to access the impacted database.
• Data unavailability, partial or complete, of the secondary database files. 
• This might lead to SQL Database downtime if not resolved accurately.

How to Resolve the SQL Server Error 5125?

There are various solutions to resolve the error depending on the possible causes of the error. We will take a look at these methods one by one to understand how they will help in resolving the error. Beginning with the first method. 

Method-1 Check the System for Any Hardware Issues

To check if there are any issues with the disk, use the chkdsk command. With the help of this command, one can detect and repair if there are any issues with the disk. 

The syntax for doing the same is chkdsk X: /f.

(here change the X: with the drive you wish to check)

Along with checking the disk for any minor issues, it is also important to monitor the hardware for performance issues or high resource usage of the CPU. 

Keeping track of these operations and drives can help you understand the major cause of the occurrence of the SQL Server Error 5125.

Advanced Solution To Fix Issues in SQL Server

In case of this SQL Server Error, there is a high possibility that there might be issues in the SQL Server Database. Resolving the error might put you in a certain situation of data loss from the SQL Server database. So to check for the issues more securely, you can choose an advanced solution. The solution we trust and recommend is the SQL Server Database Recovery Tool. With the help of this tool, you can repair the database without compromising the safety of the data within.

Let's quickly understand how this solution fixes the SQL Server Error 5125.

Step 1: Launch the Software and click on Open to load the files.

Step 2: Choose the NDF files using the provided options.

Step 3: The NDF file scanning will be initiated. Preview the files afterward.

Step 4: After preview, to export the database files, add all the required credentials.

Step 5: Choose the With Schema and data option and click on Export button.

Method-4 Use Emergency Mode to Resolve the Error

This method is the last resort for resolving this SQL Server error. The user has to run the following queries to resolve the issue with the help of emergency mode.

Phase 1: The first phase of this method includes checking the error logs first to detect any possible errors. To check the error logs in SQL, use the following command:

DBCC ERROR LOG;

GO

The command will perform the given operations:

• It will check the error log for any issues in it.
• Will try to repair the log (if needed).
• Might result in deleting all the data in the error log.

Phase 2: The second phase of the method involves using the DBCC CHECKDB command to repair the database, in case the issue is unresolved after the first phase. 

The following command will help you to detect and repair any issues in the SQL Database.

DBCC CHECKDB ([DBNAME], REPAIR_ALLOW_DATA_LOSS);

This command is equally risky as it might resolve the SQL Server Error 5125, but also result in the loss of the complete data from the database. This method is supposed to be used as a last resort only.
