When SQL Server database files are damaged, avoid making changes to the original MDF or NDF files because further modifications can affect the available data. Instead, create a copy of the affected files and use a database recovery method to examine their contents. A recovery solution can scan the damaged files, identify recoverable database objects, and provide a preview before the recovered information is saved.

One option for handling damaged SQL Server files is Aryson SQL Database Recovery Software. It supports recovery of corrupted MDF and NDF files and can retrieve tables, views, indexes, triggers, functions, and stored procedures. The software provides Standard and Advanced Recovery modes, allowing users to scan the database files and preview the recovered objects before exporting them.

If your goal is to restore SQL Server Database  with damaged files, load the affected MDF or NDF file into the recovery software and run the appropriate recovery mode. After checking the preview, the recovered database can be saved to a new or existing SQL Server database or exported as SQL Server-compatible scripts containing schema and data. This approach can help recover usable database contents when the original files are damaged.
