When dealing with corrupt SQL Server database files, I would avoid jumping directly to REPAIR_ALLOW_DATA_LOSS, especially when the database contains critical business data. The first step should be to identify the corruption using DBCC CHECKDB and determine whether a clean backup or page-level recovery is available.
If backups are unavailable or the MDF/NDF files are severely damaged and the database cannot be attached, a dedicated SQL recovery utility can be more practical. I have used SysTools SQL Recovery for this type of situation and found it useful for scanning corrupted MDF/NDF files, previewing recoverable database objects, and exporting the recovered data to a live SQL Server database.
The main advantage is that recovery can be attempted without repeatedly modifying the original database file. I would always work on a copy of the damaged MDF/NDF and verify the recovered database thoroughly after export.
For minor corruption, SQL Server's native recovery and a good backup should remain the preferred approach. For severe file-level corruption where those options are no longer sufficient, this is a practical recovery option worth considering.
