Hi @VŨ DUY
You could repair SQL MDF and NDF file by this TSQL command:
EXEC sp_resetstatus [YourDatabase]; ALTER DATABASE [YourDatabase] SET EMERGENCY DBCC checkdb([YourDatabase]) ALTER DATABASE [YourDatabase] SET SINGLE_USER WITH ROLLBACK IMMEDIATE DBCC CheckDB ([YourDatabase], REPAIR_ALLOW_DATA_LOSS) ALTER DATABASE [YourDatabase] SET MULTI_USER
Please refer to this article for more details or other methods: Repair Crashed SQL Server.
