There are some situations where your MS SQL Server might crash due to hardware problems. In these cases, you need to recover your database, which is possible with the help of transaction log files.
It is very useful method of restoring the MDF file of SQL Server, but sometimes when you attempt to attach the MDF file after recovery, you may fail to do it and might come across with the following error message:
“Error 5171: path……\.mdf is not a primary database file.”
In such situations, most of the database administrators recommend to attach a single file. But here it also doesn’t work. When you use sp_attach_single_db Stored Procedures, you may get the following error message:
“Server: Msg 5172, Level 16, State 15, Line 1
The header for file path……\.mdf is not a valid database file header. The PageAudit property is incorrect.”
After these error messages, none of data from SQL Server remains accessible and it can lead to the nightmare of data loss.
