The file header is the bank of relevant information, whose absence or corruption can make the file inaccessible. For even the MDF file, which is the prime repository of data for SQL Server, the header corruption can occur with regard of many reasons ranging from virus attack to application faults. The situation is weird and hard to digest for the database administrator.
However, in this case, you may get error messages like the following:
“The file header is corrupted and is not a valid database file”
Or
“Msg 5172, Level 16, State 15, Line 1
The header for file ‘D:\DbName\DbFileName.mdf’ is not a valid database file header. The <attribute> property is incorrect.”
Most of the reports say that these error messages occur when the user tries to attach the MDF file to SQL Server.
The file header of MDF is corrupt. So you can try out attaching the file by some other methods, instead trying it directly. Try to create the similar database and then swap the corrupt files after shutting down the SQL service.
