After I downloaded the file I tried to run this SQL statement:

CREATE DATABASE AdventureWorksDW2012 ON (FILENAME = 'E:\MSSQL11.SQL02\MSSQL\DATA\AdventureWorksDW2012_Data.mdf') FOR ATTACH_REBUILD_LOG;

I get the following error:

Msg 5172, Level 16, State 15, Line 1 

The header for file 'E:\MSSQL11.SQL02\MSSQL\DATA\AdventureWorksDW2012_Data.mdf' is not a valid database file header. The FILE SIZE property is incorrect.

I am new to this site and I opened an issue for this problem. Was that an error on my part?

Dan
