There was no log file, just mdf. I don’t know why but it is not very easy to get this database online. After some digging in internet I found solution. I suggest you to read and try out example by Paul S. Randal <a href="http://sqlskills.com/blogs/paul/post/TechEd-Demo-Creating-detaching-re-attaching-and-fixing-a-suspect-database.aspx" style="box-sizing:border-box; background:transparent; color:#428bca; text-decoration:none">TechEd Demo: Creating, detaching, re-attaching, and fixing a suspect database</a>. I also suggest you to bookmark this posting, you never know…. I found simplest solution from stackoverflow: <a href="http://stackoverflow.com/questions/773059/how-to-recover-database-from-mdf-in-sql-server-2005" style="box-sizing:border-box; background:transparent; color:#428bca; text-decoration:none">How to recover database from MDF in SQL Server 2005?</a> It works also for SQL Server 2008. <ol> <li>Create database with same name as MDF file you have.</li> <li>Stop SQL Server and swap MDF files. Make sure you also keep new database you just created.</li> <li>Start SQL Server. Database will be now in suspect state because log file is not correct.</li> <li>Run the following script:   USE [master] GO ALTER DATABASE [MyDatabase] SET EMERGENCY GO ALTER DATABASE [MyDatabase] SET SINGLE_USER GO DBCC CHECKDB ([MyDatabase], REPAIR_ALLOW_DATA_LOSS) GO ALTER DATABASE [MyDatabase] SET MULTI_USER GO ALTER DATABASE [MyDatabase] SET ONLINE GO</li> </ol> When I ran this script I got the following output.     <hr /> Msg 5173, Level 16, State 1, Line 1 One or more files do not match the primary file of the database. If you are attempting to attach a database, retry the operation with the correct files.  If this is an existing database, the file may be corrupted and should be restored from a backup. Log file 'c:\Program Files\Microsoft SQL Server\MSSQL10.SQLEXPRESS2008\MSSQL\DATA\MyDatabase_log.ldf' does not match the primary file.  It may be from a different database or the log may have been rebuilt previously. Warning: The log for database 'MyDatabase' has been rebuilt. Transactional consistency has been lost. The RESTORE chain was broken, and the server no longer has context on the previous log files, so you will need to know what they were. You should run DBCC CHECKDB to validate physical consistency. The database has been put in dbo-only mode. When you are ready to make the database available for use, you will need to reset database options and delete any extra log files.
