Hi there, I've also got the error "Server: Msg 8985, Level 16, State 1, Line 1. Could not locate file 'MyDb_Log' in sysfiles" when trying to shrink one of my databases's log files. I think I know the cause of the problem. When you de-attach a database, rename the database file and then re-attach the database then this error message will apear. The solution, delete that current database and create a new one but NEVER EVER rename the file...
