How To Control Error Log File In SQL Server 2005 Express?

I attached a SQL database called Cars, using the following code:




Code Block

IF NOT EXISTS(
SELECT *
FROM sys.databases
WHERE name = N'Cars'
)
CREATE DATABASE Cars
ON PRIMARY (FILENAME = 'C:DataServer FilesCars.mdf')
FOR ATTACH
GO






I then detached the database using:




Code Block

EXEC sp_detach_db @dbname = 'Cars'
,@skipchecks = 'true'
,@KeepFulltextIndexFile = 'true'
GO





I then copied the .mdf and .ldf to another folder, using Windows Explorer.

I then attached the database using the new folder name in my code.:




Code Block

IF NOT EXISTS(
SELECT *
FROM sys.databases
WHERE name = N'Cars'
)
CREATE DATABASE Cars
ON PRIMARY (FILENAME = 'C:DataNew FolderCars.mdf')
FOR ATTACH
GO







Now when I go to update my table, I see that I am hitting the .mdf in the new folder.

And, when I do my table updates, I see that I am hitting the .ldf in the old folder.

Two questions:
1. What did I do wrong, that updates are hitting the new .mdf, but the old .ldf?
2. How do I control what .ldf SQL Express uses?

I see references to 'SQL Server Agent' in the help pages, but do not see 'SQL Server Agent' within the application.

I see the reference to the old folder path, within the 'Database Properties Files page', but no possibity to edit the value.
