I created a database in SQL Server 2008. I detached the database and I copied the `.mdf` over to the server, which is running SQL Server Enterprise Manager (SQL Server 2000). 

When I try to attach the MDF I get...

> 
> *Microsoft SQL-DMO (ODBC SQL State: HY000) Error 602: Could not find
>  row in sysindexes for database ID 13, object ID 1, index ID 1. Run
>  DBCC CHECKTABLE on sysindexes.*
> 
> 
> 

What does this mean? Is this because the db was created in a newer version?
