In my last post, I demonstrated how to mount a database with missing NDF files. In the end, we still have issues removing tables created over missing files, the files are taken offline. Be cautious of taking files offline since there is no (official) way to bring it back online. In either situation, you will need to modify/correct SQL Server metadata. This is allowed in SQL Server 2000 with “Allow ad hoc update” option turned on. However, it’s deprecated in SQL Server 2005 and removed in SQL Server 2008 and upper versions.
