Disable DB without deleting data

[Kirk Hoganson]

I need to find an easy way to make a database unavailable without 
deleting the data, so that it could be easily and quickly restored if 
necessary, without impacting the availability of the other databases.  
Something like moving the databases subdirectory to a different 
directory, or the "detach" feature in MSSQL.  The MySQL server (5.0.45) 
is running on a Windows server, and is using the InnoDB storage engine.

Thank you for any suggestions.
