Settings (and hiding things)

Inside my 'Computer' icon I can see all my hard drive partitions, including the Windows ones (although the Windows partitions don't get mounted). That's fine because I don't want to mount them. In fact, I'd prefer not to even see them. I know this is possible with Linux but it seems to be subtlely different for different distros. How do I configure the Computer icon so that it doesn't list my Windows paritions? Also, does 64studio have any equivalent to Ubuntu's 'gconf-editor'? It's quite a neat little utility that allows you to customize lots of system settings - including what things are visible (or not visible) in various locations.
