For brief information on Disk Utility (Applications -> Utilities):

David,

To enable Finder to display 'hidden' files and folders, open a  
Terminal and paste in:

defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder


Finder will restart after the last command.

Note that doing this will also display files that begin with a '.'  
which are normally hidden, but which can be beneficial to show. Files  
such as .RData and configuration files such as .emacs will now be  
visible. However you will also see files such as .DS_Store in each  
folder and on the Desktop, which is a system file for Finder. It will  
also show these hidden files and folders files when installing new  
applications, which risks confusing folks.

To re-enable the default Finder behavior, paste this in to a Terminal:

defaults write com.apple.finder AppleShowAllFiles FALSE
killall Finder


HTH,
