For people without an external disk sitting around, note that you can  
also do this via a mountable disk image. Here's an example to create  
a case-sensitive HFS+ image:

hdiutil create -size 10m -fs "Case-sensitive HFS+" -volname MyVolume  

For more information, try "hdiutil create" or "man hdiutil".
