I just updated my Mac with OS X Lion. After playing a while, I realise I can't find Macintosh HD. It no longer at left-side bar in Finder. I need it.
So I came out with a solution as below:
- Right click on Application and click Open Enclosing Folder. It will open Macintosh HD folder in new window.
- Drag the top center icon, disc, to the left-side bar in Finder under Favorites.
Now, I have Macintosh HD folder as favorited folder in Finder.

Another solution is open Finder Preferences, select / check Hard disks on Sidebar tab under Devices section.
