Missing Favorites Bar for finder

Question

After getting an error from itunes(error 54). I had to repair disk permissions. Now the section that has airdrop, applications, desktop, music, pictures...etc is gone. I cant add it from finder preferences either. All I can add is stuff from devices, and shared, but not favorites. I tried to delete the finder plist, but i cant find it 

Answer 1

Back up all data.
Triple-click the line below to select it:
~/Library/Preferences/com.apple.sidebarlists.plist
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item selected. Quit the application if it's running. Move the selected item to the Desktop, leaving the window open. Relaunch the application and test. If there's no change, quit again and put the item you moved back where it was, overwriting the one that may have been created in its place. Otherwise, delete the item you moved.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
