I'm not sure if i am posting this in the right place, but i really need help, i've recently updated my laptop to os x lion and in doing so it keeps deleting folders such as music folders, application folder and iPhoto folders, is there anyway possible in retrieving these items as there is a lot to replace. I'm not really a whiz at macs and i'm not entirely sure where to start looking. Please if anyone has any know how let me know.
