Rebuilding directories

> My harddrive died last week and I am able to use it as
> long as I don't boot off of it. All the files looked
> complete and at first I couldn't get into the various
> document and settings files because I didn't have
> priveleges....
> Then I read here how to take ownership, unfortunately by
> the time I was ready to take ownership when I booted up
> the two disks, my new and my old, the document and
> settings folder had dissapeared. I know the files are
> still there because when I took ownership of the entire
> drive it listed many of the files which are in the
> document and settings folders. Before I scrap this disk,
> I would like to retrieve all of those files or as many as
> are still good... (especially my .pst file).
> So, then the question is any reccomendations on how to
> either rebuild the directories, undelete these files
> etc.? I just want to get off this difficult disk...
