I could be wrong but I read somewhere that just adding links to the disavow is not enough - you actually have to make an effort to have those links deleted and submit some kind of report on your action,
I read the same thing, and it was from a Google source, too. I think it was Matt Cutts, but he has talked a lot about Disavow Lonks and I'm having trouble finding that exact link.
Not only does Google want to see the effort to delete those links, but they also want a Reconsideration Request after the effort, too. And even then, they often tell you to make more of an effort, and even when they say OK, many members here report that their rankings do not come back. Some have had improvement but that seems to be a lower percentage.
Here are a couple references that might help:
