Let me get this straight. You filed a bankruptcy and your upset because it HASN'T been reported?
If you filed in 2005 don't worry, it will show up sooner or later. I use to work collections at a major bank and I know a thing or two about these things.
What you want to concern yourself on your CBR is any sign of identity theft. If it's a question of accounts that were closed and such you can contact the companies on line and have them investigate as someone else mentioned.
In any case once it does appear on your CBR it's there for a full 10 years. That doesn't mean you can't get credit, it just means you'll pay higher interest. Some banks may still turn you down, mine would.
Honestly I wouldn't worry too much about the CBR at this point. Give it another year then take a look at it.
