Disabled iPad -I passcode can I try again

what if someone else disabled my ipad, but I know my passcode? Is there a way to have another chance to unlock it? I come to my ipad one day and it says "ipad disabeld connect to itunes"... but I know my passcode... I never had an issue entering it.

I want to do this because I have a LOT on my ipad and its not backed up completely...  really ****** I dunno what happened...
