Bitlocker key problem: Brute Force or recovering the key file?

[arashg]

Hello,
I have full disk encryption with BitLocker.
The key file for windows partition was on my USB disk, other drives were protected by password and also they're set to automatically unlock.
Yesterday, I found my USB disk corrupted. When I performed chkdsk on it, everything went fine except than my key and recovery key files were deleted!
I can remember the password and I had managed to unlock my drives by 'manage-bde -unlcok -pw' command.

Can anyone suggest anyway for recovering my windows partition? Is there any brute force tool or something similar that can exploit the informations I have, like recovery key ID?

I've tried to recover the USB disk by using a number of softwares, incluing Active Undelete which seems to be the best one, but it was useless. It can find the files but not their data. Can you suggest anything for recovering the key or recovery key file?
Is there any chance that I can somehow find the files on the computer that I performed chkdsk on it?

Please help, this is super important.

Thanks in advance.
