From Beta 3 Current to Beta 3: mount: incorrect super block

[sam]

Hi,

I downgraded my system from FBSD 53Beta Current (a week ago) to 53Beta 3 
(the one from freebsd ftp site) by reinstalling the whole system without 
wipeing out the entire file systems. I m not sure how much they are 
likely the same. There is a customized partition is not able to be 
mounted after the installation. The error is:

mount: /dev/ad0s2a on /bdata: incorrect super block

Is there any way I can mount this partition?

Thanks
Sam
