HI Mani,
We will start looking into a very different direction. This was just to identify whether reposcan is working as expected provided by berend. 
@Randy : Comparing the two we can check for the availaability of the report, and understand that the metadata and the physical file is in sync or not.,
If the metadata and physical file are not in sync, it means reposcan has actually identified there is a possible corruption occuring at CMS Db level.
