HI Deepika

You cannot run tar compaction unless last good segment is restored. Follow the instructions provided by Tiago here - http://help-forums.adobe.com/content/adobeforums/en/experience-manager-forum/adobe-experience-manage...

Reason for this corruption could be anything like you may have not disabled online compaction or  CQ process was killed abruptly and so on.

Hope this helps.

Regards
