Are you saying it is the last block precisely that is zeroed out? And that is 100% of the block? Given the config you've described, I think only Oracle or VxVM could be to blame for that. Since the DMX is virtualized by VxVM and the problem happened on 60-70 datafiles, I think the odds are too astronomical that the DMX did it since those magic last blocks are strewn all about.
