Hi Chad,

When Oracle creates a data file it zeros each block.  I think this policy is so 
that sparse or "holey" files are not created and there are no disk spaces 
suprises later on.

Regards

Doug

Are any of the recovered files comprehensively "sparse"?  If so, perhaps 
the recover is busy writing nulls into the space formerly not used.
