Virtually all the news stories state that Hillary erased. Does anyone having an inkling as to whether the emails were merely deleted or has all free space on the server been overwritten one or more times?
There is no reason to think the emails can ever be retrieved. Heck, check out "Giveaway of the Day". The free software today is a file washer to make sure deleted files can never be recovered. If the software is out there for free, why would she leave files for anyone to find?
