Seriously? When files are deleted, their sectors are simply released to the free space pool without erasing their contents. Allocation of disk sectors without clearing them gives users/programs access to file contents previously stored by other users/programs.
No worthwhile filesystem will allow you to read a block of disk that you haven't already written to. Once you've written to it, any existing data that was there is overwritten. The same isn't true for block-level access, but as a rule that requires admin access, and once you have that all bets are off... Scott
