When I Wipe Free Space the estimated time remaining is always the same whether I select Normal (1 pass) or Secure (35 passes) or anything between.
This makes me think that they are all doing the same thing. Any ideas?
Oh dear! I have just noticed that CC only Securley Deletes files which are still in the recycle bin. Others are deleted using the Normal (quick) method. This could explain everything as my recycle bin was empty when I carried out the test.
