Security question

[Florian Bogeschdorfer]

Hi Ruslan

You once told me that if I delete a record, it will still be there
physically, just somehow flagged and not appear anymore. Now with a hex
editor I could still recover the data.

Now I wonder what would happen if I overwrite the record with empty values
or "XXX" stuff before I delete it? What yould appear in the hex editor? The
empty or XXXed record? 

Best regards, Florian
