Does Gparted do a True Bit by Bit partition copy

view story

http://askubuntu.com – I know this isn't ubuntu specific but since it's linux I was hoping somebody here could answer this question, since I used the 6 questions a day limit on superuser. Does gparted do a true partition copy to which it copies bit by bit including empty sectors so recovery of deleted data is possible on the copy of the partition or does it just ignore and leave empty sectors.
