I formated my Nikon D70 Compact flash card. Any chance for unformat?

Does Nikon D70 format the CF card to the factory settings with 0x00000 all over?
Is it possible to unformat it somehow using a software.
Tried e few programs unsuccessfully. Every time it said ''Empty''
Any Advice or recommendation?

Added (1). Does NIKON D70 do low level format (wipes everything clear) or is doing just a quick format (easy to get recovered) ?

Both are the same
the low one does a cleaner job
it clears more fragments
just like defragmenting the computer
