Did you first format this card with fdisk?
did you give it the exact same info this time around?

Can you read /dev/'sdcard' ? (sdcard being the device in the dev directory
where the card lives)

If yes can you run hexedit -s /dev/sdcard1  in a terminal as root?
and go to address 0400 - 04B0 to see if nilfs still exists?

be very careful no to save any data in hexedit, it will definitely and
finally
destoy your data.

0400 looks vagely like this:

the 34 34 in the top line say this is nilfs.
