i have bought a new card and solved the problem finally
the difference between two cards is when i insert the new one zaurus mounts it automaticly, but it does not mount my other card automaticly i think this is the main problem
also when i started the NAND restore it gives the format error couple of times but when i tried it for the third time without chancing anything it restored without a problem , hard to understand but whatever i am happy to make my zaurus working again
