N70 memory card issue

Hello,
i'm having issues w/ my nokia n70 music edition.
before i had it reformat,the gallery option will not display anything saved on the memory card or even on phone memory.but after reformatting the phone,it seems to be working fine already until just recently it will no longer read the files on my memory card.but the files is readable in another phone or even in pc.

is it something with the phone or should i try it with a different memory card?the memory card i am using right now is not the original memory card that it came with since the original also was corrupted.or its really with the phone that is having issue?
