Problems with my SanDisk 64GB

Hi, I’m having a problem with my SandDisk 64GB card.

I’m a SGSIII user and I formatted the card above with the android >Format< button. It made my card invisible to PC (I mean most of the memory) I’m able to see 1MB and that ain’t cool. I can see it all via my phone plugged to PC(59,47GB) but not via my card reader. Is there anything i can do to bring it back to a readable format for both PC and Phone ?

I attach some screenshots showing my issue.

Please help me
