What will I do If My computer can't read my PSP?

My micro sd card converted through a memory stick pro duo adapter will read on my computer but not my psp?

• i have this adapter http://www.waysale.com/micro_sd_to_ms_pro_duo_memory_stick_adapter and it reads/writes fine in my computer but when i plug it into my psp it says "the memory stick cant be read, go to x menu to format". i never formatted the card while it was in the adapter, but i was under the impression that it should work if it is in fat32. on a similar note, has anyone tried using a 64gb microsd card in a memory stick converter? especially in a psp?

• Answer:

  You have to format the "memory stick" while in your psp, not your computer. This is the only way the psp will be able to recognize it and if you take it out of the psp to use in another item (camera, computer, etc) you will have to reformat it before it will be recognized.
