When i connect my psp to the pc using my usb. the pc only reads the psp but not the memory card. what to do?

Question

because it says no files and only 9.0MB of space. but actually its 4gig. didnt have this problem before

Answer 1

That's impossible. When the PSP is connected using the usb cord it can only read the memory card. You can't access the PSP memory at all. You might need to format your memory stick using your PSP.
