I just recently purchased a 4GB SanDisk Memory Pro Duo Gaming Card (the red one). When using USB connect, it is simply not detecting the full 4GB that it's suppose to have, but rather, it's showing that the max drive size is 920 kb.
I have tried to re-format it, using both the PSP and the default windows formatter, however there was no difference.
Any help would be appreciated, as I don't want to put this memory card to waste.
Thank you for your time.
