My PSP (PHAT version 2.71) has been untouched for a very long time and I thought I'd have a go at installing custom firmware, so I updated from my included 32MB stick and ordered a 8GB Pro Duo Ultra II from Amazon. Anyways, when I first got it, I went to the in system option to format the memory stick and I did, however when I connected the USB it didn't respond like my other card did. So, I then went to My Computer and then its removable drive, and it says that it has not been formatted and when I click yes to format it only gives me the option to format it to FAT32 (which I've heard is not what I want) and to 3.51 GB capacity which is much lower than its capacity. And as for it being fake or not, I looked at the card's information on my PSP, but the information for Magic Gate capability is not there (meaning its completely blank of the words "Magic Gate" on the screen) , just "User Capacity" and "Free Space" are there, but I suspect this has something to do with my firmware being so old. So, I don't really know what to do. I'd appreciate any help!
