I wouldnt recomend buying psp memory cards on ebay as they are mostly fakes from china and thats why you get for such a good deal. They might look real but if you try to put music or movies on them they say corrupt data. Also from what i hear they have a life of about 3-6months then they quit working all togeather. Your best bet is to go to your local store and buy one there. For a fast way to check if your memory card is a fake...insert it into your psp- move to the video icon and press the triangle button and check the information...it its real it will say MagicGate:Supported....if its a fake it will say MagicGate: Unknown. I hope this help you out.
