i got a 16 GB Micro SDHC card, and the mentioned adapter in the subject; i put it in the adapter in slot 1, and i put it in my psp to format
naturally, it tries to format but it says there is either no mem stick, or it says “format failed” (80220087)
also, when i put it in, strange enough, it says there is 14 GB of PSP memory left (it isn’t formatted at that time, or is it?), and i can usually use it like it is if it was formatted, but there was a difference between my 1 GB card, and the impromptu card
my 1 GB card had these file filders named PSP, VIDEO, BOOK, and so on and so on
but my photofast 16 GB card (i have a 16 GB Micro SDHC card [sandisk brand] ) doesn’t have ANY folders on it
also, if it helps by any means, i got the adapter on ebay; it said it was new
