I posted this on a more psp-specific board/site, but if anyone here has any help/suggestions to give, I'm all for them. I recently bought the Photofast CR-5400 microsdhc to pro duo adapter (from shopdigi.com). The only reason I bought it was because I was having trouble with formatting issues with previous adapters (like the one from dealextreme, or ebay ones). Anyway- I have an A-Data 8GB Class 6 microsdhc card, and a Sandisk 8GB Calss 4 microsdhc card. At first, the microsd cards in the adapter...then placed in a memory stick Duo adapater would be read by my pc (15GB! Hooray!). But then, when I try to format it on the psp (slim, purchased before the new-board-models, and 4.01 M33-2), either it won't read the card at all, the memory stick light will just keep blinking (not Fast blinking like when it's reading the card), and/or! when I try to format from the psp, it'll give me the 80020321 error ("There was an internal error" or whatever), or just say that there isn't a memory stick at all. I'm not sure what else to do. It Sometimes will read from the psp-usb connection, but recently (as of last night and this morning) it's not even doing that anymore. Suggestions? Help?
