Last year I sold my psp, but few days ago I got a new one and want to use my old memory stick 4gb. So far, so good. But when I connect the stick via card reader or the psp and start copy something on it (demos, videos or music) its really slow. It takes around 25 mins to copy 2.36gb. My windows7 displays exactly 1.5mb/s. I tried to format the stick from the psp and the pc, but with no result. I tried it on several PCs and a laptop - its slow. But if all my usb pendrives works very fast on the same PC. Its like the memory stick itself is working at usb 1.1 speeds :( Any ideas how to fix this? Thanks!
