4G sony mem stick pro duo high speed unable to read by computer

Try replacing your memory stick because it might be broken or corrupted.

try using firmware 5.32

maybe you place it in the wrong folder..or memory card is busted

Ive been having the same problem with my 4GB Pro Mem stick when you put it in does it say 0kb left?

try using a different usb port, if its not usb then try getting a pro duo to usb that should work for you

Also, please check your card reader if it supports Memory Stick Pro Duo.

If you already have an adaptor but still doesn’t work, you can buy a PSP USB data cable to transfer files between your computer and PSP.

there is not support for a memory stick more than so big, i dont recall the exact size but try using both mem sticks (i.e take some of the homebrew apps and use them on the other mem stick then delete them from the stick you want to try with) should work have had this preoblem before

u need to format memory stick. to do this go to system setins then go to format memory stic.before doin this make sure no files ar on the memory stic as they will be deleted.                                            PLEASE RATE ME 4/4. THANKS

Turn the psp on go to system settings then format memory stick then insert the memory stick and format it and it should be fine.
