My Personal computer reads the above & also SD cards. The memory stick duo reader has suddenly stopped working and I dont know why. When I insert card it seems looser, and my pc doesn't seems to recognise it's there. There aren't any messages at all - not even error messages. Also, a green light usually goes on once its connected but that no longer works. it still works fine for the SD card. Any suggestions how to repair this? Thanks Babs

Answer:
The only thing i can think of is either dirty pins or the pins are bent

Blow into the card reader slot for ProDuo, if that doesnt help

Check inside to see that the pins are all straight and even, pointing outwards.. ie not bent

Happened to me once, used a pick to straighten the pins again

Hope that helps a bit

Answer:
it seems to me that ur memory stick pro duo slot in the card reader is broken. there is no way to fix that problem unless u just buy a new card reader. srry.
