hi, all my pc cant read or discover the sony memory stick duo card of my sony camera ... is there any chances for this to be f

I take it that you have tried the memory stick duo in multiple computers and it works in none of them. Is this correct? Can you still use it to record pictures or video with the Sony camera? Are you using an internal card reader on the pc's or an external one? If an external reader have you considered trying a new or different reader?
