Unless I am mistaken, the model is delivered or XD memory of the model ordered corresponds to SD.Il type memories follows that inserting my photo memory card into the reader and then inserting it into the computer when I click to open the removable key I get the message "Insert disk in drive". Conclusion: This purchase is of no use to me because I do not know what is an XD memory. Can you tell me or tell me what I should do? Thank you.
