Okay..extreme newbie here..as a matter of fact just got reader today and have actually been playing with calibre for a week before the reader came! When I usb my reader calibre recognizes the reader and it is put up next to my library for viewing just like it should be. When I have an sd card (kingston 1gb) in the reader it does not recognize the card. My computer does because the normal "plug and play" prompts come up. The "send to storage card A or B" is not available. What has a newbie done wrong?! Oh and if you need to know I am running newest beta version of calibre on Vista. I have tried putting the card into the reader before it is hooked up to computer as well as after. Someone help a noob....be easy! (I am nearly computer illiterate as well).
