I am running Windows Vista on my Dell laptopn that has a camera and a card reader built in. But if I try to insert the memory card in the slot then it will not get recognized at all in the laptop. If I plug it in and then we can hear the sound of a usb device which is being recognized by windows and also the safely remove icon shows up in the quick launch area, but card doesnt appear in Windows Explorer. When I go in to disk management then it shows up as a removable device but there are no letter assigned to it when we try to format it and if we try to format it then disk management says that there is some kind of error with it and I have to restart disk management or the computer, and even doing this it wont work. I have already tried to install the memory card drivers but that didnt work either. Is there anyone who can help me out?
