If this is an older stick this might be the problem. List the brand and model number here and I'll look it up for you or go to the manufactures web site and see if you can find it's system requirements. I believe this maybe for a camera. Is the camera compatible with Vista is it's driver up to date? What is the make and model of the camera?
Sorry it took so long for someone to get with you about this problem.
Okay i put the duo stick into the adapter and put it in my laptop which has vista it says format disc so i do and it says that it's unable to format. So i go to XP computer and put it in it works perfectly so i dont know why it works on XP but not VISTA. Any ideas? I'm trying to format it for my PSP. So you know i tried formatting it in PSP didn't work i think it's my computer though.
