mini cd-r not being recognized by XP Pro

I recently upgraded from Windows ME to XP Pro. My
computer now will not recognize any mini cd-r discs that
I place in the drive. It will read and write to normal
blank cd-r discs though. Just not the little ones. My
digital camera uses these mini cd-r discs instead of
memory cards to store photos, so I need to get this
resolved in order to download my photos from my camera.

thanks,
Adam
