When using a multiformat card reader always make sure you put your compact flash card into the proper slot - and always make sure you put the right side in first. They are *not* square. Those nasty devils can slip all the way inside if you're not paying careful attention. If you are distracted and make this mistake, tipping the reader upside down and shaking it a few times *might* get it out (and cross your fingers that it won't disturb/destroy any of the high tech interior components.) If this doesn't work, a gentle prod from a pair of lab-sized tweezers may remove the jam. la la la de da.......not that I know this from personal experience or anything...just saying in case it helps someone out there someday..... ;)
