It appears the cards I have is faster or something.  ;-)  Those class 10
cards are the fastest I think.  I got them since it throws video onto
the card.  I got one that should work fine in a video camera, since one
trail camera is essentially that.  I used Device Notifier to unmount. 
It took it a second or so but it said it was safe to remove.  From my
understanding, it syncs the file system before unmounting, right? 
Surely it wouldn't unmount if the files were still being changed, right? 

I may change the cards tomorrow and do some more testing.  I'm curious
as to what is up with them.  I wasn't sure if that is a sign they are
going bad or just some weird quirk. 

I'll try deleting just a couple pics or a single video and see what it
does.  I'm not sure it will matter but it's worth testing to see. I'm
curious if nothing else. ;-)
