Well no, that obviously does not follow: something else besides FAT32's 
well understood 4Gb size limit is coming into play here if you think 
about it.

There is no way your camera is recording ~9 minutes of HD video on to a 
64Mb SD card.

With 64Mb of storage available depending on how you define "HD video" 
you're going to get seconds, not minutes. I would guess that either your 
camera is taking some diabolical liberties with what it considers "HD 
quality" or your methodology is wrong. Does the camera also have 
internal storage it uses as well?

Can you recheck and confirm your results because something here does not 
add up and for once it's not FAT32's fault...

Cheers
