I can also report I  had some limited success with other operating systems. I've been running PC-BSD on an old laptop since M$ stopped supporting XP. http://www.pcbsd.org/

PC-BSD uses the ZFS filesystem. You can read about how to format a usb stick to ZFS here https://forums.freebsd.org/threads/zfs-on-an-usb-stick.22379/

Recently I tried formatting my Compact Flash card to ZFS. I then transferred the files from another card and restarted my 50D. Actually it bricked my camera but I had another 50D and when I tried it on that I found that it worked just fine.

I haven't had much time to test it out but it means the 4GB limit which came from the FAT32 is no longer a problem. We 50D users can't format the cards as exFAT. The camera now can record H264 continuously up to the 30 minute limit.

Interestingly enough it also produced less heat. I shot some MLV raw video at 1984 x 830 and the temperatures were about 20-30 % lower than before I reformatted to ZFS. I shot some video at my porcine ornithology club but I haven't had time to go process it all yet but I can confirm it does load in Davinci Resolve.

Maybe someone more technical than me here or on the FreeBSD or PC-BSD teams will be able to make further progress. You can also use the ZFS filesystem on a Mac and Linux so this one might fly.

I have a 50D and this is very interesting. But the bricked part freaks me out a little. How did it happen? And how can we avoid it? )
