The three devices support all types and sizes of sd/sdxc cards. However, only the 64GB version supports exFat on those. I believe it's disabled simply because of the licence fee. I read somewhere that it's something like $300 000 flat fee + $0.75 per device to legally ship with exFat support.

I guess getting a root access to the device would also help for simply enabling exFat (or even other FS) support to the 16/32GB model. I also tried to telnet it but the service doesn't appear to respond. Though as previously mentioned, I'm not a hacker at all so maybe I didn't try it the right way.

Cooper, I have the feeling you're answering to me without actually reading me :) I know I can format the card with exFat, but as previously mentioned, Sandisk limits Wireless Connect drives bought with 16 or 32GB of storage to FAT32 compatibility only. When you format an 64GB or whatever the size SD card in exFat and you put it in a Wireless Connect Flash drive that initially shipped with a 16/32GB sd card, the wireless functionality of the drive is disabled, you have an error message on the iOS app inviting you to reformat your sd card on a "supported format". That's the reason why they distribute two different firmware branches. This limit is supposedly wanted by Sandisk to incite you to buy a 64GB version instead of buying a 16GB model for half the price and put your own bigger SD card. Or it might be because they don't want to pay the exFat licence to Microsoft for their smaller storage versions.

Cooper : The idea is not to get 64GB from a 16GB which would be unrealistic. But actually replace the 16GB sd card with a 64 or 128GB sdxc card and be able to use exFat. Currently Sandisk limits the 16 and 32GB version to FAT32 file system for some reason, hence the difference of firmware versions provided for 16/32 model and 64 model which is the only to support exFat. I guess this might be a licence cost issue (exFat is Microsoft after all). So the idea is to override this firmware limitation for model AO2S.

Hi Guys, Not a crazy hacker here but I see there is discussion about hacking the Sandisk Wireless Connect. As one can see on : http://kb.sandisk.com/app/answers/detail/a_id/12713/session/L2F2LzEvdGltZS8xNDE0NDk3MzYxL3NpZC9wQm1sNV81bQ%3D%3D There are two firmware branches for the Sandisk Wireless Connect Flash Drive : 16/32GB (AO2S 1103) 64GB (AO2E 1103) I guess both models are exactly the same in terms of hardware so I wonder if there's an easy way to force the firmware of the 64GB model (AO2E) on the 16/32GB (AO2S) model. That might help to unlock exFat support for model AO2S. That will allow anyone who already has a 64 or even 128GB card to buy the 16GB model and expand it to 128GB while gaining exFat support. Trying to rename the "wfd1103e.df2" as "wfd1103.df2" and putting in the drive for upgrade does not seem to work at all. No success in trying to edit the file, maybe there's need for some specific hex editor to actually be able to modify the identifier. Any ideas ?
