Original FAT32 only natively only supported 32Gb partitions, while newer versions can go up to 2Tb. I’m not sure what dLive’s limitations are but try creating a partition just under 32Gb and see if it is recognized.
I’m only making a guess here, as the only devices I’ve ever used with dLive are USB sticks, and not SSDs.
Also, I’m not sure if you’re using Windows to do this, but if so, try using a tool like GParted or something similar, since Windows sometimes does it’s own thing.
You can also reach out to A&H support support@allen-heath.com and see if they can shed some light on this for you. Good luck!
