UDF doesn’t work that well for true R/W storage, it’s more suited for appendable or rewritable storage and from my experience the format is so bloody fragmented version wise that half the time when you format it on one OS you don’t know what will work on the other, sometimes the other would read it just fine but won’t be able to modify it without reformat in some cases modifying it makes it unreadable on other devices, it’s quite a mess...
