iPad iOS/iPadOS 13 External USB Storage in Files App

[Keith Weisshar]

I have a 10.5 inch iPad Pro with Lightning Connector and bought the Lightning to USB 3 Camera Adapter. I plugged in my DC powered 8 TB USB 3.0 external hard drive into the USB port but it isn't recognized in the Files app. The only way to get it to work is to delete and create a new exFAT partition of ‭4,194,303 MB or less‬. Any more than this amount will not work in iPadOS 13.2. Is the 4 TB limit an iOS/iPadOS 13 limitation or the limitation of the Lightning to USB 3 Camera Adapter?
