xbox specific hard drives connected with the transfer cable do not get assigned a drive letter because they are not seen as a storage device. So RBtoUSB will not recognise it. I’m guessing that Party Buffalo looks for a specific device.
The drive was not formatted since the update, so I assume it’s still the old format. The only thing that has managed to write to it was Horizon which needs local Admin to recognise the device. I’m assuming that in the system update MS have somehow changed the write method to the old HD and that Horizon was updated after this change. Annoyingly Horizon is full of adware rubbish, so had to be careful during install.
