If you connect the uRemote to the device you can see the firmware version.
But that problem most likely related to the drive. If the drive slow for the recording it cause dropouts during recording, which means there’s huge lag becasue the recorder try to finish the process for this reason you may have a long waiting time before the recorder able to stop the recording.
If you don’t wait to finish the recording properly then you remove the drive the .set file (settings file) will missing that’s mean the uTool will not able to detect the recoding.
I suggest to use USB HDD for recording.
