If you have the original Quadra (not 4K), see here.
There’s a bug somewhere which stops the log tidying working correctly on some installations of HamClock, including the Inovato Quadra 4K.
As a temporary fix, it’s possible to start HamClock with logging disabled and this will describe how to do that.
First, close HamClock. Click the padlock on the main screen, select Exit HamClock, then click Ok, and then Ok again.
Now you need to get to the terminal. You can do it either from the desktop, or from a different PC using the SSH command.
Enter the following command to delete the existing logs:
sudo rm .hamclock/diagnostic-log*
If you are prompted for a password, it is 1n0v@t0
Then enter the following commands:
sudo cp /usr/local/bin/hamclock-runner /usr/local/bin/hamclock-runner.old
sudo nano /usr/local/bin/hamclock-runner
If you get this message, just press enter.

You’ll get a screen like this:

Now you’re going to modify it to add the -o switch twice, directly before the -f switch. Use the cursor keys to move around and type -o (that’s a dash and a lower case letter o) before -f.
It’ll look like this:

Check, double check and check again to make sure you’ve done it properly.
Press CTRL-X, you’ll get a prompt that says ‘Save modified buffer?’, press the Y key and then press enter.
Now reboot your Quadra.
sudo reboot now
Your Quadra will restart, logging is disabled and the internal flash memory won’t fill up.
If you do a master factory reset on your Quadra, you will need to repeat this process, and when this issue is resolved, you will need to restore the backup copy of the runner file.
