View ---> Tray Icons --> Disk usage (text)
How do I choose which Disk I want to be monitored in the tray? It's only doing my C. I need my D more importantly, or both at once. I saw another post that suggested opening the plugin options for Hardware Devices, and ticking the drives on, but I can't open the options for any plugin. They are all greyed out. I did enable both drives under Options --> Disk Devices, though I don't know what that did.
