I don't want it to retrieve the data so often because I'd still be using the hard drive for a long time... And I don't know what that has to do with the problem. As you can see, it's just a display error...
I've tried everything, reinstalling, the non-Beta version, the Beta version. I deleted the LAN connection, re-created it. Nothing. It doesn't show the temperature of this hard drive only, but only on the LAN. It shows it on the host machine.
When I connect to the other PC via LAN, it doesn't show the temperatures of one of the hard drives, even though the temperature is visible on that PC. However, it doesn't show when connected via LAN. Everything else is visible.
