for the last 2 days i've been having a smart event pop up saying "Sata disk on controller 0 port 0 at risk" and I decided to run a gsmartcontrol and this is what I got as results, should I be worried?

Since it looks like you are running Linux, you can't run the manufacturer's tools easily. That is really the best answer. There is no way to know if this linux tool is accurate for this specific device.
Then why would you choose a sourceforge open source tool? Get the tools from the Toshiba website.I'm not running Linux i'm on windows 10
