I'm selling my gaming computer to a neighbor. As much as I trust him, I don't trust any third party who might get access to the computer. So I've come to the conclusion to overwrite the free space of the SSD to permanently erase deleted files. I'm using a popular tool called Eraser. The computer runs on Windows 11.
Based on my research, SSDs automatically overwrite or "erase" free space. So do I even have to use the Eraser in this case?
I only want to erase/overwrite the free space because I want to remain the games for him.
