So... I tried to back up my Documents folder. this file named cellranger just halt the copying process. it's from this:https://cran.r-project.org/web/packages/cellranger/index.html since I just installed the R package in my documents previously because I did not give the program admin access. The problem right now is that the dialogue box for cancelling is not showing any response. The fan RPM is high (though looking at the task manager, neither disk nor CPU shows overutilization. GPU strangely show some activity though. I don't think it's related to GPU. So... it's something strange? if it helps, I am trying to copy file from my second SSD to drive.
