Thank you very much for answering, I have been away from the computer for a while. I run Mathematica v12 on Raspberry Pi 4. Well, I think you are right, speaking of large variables. There are a few long lists of words (300 thousand). I will look into the space that they take and compare it with free...

Thank you for your answer/question. No, I am not overclocking at all. I turn it on, run a Mathematica notebook (program) and it works fine. Then suddenly the variables are reset. And the mouse drifts over the screen. That is what happens. Could it be a spike in the power supply? I have the official ...

My Raspberry Pi works fine running a Mathematica program with quite large variables (thousands of words). But after a while it suddenly resets the variables (but does not hang). Other times it takes forever to solve the next line of code. Any suggestion would be much appreciated; thank you very much...

Thank you very much, I think this solved my problem. I can see the Hard drive and can copy files into it.
Awesome. I am a very happy customer

Many thanks for the posts that seem to address my question... but they do not help because I cannot see the hard drive.

I can see the disk in File Manager but it does not allow me to put files on it (Permissions). I have ...
