Unable to write to file, because it appears to be corrupt.

I am doing a long calculations and they keep being interrupted constantly at random (as i assume) places. When re-running the code to save the ""corrupted" file once again, it without any problem. then, the problem repeats itself further down the file numbers. Due to the fact that the file is saved after re-running of the code, i assume it wasn't corrupted in the first place. So i don't really know what exactly the problem is. Would appreciate some help or suggestions. thanks!

Do you have enough free storage space on your partition ?

yes, definitely. I save the files to my lab server, so it should not be an issue, i think

That is a bit ambiguous.

If it happens to mean that you are using a remote filesystem to save the files, then you might be encountering a glitch in the remote filesystem. Best practice is to always write files locally, and then copy the completed file to the remote server.

Hm, will try that, although I am not sure it will work memory-wise. But we will see. Thank you!
