Very, very few C programs can handle running out of disk space. This includes the operating system(s). Get close to filling up the disk, and try various things.

Just recently, I was having a lot of trouble with Windows Update hanging. I finally noticed that free disk space was low. Freed up more space, and WU started working again.

For fun, try:

    #include <stdio.h>
    int main() { printf("hello world\n"); return 0; }

and redirect stdout to a file on a device that is full. Amazingly, it succeeds!
