cat < /dev/random > ~/Desktop/Scramble.dat

Watch the file size in the Finder until it's about a GB or so in size.  Kill the cat with ^C.

Now, take that file and duplicate it in the Finder.  Select all, and duplicate again.  Keep doing that until you've got >120GB on the disk.

Now use the 'cmp' tool to compare the first file you made with the last one that was duplicated.
