In general, the occurrence of disk fragmentation will not do harm to your operating system, but it can slow down computer performance, for instance, your PC takes a long time to boot up and respond you at a slow speed. In addition, you would also suffer random crashes and freeze-ups. If you are annoyed with these problems, you may as well analyze your disk, clean up junk files and fragmentation to improve your system performance.
