Imagine downloading a large file in many small chunks from many different 
servers.

In the end, you might sit there with a huge file with a bad checksum without 
being able to pinpoint the single small chunk that had the error. So now you 
need to redownload the whole thing again, instead of just regetting the small 
chunk that contained the error.
