<q>I'm curious, why do you think crc is popular? Sure, your harddrive/os/filesystem/browser... use it, but they use md5 and sha1 too</q>

Ah.. it is just cultural. SHA-1 and MD5 are more accurate but they tend to be alot slower and also less known. You can kinda think that SHA-1 and MD5 as Python and Ruby, while crc32 being Perl. You see altought Python and Ruby are getting popularity, Perl is still as twice as popular compare to them.(accoding to an usage statistic by some websites)
