syncup or compare 显示文件不一致，但下载下来比较却是一致的

[qiqjiao]

最近同步了一个文件夹（一共有几十个视频文件，总共29G），syncup老是说有个文件不一致，然后重新上传。试了几次还是这样。我下载下来和本地的比较MD5却显示是一致的。用compare一样，老是说这个文件不一致。我一开始怀疑是不是这个文件特殊，然后"echo 0 >> path/to/file"，然后重试，结果还是说文件不一致。

下面是命令还有一些输出：

$ bypy -e -v syncup /cygdrive/e/Movie.TV/Spartacus /Movie.TV/Spartacus true

今天又同步了一个文件夹，一共18个文件传完后居然提示有10个文件不一致。手动下载下来比较md5却是一致的。看来这个问题发生的还相当频繁。

这个貌似是因为百度那边的哈希算法有改动，之前有牛人分析过并合并了他提交的代码，但是如果百度再改哈希算法的话，这个问题可能还会出现。
