You're probably missing all your hidden files.

Bash expands * before calling scp and does not include hidden files.

Check with `du -chs *`, which will only compare visible items. There
may still be a slight difference due to block sizes (as John
mentioned) but should be pretty close.

Did you compare output of `ls -a`, or just `ls`?

I'd try again and copy the directory itself (instead of the files
within it). You could use rsync to save yourself re-transferring about
20GB.
