rsync error message

[Robert Holtzman]

Tried rsync -av /home/username /media/disk for the first time. Every 
thing appeared to go well but there was an error message at the end:

rsync error: some files could not be transferred (code 23) at 
main.c(977) [sender=2.6.9]

Running "diff -r /home/holtzm /media/disk/home" returned nothing which 
indicates they are identical. The question is what files could not be 
transferred and is there a better way of checking?

Any help appreciated.
