You need to use '/sdcard/' not '/sdard', the former says to push it into the directory '/sdcard', the latter makes it replace the symlink file /sdard/ with the file you just pushed. This is what happens for me when I just tried this, and I've not noticed this before because I've always used '/sdcard/' as is my habit with these sort of things to avoid ambiguity of whether you mean a directory or file.
