Depends a bit on your abilities of writing scripts yourself.
With "cygwin" (or even busybox or minsys) on a windows systems you can do the task with
a small set of simple commands:
Given you have a directory "DIR" on the internal drive that you want to
compare to the backuped dir BKUP-DIR on the external drive, you could run
cd $DIR
find . -name \* -print |
while read fname
do
md5sum $fname
done >result1
...
do the same in BKUP-DIR (with redirection to result2)
and then
diff result1 result2
...
this should show missing files as well as additional files and
also files with different content.
