[gnuwin32 - Help] Verifying checksum of a CD

I have an ISO file that I've burned to a CD.  I know its md5 checksum.  On my
Ubuntu 9.04 system I can do

dd if=/dev/cdrom | md5sum

and I get the same checksum as for the original ISO file.  However, on my Windows
XP machine with CoreUtils 5.3.0, when I do

dd if=\\.\D: 2>nul: | md5sum

I get a different checksum (D: is the drive letter for the CDROM).  I get the
same result if I drop the "2>nul:", but the stderr text gets from dd gets mixed
with stdout from md5sum so it's more tricky to read the checksum.

Can anyone see what I'm doing wrong?
