Why won't parted copy my root ext3 partition?

[dalchri]

I am using parted 1.6.22 on the FC4 rescue CD. The installation is RH9 on /dev/hda1. As a test, I am trying to copy /dev/hda1 to /dev/sda1. I get the "strange layout" error message from parted.

parted output for /dev/hda:

Start End
0.031 2000.000

so I create the exact same size on /dev/sda:

mkpart ext3 0.031 2000.000

then

cp /dev/hda 1 1

Is there a special ritual involved when copying the root, boot filesystem?

I've even converted to ext2 like this:

tune2fs -O ^has_journal /dev/hda1
e2fsck -f /dev/hda1

And I still get the same error message when I try cp from parted.

Any ideas?
