cd /newdisk
find . -type f | sort >/tmp/newdisk.lst
cd /olddisk
find . -type f | sort >/tmp/olddisk.lst

diff /tmp/olddisk.lst /tmp/newdisk.lst

If you want to check if files are identical, you can do:

cd /newdisk
find . -type f -exec md5sum "{}" \; | sort >/tmp/newmd5.lst
cd /olddisk
find . -type f -exec md5sum "{}" \; | sort >/tmp/oldmd5.lst
diff /tmp/newmd5.lst /tmp/oldmd5.lst

The two lists need to be sorted as the
file order might be different between the
two file systems.

Maybe cp had problems recognizing sparse files
correctly?
