I think you have a typo somewhere. The --one-file-system option should
keep tar from traversing mount points (and your -tvf option isn't
going to copy anything...)

If your drives are identical you can boot the install media with 'linux
rescue' at the boot prompt, then use dd to copy the raw disk image.
cp -a or rsync should work as well as tar for a file oriented copy, and
both have --one-file-system options.
