deleting the partition table after its been formatted still leaves
the file system intact and functional if you have an alternative way
( knoppix ) to go looking at it
how knoppix is finding the partition boundries is a separate issue,
but my guess is, it's probably is looking at 0x448 - 0x512 and its
corresponding entended partition definitions to recreate the "missing
partition entries"

booting the smaller disk should always work if you are using /dev/hda1
and no other partitions ( /tmp, /usr, /var, /opt, /home, (optional) /boot,
... )

it will(might) work ... knoppix does lots of [sanity] checking ...
- and you;re saying it is booting off a disk that does
NOT have any defined partitions, which was deleted after
you had installed linux on it
you're saying: "fdisk -l /dev/hda" is empty than there
is no partitions defined, but i think there it could
still work if the MBR is intact and the formated fs
