If you had just one partition that filled the whole disk, this should be
not difficult to recreate.

To recreate a partition that have gone missing or been destroyed it has to
start at the exact same sector that it was originally created. Ideally
it should also
end at the same sector, although the partition could also be made
bigger than the
original as long as it is not entering any following partition.

The start/end numbers above are not exact sector numbers so I would like to
have some more information. Could you run parted and print the complete
partition table using units s, cyl and chs? The two latter units can
be calculated
from the sector number, but it is much easier to let the computer do it :)

Also I would like to see the raw content of the partition table. Could
you run fdisk
with commands "x" and "p" to print the raw partition?
