Partition Table Erased, Machine still running

Hi Folks, I erased the partition table of a running machine. Shame on me. Machine is still running though. There _must_ be a way to get theinformation from the running kernel. As fdisk states: "The kernel still uses the old table" I tried /proc/partitions, but can't seem to get the cylinders right. At the moment I am copying 120GB data over ethernet, which is kind of tedious. Anyone ever recover from this ? Regards Dan
