Hi *,
a few days ago I added a new 120G disk to my older machine and
partitioned it with cfdisk. But later on (after moving all data to
the new disk) I saw, that the partition-table wasn't really
consistent:
,---- [ sfdisk-dump before repartitioning ]
| Disk /dev/hde: 14946 cylinders, 255 heads, 63 sectors/track
| Warning: The first partition looks like it was made
| for C/H/S=*/225/63 (instead of 14946/255/63).
| For this listing I'll assume that geometry.
| Units = cylinders of 7257600 bytes, blocks of 1024 bytes, counting from 0

Apart from the fact that I still don't know, how this could happen, I
hopefully used only hde7 and up for my data. So this should be no
problem: just a fast (stupid) 'fdisk /dev/hde d 5 d 6 w'... and my
data was gone...:(
Sadly my attempts to restore hde7 with sfdisk didn't lead in the
wanted result.

It's the same as before, but still hde7 can't be recognised as part of
my "vol1":(
At this point came my second fault(?): In my desperation, I tried to create
hde7 again with pvcreate...
How can I restore this partition? With hexedit I've seen, that there
still exist some copies(?) of the "superblock"(?). But sadly I don't
know, what exactly I need to copy...
thanks
Heiner
p.s.: I'm not sure, if any more information could be helpful. So
please tell me, what I should post...
