Rewrite partition structure

Hi!

After a blackout i discover that 3 of my disk had the partition table destroyed.

-One its a 2T disk with HFS partitions on.

-The other two are 300 G disk with ext2 partition on (i use that on a linux olso)

My computer is a laptop 2.16 GHz Intl Core Duo. Mac Os X version 10.4.9


When i try to rescue them with disk utily i discover its useless because it cant see the partition table, so it just belive its a empty disk. I had no more luck with other program for rescue files like "Data Rescue II"

Then i use testdisk and discover a good thing. That program can see the "right" partition table in some way.
For example it tell me:


Disk /dev/disk1 - 341 GB / 317 GiB - CHS 41503 255 63
Partition Start End Size in sectors
P HFS 1824 19231 17408
P Linux 19232 666729623 666710392

And i am quite sure there is right.

BUT... when i try to write down the partition table it tell me:


Function write_part_mac not implemented
Use pdisk to recreate the missing partition
using values displayed by TestDisk


I try to use pdisk... but i cant understand it.

How to use it to write the partition table without format the partiton?

I think testdisk gave me all the imput, i just need to know how to fix the disk with pdisk.

I read many document about... but i am quite a noob.

Please help me.

It VERY importat to me since i loose almost 3 T and there were all my important thing there!!

Thanks!

PS: Sorry for my bad english.

Try Alsoft's Disk Warrior

Disk Warrior can work only in partitions. But if he cant see the partition its useless...
