I've got the problem with my old ide harddrive fews day ago. At last i found that it's ide cable is bad and that destroy the partition table. Anyway today after recover and backup the files, I create new partition table with fdisk and here is the new table.
note: "chmod +t" adds the sticky bit, so that people can only delete their own files and sub-directories in a directory
Disk /dev/hda: 60.0 GB, 60022480896 bytes50/50 ntfs and ext3 should be fair :). After repartition, Ubuntu know only hda1 as 10GB partition[my old config]. what i forget? May be need to fotmat it first. I'm not sure how to format ntfs partition in ubuntu so i reboot to winxp, format it then turn back to ubuntu again. Now I format hda2 like this.
16 heads, 63 sectors/track, 116301 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

pnix@pnix-a7n:~$ sudo mke2fs -j /dev/hda2Last thing add 2 new partition to fstab to let it automount.First create mount point with 'sudo mkdir /media/hda2'[hda1 already exist] then find the uuid and edit /etc/fstab like this.

# /dev/hda1After reboot hda2 is mounted but no write permission for me, still has other thing to fix. I follow this guide and run command below
UUID=9EF07DDDF07DBBD9 /media/hda1 ntfs defaults,nls=utf8,umask=007,gid=46 0 1
# /dev/hda2
UUID=30bf1301-3dbd-47f0-b80e-b68047358a53 /media/hda2 ext3 defaults 0 1
pnix@pnix-a7n:~$ sudo chgrp plugdev /media/hda2to change group, add write permission and sticky bit. And that it my old ide disk is come back and ready for command.
pnix@pnix-a7n:~$ sudo chmod g+w /media/hda2
pnix@pnix-a7n:~$ sudo chmod +t /media/hda2
