New question #78309 on Ubuntu:
https://answers.launchpad.net/ubuntu/+question/78309

Installed Seagate Barracuda ES 2 Terabyte drive. Installed Ubuntu with no problems save the one. I'm using a fatal1ty-an9-32x motherboard with nVidia chipset, AMD duo 2 +4800. 

Debian reports the same size (137 gb) for the hard drive. Windows XP sees the drive correctly at 1 terabyte.

The firmware on the hard drive is up to date according to Seagate Technician. Seatools for Dos and BIOS see the drive as terabyte. BIOS has latest firmware update (rvision 19). 

In Seatools for Dos it shows the harddrive using Max native address. If I manually reset in Seatools for Dos the Max addresses, I see the whole drive in Ubuntu. If I reboot again it is lost.

Grub geometry shows:

grub> geometry (hd1)
geometry (hd1)
drive 0x81: C/H/S = 16709/255/63, The number of sectors = 268435455, /dev/sdb
   Partition num: 0,  Filesystem type is ext2fs, partition type 0x83
   Partition num: 4,  Filesystem type unknown, partition type 0x82
   Partition num: 5,  Filesystem type is ext2fs, partition type 0x83
grub> 

Which shows some of the partitions. One is missing, a swap partition for another version of Linux.

Fdisk is unable to read the drive:

My first drive has Windows XP. Seatools for Linus shows:

paul@ubuntu:~$ sudo fdisk -l

I've tried to reinstall grub with the --force-LBA, didn't work. I used grub geometry to set the cylinders heads and sectors - didn't work. I've reinstalled several times - didn't work. 

I would really like to use the whole drive. Hope you have some ideas.
