Hardware RAID controller, disabled in card BIOS (no volumes in array), two HD's connected, both at same size, working as normal IDE A and B with completely different partitions.
Fdisk -l after booting from desktop CD shows both drives as expected (sda/sdb with all partitions), gparted looks fine, too. No RAID mapping, no fakeraid, normal IDE behaviour.
Starting installation and choosing manual partitioning shows only first drive as mapped devices. After installation sdb became a real clone of sda and both are combined as a RAID array (I tested with forensics, the contents are the same on both disks).
I expected the same behavior as netboot and alternate install offers: You have to activate RAID *manually*. Automatic activation of RAID array (how? controller is still "unconfigured" in its BIOS) may be highly insecure for unexperienced users because of the risk of data loss. What confuses me is that the methods for experienced users (alternate/PXE) contain a simple switch, while the way to work around under graphical interface is uninstalling dmraid in the running live system via aptitude and remove dm_raid45 module afterwards manually. Then both disks will show as expected in manual partitioning.
If it's not a bug but a feature, it should be clearly documented in the installation process I think.

I think this report needs details of exactly what the hardware RAID controller is.
I *think* running ubuntu-bug -u 592892 should update this bug with details of your system, if it doesn't
then please include the output of lspci -v and sudo dmidecode and dmesg
