** Description changed:

BTO: 10.10 A02
Platform: Krug Problem has so far been observed on Krug, but the other platforms (Vida and Macallan) share common components and BIOS code and may also be affected.

Summary: With certain 512 sector and 4k Sector Drives in 512e mode, the
systems fail to boot after installing the Operating System.

The issue has been observed on two Seagate 4Ke drives and one 4Ke
Hitachi drive with the following model numbers and sizes:

ST9500423AS 500GB
ST250LT007 250GB
HTS547564A9E384 640GB

One 512B Hard Drive from Hitachi was also found to be problematic:

HTS723232A7A64 320GB

With the Problem drives, the following is observed with these BIOS
settings on the Krug / Latitude systems:

AHCI Mode - The Factory Image downloads and appears to install fine,
but afterward the systems won't boot the OS. We are dropped to a grub prompt or a black screen with blinking cursor.

Raid On - Works without issue (Macallan has the RaidOn option, Krug does
not).

ATA Mode - Works without issue.

Natty also appears to be affected by this as well. We get similar
symptoms where the OS doesn't boot afer a seemingly fine installation.

Steps to reproduce:
1) Install Maverick or Natty onto one of the above disks.
2) Reboot

Actual result: At this stage, the system is either dropped to a black screen (as observed in the factory installations), and if Grub is installed to the MBR of the affected drives in AHCI mode, we are dropped to a grub propmpt.
Switching to either ATA mode or Raid On (in selected systems) allows the OS to boot just fine.

Expected result: Operating System boots regardless of the Mode in the
BIOS with these hard disks.

The drive that I have with me in the Krug is a:

Seagate Momentus 500GB SATA disk. The model appears to be ST9500423AS
with a firmware revision of 0001DEM1
