[Bug 1175402] Re: Failure to find SSD and HDD

[Phillip Susi]

It appears that you have used these drives in the past as part of an
Intel fakeraid, and I am guessing you had the SSD set up to cache the
HDD, which is unsupported in Linux.  Simply disabling the fakeraid
support in the bios leaves the raid signatures on the drive.  You will
need to remove these if you no longer intend to use the drives as part
of a fakeraid set.  You can either do this via the bios raid utility, or
with the dmraid command with the -E switch.

Title:
  Failure to find SSD and HDD

Status in “ubiquity” package in Ubuntu:
  Incomplete

Bug description:
  Gentlefolk,

  I have a Toshiba U840W laptop with a 32G SSD and a 500G HDD. Runs
  win7. Has 200G spare space.

  I have tried to install Ubuntu and MINT off a USB flash. I get the
  same problem in Ubuntu and Mint. Currently have Mint on the USB flash.

  I have:

  1. Updated the BIOS to the latest version. No improvement.

  2. On Mint 14 performed an apt-get install ubiquity and installed 75MB
  of update.

  3. On Mint 14 performed "ubiquity -d".

  The problem is that ubiquity does not see the SSD or the HDD.

  On the first "installation type" screen it reports "no detected
  operating systems" (win7 is installs and boots).

  I choose "something else" and on the second "installation type" screen
  only /dev/sdc USB flash is displayed.

  Any file manager displays displays the directories in the windows partition.
  GParted displays all partitions and unused space on the HDD.

  I will attach log files.

  Any assistance/solutions/direction appreciated, Ian
