[Bug 924914] [NEW] Installer does not detect the hard drive during installation

[Marco Lackovic]

Public bug reported:

The Ubuntu 11.10 @ 64 bit installer does not recognize/detect/see the
hard drive. When the "Installation type" step is reached, the panel --
which was supposed to show devices and partitions -- looks empty.

A "sudo fdisk -l" shows only /dev/sda1, the USB drive from which I am
running the installation. The following two solutions did not fix the
problem:

- sudo apt-get remove dmraid
- switch the SATA mode in the BIOS from IDE to AHCI

It's not a hardware related problem as I have already successfully
installed another operating system on the same computer.

As workaround I went in the BIOS and set the SATA Mode to "IDE" and the
SATA3 Mode to "AHCI". After doing this the installer did detect the hard
drive and installed Ubuntu alongside the other operating system. It is a
workaround and not a fix because the other operating system won't load
with the SATA3 Mode set to AHCI, so every time I need to switch OS I am
forced to go in the BIOS and change the SATA3 Mode.

Hardware specifications:

+ Seagate ST500DM002 SATA internal hard drive (the SATA cable is black,
the plug is white, named SATA3_0 and located nearby the RAM slots)

+ ASRock H61M/U3S3 motherboard
