[Bug 1019872] [NEW] Devices which were a part of quasi raid are not displayed in partition configuration.

[Marek Dopiera]

Public bug reported:

When installing kubuntu 12.04LTS, my SATA HDD connected to a controller
of H77 Intel chipset was not displayed by the installer. I could not
see/edit its partitions etc. and thus install the system.

I have found out that this happened because the HDD was a part of a
quasi RAID (Promise PDC20376 FastTrak 376, dummy 1 disk RAID 0)
previously. The remedy was to overwrite the RAID signature with zeros
(several last sectors of the HDD). After doing this, the HDD became
visible and installation has finished successfully.

I don't have any logs unfortunately, but neither of the files located in
/var/log/installer contained the information about this issue.
