Ubuntu Installer can not find my SATA drive: I recently experienced a
problem installing Ubuntu on a particular computer. Ubuntu's Ubiquity
Installer could not detect my SATA drive, although sudo fdisk -l found
the drive just fine, and the drive also appeared in gparted. As it turns
out, the SATA drive had left over raid configuration information that
was telling the installer to skip the drive (as if it was unsupported).
In the following tutorial, I will show you what I did to get Ubuntu to
detect the SATA drive, so that I could proceed and install Ubuntu.
- Boot Ubuntu from a Live CD or Live USB
- Open a Terminal (Applications > Accessories > Terminal) and type sudo su
- Type fdisk -l (note which device is your SATA drive)
- Type dmraid -E -r /dev/sdX
(Replacing X with your actual device found in step 3) - Confirm that yes, you wish to remove the dmraid information
- Return to the desktop and proceed to run the Ubuntu Installer
