Re: Ubuntu wont detect hard drive
Just a hunch .....
those 3 partitions you mentioned, are they all primary and is there any recovery partition that you may not have mentioned?
What I'm leading at is that I seem to recall a thread wherein karmic will not insist on installing when the max partition limit has been reached.
If this hunch is right, try deleting the ext4 partition, keeping it unallocated and then see if the liveCD will recognize. If so, then just install in largest unallocated space.
Also ... why the command sudo apt-get -y remove dmraid instead of sudo apt-get remove dmraid?
