Re: Can't access old partition with Lucid after installing 12.04
From what you show, you only have 1 ext4 partition on that drive, so somewhere along the line installing Mint14 or 12.04, you no longer have a Lucid partition. I always manually partition before (gparted) or during install, so I know what is happening.
Not sure if testdisk could recover any Lucid files after partitioning and installing other operating system(s) over it.
