Clearing Raid Status Before Linux Install

If you have previously used a hard drive in a raid enviroment and are now using it as a standalone drive in an install, sometimes the install fails / crashes at the hard drive / partitioning screen. Thats because the drive is still marked as a raided drive. Here are the steps to clear that.

While in the live DVD/CD open a terminal and run the following

Replacing X with that drive letter corresponds to your drive. Typically and in single drive machines that will be "a", so the command will be: "sudo dmraid -E -r /dev/sda"

It will prompt you...confirm that yes, you wish to remove the dmraid information.

Return to the desktop and proceed to run the linux installer
