Knoppix isn't detecting my HD

I posted awhile ago because i was getting Cfdisk error and Knoppix wouldn't detect my HD.

Still having that problem. i also can't create a persistent hardrive.

anyone know how to solve this.

I was using mandrake but in my partition adjustments I can't get that to work. All i have now is knoppix live.

I really really want to use knoppix as my permenent OS, but It's been three weeks and I can't figure out how to install (though i am a moron-newbie)

any help would be apprecoated. thank you.

You can't run cfdisk unless you are root. Otherwise we'd have users deleting partitions left and right! So do this:

sudo cfdisk /dev/hda

(Of course I assume you have only one hard drive.)

When i do that I get a message that says : Fatal Error cannot read disk drive, press any button to exit cfdisk.

What is going on?
