Lately, when trying to boot from the Knoppix 4.0.1.iso on my hd , I get an error message ACCESSING KNOPPIX CD FAILED, UNABLE TO MOUNT. It continues to boot to the desktop, but then I'm not allowed to eject the cd. I've also gotten a second error message during boot, asking if the partition is encrypted, which it is not. Booting from the disk itself works okay, so that problem is apparently something in my hd. Any thoughts? <ADDED 3/16/07> Never did figure this out, but I am now running 5.1.0. CD and it's working just fine.
