Ok I installed knoppix to my hard drive..

everything is ok untill I try to boot up I get this error

hda: dma_intr: status=0x51 {DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
hda: dma_intr: status=0x51 {DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
hda: dma_intr: status=0x51 {DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }
hda: dma_intr: status=0x51 {DriveReady SeekComplete Error }
hda: dma_intr: error=0x84 { DriveStatusError BadCRC }

I read on another thread it's because I need to remove A line from the bootmisc.sh file so I booted from the CD and attempted to change this file but it is read only and I cannot change any of the file permissions or anything.. I right clicked the drive and chose change read/write status or something and made the drive writable but it didnt seem to do anything.

So i right clicked the drive again and changed file permissions there to all read/write but that didnt work either...

I tried these commands from another thread

sudo mount /dev/hd?? /mnt/hd??
sudo favorite_editor /mnt/hd??/etc/init.d/bootmisc.sh

But I get the message saying the drive is busy or something.

Also when I boot from the hard drive I notice the drive is mounted as read only there also..

I hope you guys can help
