Bad CRC error and readable only bootmisc.sh- Please help!

[Knoppax]

Greetz to all!
I have the following (common?)problem:
I installed Knoppix from the CD,chose Linux from lilo and became after a proper bootsequence the following error message:

Cleaning: /tmp /var/lock /var/run
blk: queue c0334b60, limit 4095MB (0xfffffffff)
blk: queue c0334ca8, limit 4095MB (0xfffffffff)
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 }

You might know this error.
I think I have to edit the bootmisc.sh, but when I boot from the Knoppix CD again and want to edit the bootmisc it is readable only. If i try to open it in the rootshell I get the message that the file is readable only!

What shall I do?

Open the console window after you boot the CD and use sudo in front of the commands then you can edit and save the changes.

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

Replace the ?? with the drive letter and partition needed to be mounted for the editing. BTW if you do not know you are looking for it is the line starting with hdparm near the bottom of the file and you need to put # character in front of the line or delete it.

Now I got another prob. When I enter the command : sudo mount /dev/hda6/mnt/hda6
I got this error message: Can't find /dev/hda6/mnt/hda6 in /etc/fstab or /etd/mstab
What shall I do now?

You need a space between the /dev/hda6 and the /mnt/hda6.
