I installed Knoppix 4.0 for a friend and it looks like the CD was badly connected at the time of install (wrong jumpers set). Somehow (however) the install ran through fine and everything (apart from the CD is working fine).

Now I am trying to clear the problem but find that I cannot get the system to talk to the CD:

I can see the CD declared at boot (Knoppix script) and I can see the cd (/dev/hdc) when I open qtparted but the CD doesn't appear in BIOS settings and also is not available from KDE:

When I click on the standard CD icon I get the message:

"Commnd not available: The file or directory file:///mnt/cdrom does not exist"

But when I look in /mnt/cdrom I see a shortcut with the properties saying it points to: /mnt/auto/cdrom ... which seems normal.

I then tried to create a new icon and found that a device /dev/cdrom (/cdrom) was available for selection. However, after creating the icon then, when I tried to open the device I got the following:

"Drive couldn't be attached. The error was: mount: /dev/cdrom is not a valid block- orietated device"

Does anyone have an idea for me here? Indeed, I believe that during installation, I confused the system and now, even though the CD is now available, it is having trouble linking it in.

But I believe that there must be a script that I can change to get the system to talk to the CD.

Any tips would be a great help for me as I am not sure whether I should correct this in the BIOS or in Knoppix/Debian. Or whether I should check to see if any connections/settings are (still) wrong (but I don't think so).

I just hope that I don't have to re-install.

Many thanks for any tips that you can give me.
