    Any success installing DVD to HD?

    I have tried all three options to install to hd and many errors encountered. When the installer finishes, it states success and I reboot into a kernel panic. Anyone had any success?

    Are we talking 4.0? Sounds like your burn didn't go well. Did you do a MD5 check? I downloaded 4.0 a couple of weeks ago and have now installed it on 7 HD's. There is sort of an urban legend about writing the DVD at the slowest rate possible.

    There is sort of an urban legend about writing the DVD at the slowest rate possible.
    I have had many issues with discs burned at high speeds. Especially Audio CDs. They will not work in many CD players unless I burn them at a slow rate. This is more evident in the car or portable players. Also, some DVD Videos have had "Compatibility" issues with some players unless they have been burned at slower speeds.

    Here is my simplified theory on the issue. To write a disc, especially a RW disc, the laser "Burns" a "pit" into the disc. If the pits are well defined and accurately placed, they can be read accurately. As the disc rotates faster, the amount of time the laser has to make a well defined mark, during the burning process, is shortened substantially. In short, the laser has difficulty making well defined pits in a shorter amount of time. That causes read errors, especially on RW media, since it is more difficult to make a well defined pit on the RW disc. Some media is more laser sensitive than others and some drives are better regulated for laser intensity on various media. That allows some drives to write on certain media at higher speeds. The obvious solution to the issue is to burn the discs at a slower speed to ensure that the pits are well defined and accurately placed, and not take the chance that their combination of drive and media are well matched for higher speeds.

    Now the other side of the equation. The drives that are used to read the discs can have issues reading those pits as well. Some drives are better at reading poorly defined or placed pits than others. That explains why some drives are better at reading a disc that some others have failed to read or recognize.

    Sometmes a firmware update can help eliminate some of these issues on the burn side or the read side of the equation and sometimes both.

    There are other parts to the puzzle, such as media dye types and colors, recording layer reflectivity, etc., but that is my basic theory of why a disc should be burned at a slower rate for best results and compatibility.

    Yes version 4.01. I ran a md5 with K3B and checked fine. I now installed 3.9 no problem.
    I think it might have been the fact that I had installed a new harddrive as a slave to my burner.
    Then I noticed that the boot sequence tried to detect my dvdrw as a hardrive and could not synchronize with it. I just changed the bios for my dvdrw to auto and removed the secondary slave hard drive. I will try it again. Keep you posted as to what happens.

    We have cautioned new users from installing Knoppix to the HD without first being aware that it might not work for them http://www.knoppix.net/wiki/Hd_Install_HowTo. You may have run into a known issue with Knoppix 3.9 HD Installs in that it breaks networking.

    The bug is documented as #15 http://www.knoppix.net/wiki/Bugs/3.9-2005-05-27 and can be resolved by entering the command as root user:
    ln -s /etc/init.d/ifupdown-clean /etc/rcS.d/S18ifupdown-clean

    Version 3.9 seems to be fully functional. My networking is fine. I'm a bit hesitant about trying 4.01 again, 3.9 seems to meet all my needs. Now I'll attempt to install vmware by reconfiguring the kernel from the source. I imagine that rpms in Knoppix will convert to .Deb with alien. Will try this now.

    Errors encountered while installing 4.0 to hdd.....

    Hello all,

    As whitehat stated, to have tried all the three options to install 4.01 to hdd: I've also not been able to get it done, also tried all the three options.
    In oposit to the newly build suse-linux, with gnu and kde, which installs perfectly.
    The kdee taskbar has the function to resize, which makes it look smoother, but its, compared with knoppix 4.01: to 'naked' for me. So, isn't there anybody who can write an installer that works?

    Well, I've had no problems (knock on wood) with getting DVD 4.01 installed and running from my HD. Only weirdness I've seen so far is the tendancy after a reboot for my wireless to sometimes show up as eth1 and sometimes as eth2. I didn't have this problem with the 4.0DVD, but that version still has the UB module, and I use several USB external drives. So many I had to do some mknod stuff today to deal with the USB drives now being /dev/sd rather than /dev/ub.

    Process I followed was to boot the DVD, then use sudo to create a root passwd, then an su - to become root, and then run the "knoppix-installer" script. Prefer to run that as root to minimize any permissions issues.

    FWIW,
    Ewan

    I got the same Kernel panic problem with the 4.02 CD HD install, I will try another download.
    Btw just a note from my friend who worked in a CD factory, he said there is some code marked at the inner track about the max writing speed of the disc for the burner to read, but some off brand disc intentionally marked with higher than useable writing speed, so the disc can be sold at higher price, but will be burnt with error at that speed. The coating of the disc must be of high quality in order to receive enough lazer engry when burn at high speed, because the lazer pulse will be very short, so burning at lower speed is always safe.
