KNOPPIX 5.3.1 Error:

Accessing KNOPPIX DVE at /dev/sr0 ... INS mod/ '/cdrom/KNOPPIX/modules/cloop.ko' : Input/Output Error
Can't find KNOPPIX file system, sorry

I've burned two cd's and two dvd's, lowest possible speed ... both have several files that won't open ... says files may be corrupt.

Can't open /cloop.ko ... says its corrupt

The correct cd is being read, but the files are corrupt.

Tried to mb5summary thing, but it doesn't list the iso files, so can't check 'em.

Jzip won't open several files, including /cloop.ko ... jZip says they are corrupt.

Traced it back to the downloads ... any idea where to download a good copy?

What do you mean that you can't check the md5? Every single md5 test program that I've used (and I've tried several) can check an ISO file just fine. The FAQ lists several choices that all work. Perhaps you should post exactly what program that you are trying to check the md5 with and what steps you are taking to get to the point where you think the file can't be checked.

This certainly seems to be the problem. In fact, I would bet money that it is the problem if you ignored the advice to use BitTorrent and instead used the mirrors, which are well know to have corruption issues when downloading to Windows systems. I can assure you that within just a few minutes you can get a program to do the md5 test, run the test, and know for certain if you have bad ISO files or if you are doing something else wrong (although you may have bad md5s and still be doing something else wrong).

Jzip won't open several files, including /cloop.ko ... jZip says they are corrupt.....
Again, awful good chance that the ISO is corrupt, but what are you trying to do with Jzip? You certainly should not be trying to unpack the ISO file. Just check the md5 and, on the slight chance that it turns out to be OK, burn the ISO to a disc as an image.

MD5summer v1.2.0.11
Windows MD5 - Sum Generator

http://www.md5summer.org

I'm probably not using it correctly then. So I'm an idiot.

I thought I'd like to try this KNOPPIX thing, but it may be beyond me.

So say ... I want to burn an image cd ... where would I download it and how would I conduct error checking on the download to ensure its correct?

Easy now ... put it in layman's terms (baby steps).
Since you were stressing that you had burnt at low speed, I had thought that you had already read the downloading faq. But if not, follow the documentation link near the top of this page to find the wiki, and read the downloading faq (there should be a link on the main page that get you to it). This will answer you questions about how to download (stressing BitTorrent) and various programs to check the md5.

md5summer is fine for checking the ISO. User interface isn't perfect, but I've seen worse. Not sure why, but programmers who do md5 code seem to shy away from the normal Windows "standards". To check the md5 you should have a file that already contains the actual known md5 value for the file or file in question. With md5summer there are two options:

1) if the file that you have ends in .md5 then put it in the same directory as the ISO file and start md5summer. Then navigate to that folder in md5summer and select the "verify sums" button at the bottom, check the ISO (and/or any other file listed in the .md5 file). As a way to simplify this, if you associate the md5 extension with md5summer or use the "open with" option and select md5summer, you can just click on the .md5 file and md5summer will start and begin the md5 calculation.

2)if the file that you have does not have an md5 extension but rather a .txt extension or some other extension, then it might not be in the exact form that md5summer needs to use. However, it will be a text file that you can open in any editor, such as notepad. (An md5 file is actually a text file, so you could use this approach with an md5 file too.) In this case, open md5summer and navigate to the folder that the ISO is in. Click the "create sums" button at the bottom of the page. Another window will open that shows all of the files in the folder. Click on the ISO file and then push the "Add" button. Then click OK. The MD5 wiil be calculated, and another window will then open to let you save the value as an md5 file. You might as well save the value, but you can see it and write it down in the window already open. It will be a string of 32 hexadecimal characters. Manually compare this string to the pre-calculated md5 checksum that you downloaded. If they match then the file is exactly the same as what was originally posted. If they don't then the file is corrupt and burning it to disc will result in a coaster.

3) if you don't have a downloaded md5 file to do this test against then there is no point in computing a md5 file for your ISO. I did say that there were two options, not 3.

The Get Knoppix link near the top of this page will give you a link to the torrents for Knoppix. When your current ISO turns out to be corrupt, consider installing any of the popular bittorrent clients, configure your router to allow the bittorrent ports to reach your computer (you are using a router, are you not?), and then download one of the small torrent files and use that to have your torrent client get you the Knoppix package (which includes the ISO, an md5 file and a few other handy files). If you want an English version of Knoppix, be sure to get a version with EN in the name, not DE.

Thanks for the info ... I've got bittorrent downloading ... downloaded a little last night, finishing now.

I'm nervous about the seeding and sharing stuff ... goes against what little I know about security ... but I'm doing it.

Will post again with results.

Again ... thanks.

BitTorrent 6.1.2 is at 70% downloaded for KNOPPIX_V5.3.1DVD-2008-03-26-EN, however, I've got the following Logger entries:

Should I continue with the download? Will this self correct? Hate to waste more time waiting on something that will tell me this failed.

I edited this post to include anoother (not sure if its the last) logger message.

Can anyone tell me if this download is usable? I don't want to burn another cd to find out this doesn't work. I'll run the md5summer on it to see what it says ... but again, is that even worth it with the error messages saying that certain 'pieces' are suspect?

Can't answer this on my own ... don't know even about it.

Edited again ... ran all the downloaded files through md5summer and all are green (ok) ... so I'm going to risk a disc ... should I burn the dvd version to a dvd or a cd? I thought I read an earlier post to burn it to a cd ... at slow speed ... so that is what I'll do.

Well I didn't do it ... I burned the image at Auto (max) speed and the burn failed:

Looks like this one burned ok ... 4x, Maxell DVD-R 4.7 GB 16X.

There have been some bogus, infested "I'm better than the real BitTorrent" clients, but BitTorrent itself is safe. You only share the torrent that you are downloading (or explicitly hosting after the download if you choose to). Your other files are perfectly safe.

The download and image burn seemed to work ... My system is booting with the dvd in the tray ... but ...

Now I'm getting and error: No suitable X server found for your card.

I read somewhere about Nvidia drivers ... I'll do look and see what I come up with.

BT does it's own checking on the parts of the files as it gets them, if any part isn't perfect it discards it and gets another copy from somewhere else. Thus the errors you saw logged. No a problem, just an indication that BT is doing what it was designed to do. If BT finishes the download you have good copies.

The md5 test isn't needed as much after a BT download, but you have the files and it's a reasonable recheck to do. I did see one case where someone stopped BT as soon as the indicator hit 00% but before BT was really done, andf he did have a bad copy that the md5 would detect. Another nice thing about BT is that in such a case you can just restart BT, it will take a few minutes to check what you have, and then it will quickly fix the download by getting the missing parts.

Low speed burning of the ISO is pretty important for a reliable boot. Absolutely important is making sure that you burn the ISO as an image, lots of people just try to copy the ISO to a disc or extract files from the ISO or take some option to make the disc "bootable" or make some other choice that conflicts with this part of the instructions. I don't know what burning software that you are using so can't be more specific, but this is all covered in detail in the downloading faq.

Since you now seem to have md5summer working, can we assume that your previous ISO downloads were determined to be bad?

You're getting closer. Don't try to get specific Nvidia drivers. Boot the disc and at the boot prompt type
knoppix xmodule=vesa
and see if that does the trick. If not, read the cheatcodes.txt files that came along with the torrent download for other codes that might help.

Yes ... I would make that assumption ... but I can't verify it as I have deleted the old downloads.
