Need help creating CDs that will pass mediacheck

[Dan Trobridge]

New to Fedora, but not RH.

Pulled binary ISO's using torrent and all passed md5sum.
I have created several copies of the ISO's using Nero 6 and have tried
several different combos to burn.  According to what i have read it
should be as simple as <Record-Burn Image-(Select Image)-Check
Finalize CD-Burn.  None have past linux mediacheck yet.
disc1 fails with "...glibc-common-2.3.3-74 cannot be found."

I have 5 disc1s randomly pulled from the spindle,  all which fail. 
None of the other disc's I have created for Fedora have passed the
mediacheck either.

Thanks for the help.

Try burning them at a lower speed maybe 2. Sometimes cd media prove difficult
to burn correctly at higher speeds.

While I don't recall ever seeing that particular message, many good
discs fail the media check [known issue].  Go figure. I'd try installing
from the 'suspect' cds. If you have really burned .iso images [and not
copies], I bet they work.  Esp if you used bittorrent :)

YMMV,

[Craig Thomas]

I should add that if they don't work, and writing new ones at slower
speeds doesn't sound good or doesn't work, you can install using other
methods [http/ftp/nfs].

[very valid and very useful set of docs IMHO]

[Dan Trobridge]

Thanks for the input.  I tried the slower speeds, but sadly it didn't
work.  Instead I got "cpio: Bad Magic" error when trying to install. 
A new challange to resolve.   I want to prove that this burner I just
got is capable of making these discs.  If I have to give up on the
discs I will move on to that other doc.  Thanks for passing it along. 
I am downloading, by Torrent again even though the md5sum was good. 
Don't really know what else to try  Just 19 more hours and I will have
a fresh copy.

Could be the media perhaps?

Have you tried to make the iso from the burned CD (that you burned from 
the original iso) and checked the MD5SUM, again?

Cheers,

Have you tried verifying the burned image? I don't know about Nero, but
most burning software has that option. If what's on the CD matches the
image on disk and your MD5SUMs check out, then that should give you an
accurate CD.

This problem seems like the one overcome with either booting with
linux ide=nodma
or with the other option to just disable dma for the CDROM drives.
The problem was with the 2.6 kernel compared to the 2.4 kernel. Anyway, 
the disk most likely was burned correctly and in a usable state.

This problem was discussed when people were hsving it when FC3 was first 
released. The archives should give you more information regarding this 
problem.

The burned image was put back to the harddisk and md5sum run against
it again.  The numbers matched.  I think this implies that everything
should be fine yet the install keeps stopping on the
glibc-common-2.3.3-74 cannot be found error.

Read Jim's post on this.

nodma option is very often VITAL to proper installation.

Too often probably, but then there are so many IDE controllers out there 
which don't necessarily 100% conform I guess we can't blame the software.

Strongly suggest trying this especially if you're running VIA or SIS 
chipsets. I've never really found a problem with Intel, but others may have.

Ed.

Make sure you burn them using DAO and not track by track.  I don't know why 
but that fixed the problem for me.

You may also need to slow down the burn speed (try 4x or something
along those lines).  Make sure you use 700MB media, not the 650MB
stuff and use name-brand media (TDK, Maxell, etc.).

Thanks for the help everyone.  Still no resolution.  I have been able
to get disc1 to pass media check, but no others.  I was able to
upgrade one pc from RH9 to Fedora.  The PC which I wanted Fedora on
still will not take it.  I guess I am looking at a hardware problem
now.  The PC in question did take RH9, but no upgrade.

I can't say that this thread is solved as I still have not been able
to create a collection of discs that pass mediacheck...  On the other
hand I am running Fedora 3 on one machine and the other may have some
hardware issue with Fedora that it does not have with RH9.

For the record I have:
regrabbed, by torrent FC3.
Confirmed md5sum
burnt slowly(8x as slow as it would go and DAO)
Recomfirmed md5sum of ISO on cd
Past mediacheck on disc1 failed on all others
Tryed to install using: 
linux mediacheck nocddma
and
linux ide=nodma

At this point I have to assume that the CDs are good enough and move
on to hardware issue.  Install works on one machine and fails on
another.

If you have multiple CDs, and they are networked, you should look at
trying a network install: I find that they can be much more reliable.
Boot with CD1 and type linux askmethod at the very first prompt, or use
one of images/boot.iso or images/diskboot.img.

Also consider doing minimal installs (less to go wrong) and installing
anything else you need afterwards.

Incidentally, would you mind trimming your messages down? Leave out
stuff that you've been quoting, but you aren't replying to.

Hope this helps,

James.

I suspect that you are having another manifestation of the problem I just
posted:
  https://www.redhat.com/archives/fedora-list/2005-March/msg02774.html

I have hit this problem in several different ways with 2.6 kernels.
Grrr.

Here's a crude solution that has worked for me: pad the .iso by adding
a bunch of bytes at the end.  Those bytes won't influence the ISO-9660
file system, but will allow the goofy device driver to read ahead past
the end of the file system without getting an I/O error.

How much padding?  I used a couple of megabytes of zeros, if I
remember correctly, but I now think that I know the magic minimum
number:  33 * 2k.  This is the length of the reads that were failing
(see my previous message) so it ought to be a bound on the amount of
spurious readahead.  It might be the case that the 33 can very under
some conditions -- I don't know where it comes from and I'm too lazy
to read the driver code at the moment.

How can you pad the .iso?

Method 1 (untested):
    dd if=/dev/zero bs=2048 count=33 >>file.iso

Method 2 (untested):
    When burning with cdrecord, add the parameter:
    	padsize=33s
    (I don't actually know if a sector, in cdrecord's terminology
    is 2048 bytes; the manpage suggests so.)

I find it interesting the the cdrecord(1) manpage, in its description
of the padsize option, says:

Use this option if your CD-drive is not able to read the last
    sectors of a track or if you want to be able to read the CD on a
    Linux system with the ISO-9660 filesystem read ahead bug.

If you do test this, please report back whether it worked or not.
Please cc it to me personally since I don't read this list regularly.
