Description Stuart Ellis 2005-05-15 17:10:51 UTC
Description of problem, bug, incorrect information, or enhancement request:

Anaconda's Media Check will often fail valid discs.  The workaround is to boot
Anaconda with "linux ide=nodma" (which works for me on FC4t3).

This issue has been around for a couple of releases, so there are a number of
bugs filed against it.  #1552266 looks like the most recent of these:

They are all marked as assigned to Dave Jones, so he may be able to give a
clearer picture.

Making a release notes blocker so we don't lose it again.

Comment 2 Karsten Wade 2005-05-31 03:46:28 UTC
Used content just about like this for the final release notes for FC4.  Thanks

The <command>mediacheck</command> function is highly sensitive, and may
report some usable discs as faulty.   This result is often caused by
disc writing software that does not include padding when creating discs
from ISO files.  For best results with the
<command>mediacheck</command>, boot with the option:

linux ide=nodma

Use the <command>sha1sum</command> utility to verify discs before
carrying out an installation.  This test accurately identifies discs
that are not valid or identical to the ISO image files.
