Media check Fedora core 4 Disk 1 Fail

[cphillips]

Sorry for posting so much, but these are seperate issues.

I keep getting Fail when i perform the Media check for disk 1. I burned 2 different disks, so it cant be the disks.

Are there special settings I should be aware of when burning the ISO's?

Thanks!

Did you burn it as an ISO or just as normal data? Your burning software should allow you to burn it as an ISO. It may be labeled "CD Image" in your settings rather than ISO. Search the help menu in the burning software for instructions on how to burn it as an image or ISO.

If that's not the problem, did you check that the SHA1 checksums matched the ISO's? Fedora has instructions on running

sha1sum

against the ISO to see that it matches on their download page [fedora.redhat.com] under the section "Downloading the ISO Images" (about 4/5 of the way through the section).

The official Fedora forum has some additional advice [forums.fedoraforum.org] for problems with the Core 4 media test failures. See if the

linux ide=nodma

suggestion from post 3 and 6 work for you.

Just did a test on my FC4 disk 1 and it failed too. I just burned it the other day and haven't used it. The sha1sum was successful, and the disk boots.

I burned the iso with cdrecord from the command line with no special options.

I tried using linux ide=nodma and it passed.

Sweet! Now I know what to do when I'm ready to upgrade to FC4.

Just found the explanation for the mediacheck problem [fedora.redhat.com]:

The mediacheck 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 mediacheck, boot with the option:
linux ide=nodma

I am having the same problem. I experienced this with FC3 discs. Booting "linux ide=nodma" worked then but not now. I will try burning with padding.

I tried "linux ide=nodma" on my (already installed) system, and it allowed the media test to succeed, but it slowed the hard drive access to a crawl.

On another computer, I retested the discs, they passed, and I successfully installed FC4 (booting with ide=nodma). I subsequently tested the hard drive on the first computer, and it will need replacement.
