Hi All,
I've downloaded this image (disk 2) from several sites, and it matches the MD5 sum. Burning it to a CD gives no errors, but the disk is failing the self-check at the start, and if I ignore that and try to install I get random packages which "cannot be read". I know the burner is OK, as I've burned other CDs on it just fine after burning the CentOS ones. Any thoughts?

I recently had the same problem. The package checksums and everything else turned out to be good and we figured the problem was with the original RHEL install/upgrade process.
I did manage to Centos 3.3 working by installing 3.1 and then using yum to upgrade, but it does make me nervous.

Geoff where did you get this information? I'd be interesting in reading it.
Typically, these issues are: 1) cheap/low quality media, 2) burning at 48X and hoping that old 4x IDE cdrom will read the disk while trying to install.
As a test, turn around and mount mount the CD on the machine that burned the disk and try doing a "cp -a" off the cd to your hard disk.
A better option, particularly if you have enough machines is to setup a machine as a install server. Over the lan it's much faster than CD (for me any YMMV). This box can also be turned into a local repository for yum updates. It's also much faster doing an upgrade off a local box. :)

Typically, these issues are:
- cheap/low quality media,
Multiple disks burned, using various brands. Only disk2 fails, others are fine. Every time.
- burning at 48X and hoping that old 4x IDE cdrom will read the disk
while trying to install.
Burned at 4x, read in a 52x drive that is less than 6 months old.
As a test, turn around and mount mount the CD on the machine that burned the disk and try doing a "cp -a" off the cd to your hard disk.
I will try that.

I'm building from scratch. It's not an upgrade. Still may be a better way though. Can you still install over HTTP?

Yes. HTTP installs are possible. Probably the best way.
I'm planning on putting together a centos howto that covers this sometime in the near future. Bad media is a common issue.
What Redhat issue with disk two are you referring too?
Thanks,

Hi there,
Downloaded & burned disc 2 for the 3rd time on 3 different CD burners and still it doesn't pass the media test but disk 1 and 3 no problems.

Luis,
I have exactly the same experience. On multiple burners, with multiple brands of CDR, at very low speeds. Always disk2. I think the online image is hosed...
