Folks,
As much as I hate to, I feel I need to post my long story and ask help.
Shortly after the release announcement, I kicked off rtorrent and downloaded the CD and DVD images. Since my cable provider does my "throttling", I disabled throttling and shared for several days, "returning" several GBs at no objectionable loss I could discern.
While that was going on, I used cdrecord (don't jump to conclusions here, read on) via CLI to burn the CDs. This on a fully-up-to-date CentOS... well here
uname -a Linux centos01.homegroannetworking 2.6.9-42.0.10.EL #1 Tue Feb 27 09:24:42 EST 2007 i686 athlon i386 GNU/Linux $ lsb_release -a LSB Version: :core-3.0-ia32:core-3.0-noarch:graphics-3.0- ia32:graphics-3.0-noarch Distributor ID: CentOS Description: CentOS release 4.4 (Final) Release: 4.4 Codename: FinalCD writer is a generic 52x24x52x that I have used to burn many CDs before w/o problems. On this unit and the other I'll mention, the writer is master on IDE channel 2. Neither has an HD on that channel currently. The other unit has SATA drives and the writer is again on IDE 2 by itself.
Disc 1 passes media check and 2 - 6 fail consistently. Checks OK:
...CentOS-5.0-Old]$ md5sum -c md5sum.txt CentOS-5.0-i386-bin-1of6.iso: OK CentOS-5.0-i386-bin-2of6.iso: OK CentOS-5.0-i386-bin-3of6.iso: OK CentOS-5.0-i386-bin-4of6.iso: OK CentOS-5.0-i386-bin-5of6.iso: OK CentOS-5.0-i386-bin-6of6.iso: OK CentOS-5.0-i386-bin-DVD.iso: OKIIRC, I also used the sha1 check (can't recall the command ATM) and it also passed.
At one time I got media check errors on a particular DVD in a new drive sometimes but not others.
My solution? Don't do the media check, that way it can't fail:-) If the install works, who cares what media check says?
Why not burn boot.iso and do an NFS install? You don't need to burn the rest at all.
My 2c ; Ditto (or similar?) - Memorex DVD writer with the CentOS5 dvd - md5sum says the iso is fine, but even burning at the lowest speed it would not pass the Nero "verify", however the install was flawless. Maybe i had 3 bad dvds in a row, but unlikely. Maybe it didnt write well, but the damaged data was in packages i did not install? Fairly likely. Bottom line is that the md5 passed (good iso image) and the DVD install worked.
