[TriLUG] Big problems with a Red Hat 7.2 -> 7.3 upgrade

[Tom Bryan]

Back in May, I pulled the Red Hat 7.3 ISOs off of the LUGs mirror.  I finally 
had the time to try the upgrade today.  

I made it through to the package install.  The installer was happily copying 
packages to my machine when it got to kdebase.  It complained that I was out 
of disk space (I appear to have plenty still), have bad media, or encountered 
a hardware failure.  

Now my system is in a half-upgraded state.  The first CD is possibly a faulty 
burn (mounts fine, how else would I check it?).  I did run md5sum to check 
the ISO images before burning CDs.  I can't seem to access the CD drive now.  
Any suggestions?  How do I procede?  Could it be a hard disk problem?  How 
would I tell?  I've never hit an install problem like this, and I'm not sure 
how to proceed.  

I do have some options here.  I have two other machines in the house (neither 
with a ton of disk space).  I also still have the ISO images on the hard 
drive of the machine that's now half-upgraded.  Any help is greatly 
appreciated!
