FC4 Test 1 CDs fail mediacheck

[jermyandhisbass]

I downloaded the four ISOs name FC4-test1-discX.iso.  The SHA1 sum on
each of these checked out fine, so I went ahead and burnt these to
CDs.  Upon booting from CD1 and running the mediacheck, the CD fails. 
I also attempted to run the mediacheck using VMWare,  emulating the
CD-ROM from the ISOs, upon which the mediacheck failed as well.

When attempting to install, I can get all the way to the "Installing
Packages" screen when I receive the message "An error occurred trying
to format hda2. This problem is serious, and the install cannot
continue. Press <enter> to reboot your system."

Checking the logs shows that it is failing while attempting to format
/.  Any help?
