I hope this may help others who encounter the media test failure and 
'Assertion (heads >0)' bug during an upgrade of FC2 to FC3.

The workaround which definitely works (The workaround on the RH site 
doesn't!) is to boot from your FC2 CD1 and run the media test from 
there. Once the media check is completed then Ctl +Alt + Del to re-boot 
the machine and start the upgrade again.

When the 'Assertion (heads >0)' bug bites after selecting the keyboard 
just keep banging away on the 'Cancel' button and the upgrade will 
continue. The same bug will bite again a little later, just keep banging 
away on the 'Cancel' button until the upgrade continues and all will be OK.

According to bugzilla it is resolved but, probably due to my ignorance, 
I could not find what the resolution was. HOWEVER.... the bug is caused 
by the bug-ridden version of PARTED v1.6.15 that comes on the FC3 CDs. ( 
run PARTED 1.6.15 from the command line as root and you will see what I 
mean). I would imagine, but I haven't tried it, that if you install the 
latest version of PARTED before doing the upgrade to FC3 then IF PARTED 
is run from the HD and not the install FC3 CD1 (I haven't found the 
PARTED executable on the FC3 CD1) then the bug will not occur

Hope this helps others.
