  Wow... I didn't expect that many failures, I've not burned disks... in
the last 4 years.  I'm just surprised.

  I would prefer the disks be verified before the event... I feel
terrible telling people about all the great things the disk can do to
have to follow it up with ... "oops, we gave you a dud".  *especially*
when people give us donations.

  I had a few people give us donations at WEF after I gave them disks...
it goes something like:
=3D=3D=3D
them: Oh so these disks are free?!?
me:   Yes they are free, but if you have any money and want to give us a
      donation you can put it in that jar right there... <me points>
them: okay, great.  <they pull out wallet and put in money>
me:   Well if you are going to give a donation, let me trade you for one
      of the better CDs, <me looks for one of Michael Wenk's burned CDs>...
=3D=3D=3D

  I *really* don't want people to be donating to get a disk that can not
work because it's a coaster.  I did randomly test on of the none Mike W,
disks and found it to be a dud... couldn't even mount it as a ISO filesyste=
m.

- Have you considered doing a CD Verify step?
  (either in a cd-rom drive or=20
   on another machine that does not have the burner attached)
  =20
  I would expect this is much more reliable because it does a complete
disk read of all blocks... the disk image could have thousands of
bad blocks and still boot.

- Which cd burning program are you using to make the disks?
