Hi Vince,

I cut CD and that CD is letting me run hardware test now.
I think I will let it run the memory test all night long and
catch some sleep myself and boot ubuntu tomorrow.

What you told me is indeed a fantastic operational wisdom.
But I still don't understand why bunch of files cannot be put
onto different media.  If I have a directory full of data, and
I can transport it on a floppy, tape, memory stick, or whatever.
So long as I have a compatible device to read the data, media
doesn't matter, does it?

I thank you very much.

Huuu, here, I only meant that the terminology calls it an ISO
"image" (rather than "file") for a good reason ! ;-)

Well it's jsut how things are. A CD image is a CD image and a DVD image
is a DVD image... triyng to fit a sqaure in a round is not going to
work is it ?! ;-) I can understand that the fact tha ta DVD and a CD
medium are visually a similarly sied piece of round plastic, however in
the inside, a DVD is not a CD... hence why you (used to) require a
different optical drive to write a CD or a DVD.
When you had 3.5" and 5.25" floppy disks, you would not try to stuff a
3.5 disk into a 5.25" drive... same for a Cd and DVD... two different
