The initial problem was that you had an image BUT it wouldn't burn with
k3b. My suggestion was to use the command above WITH the image that
wouldn't burn with k3b to see what the result was.

So this is a different image which you have just now created to try out
the above command, and you are not sure if you created it properly?

So now you have added another variable to the equation. Complicates
things, and who knows, this change alone might fix your original
problem. Note: I have no idea whether this is the case, but the act of
taking the drives out etc, may have some affect depending on what is
causing the problem.

Try with a good iso image, a netinst or similar should do. Try again
with *that* known good image and with out any multi mumbo jumbo.

Unfortunately, that is one of the side effects with problems such as
this. It is also a problem with printer problems. :(
I think there is a dry run option with wodim.

Yes, but the disk is crook right? So anything else won't magically fix
it, despite what the program says.

I read it as the drive doesn't like the disk or the image.
"Sense Key: 0x4 Hardware Error, Segment 0" and "logical unit
communication crc error" with "Sense flags: Blk 0 (not valid)"
Try burning a netinst image on to a new CDR disk with the command:
wodim -v speed=2 dev=/dev/hda xxxx.iso
where xxxx.iso is the netinst image you download from the Debian site.
