Re: cdrecord tsize confusion

Yes. you are now asking the system to create and iso containing the iso you

WILL contain additional information not the original directory system.

Anyway, who are you doing all this?

I am trying to get the following two commands to match:

md5sum foo.iso
md5sum /dev/scd0

-T

If it helps, K3B's original MD5SUM matches my
sum from my ISO file.

Also, here is cdrecord K3B's run line:

/usr/bin/cdrecord -v gracetime=2 dev=/dev/scd0 speed=24 \
-dao driveropts=burnfree -eject -data /home/KasRescue/foo.iso

My cdrecord run line:

/usr/bin/cdrecord -v gracetime=2 dev=/dev/scd0 -dao \
driveropts=burnfree -data /home/KasRescue/foo.iso


K3B's "md5sum /dev/scd0" matches both my and K3B's
"md5sum foo.iso". My "md5sum /dev/scd0" does not
match.

-T

p.s. I asked the author of K3B what he was doing
different. He wrote me back:

"Writing an iso image is the most simple task
there is with CD writing. No tricks, nothing
special to consider... Sorry, I have no idea
what could be the problem."

This has to be right under my nose!
