how do I copy the Ubuntu install cdrom via console?
 

After 2 days and 6 possibly ruined CDs I am ready to try to copy my Ubuntu install cdrom by using commands from the console.

I have tried Brasero and K3b with the same failure results. I have a brasero.toc and brasero.toc.bin files on my disk, but brasero.toc will not burn to a cd. As always I am completely lost and frustrated as to why this isn't working.

This should be easy...copy cd ISO image to hard disk, burn ISO image from hard disk to a blank CD. How hard can that be?

Please, no additional GUI cd copier suggestions. I want to learn the commands via console. Thanks in advance.

You could try:
Then you could mount that iso:
Then when you want to burn it:
you may want to adjust the speed etc. if you need to erase before burning add "blank=fast".

Hope this helps'

Just had a thought K3b I think uses cdrecord. I hope it works.

*
K3b : Toolbar : Tools > > "Burn CD Image.."
or "Burn DVD ISO Image.."

.....

Thank you for your responses

Your welcome' hit that thank button' I need one then I can live up to your rep'

Please excuse me; I can't resist.

err, well, so far, it has proved just too hard for you, how hard did it have to be ;)

In spite of this being exactly what you didn't ask for, here is a k3b/gui suggestion; if you don't like what k3b is doing for you, you can always look at the command line that it issued and modify it.

Also, in cases like this, when you don't need archival permanence and things might go wrong, the use of RW media (or DVD-RAM) is indicated.

micxz, a special thanks for the console commands. That is what I will most likely use in the end. Certainly it would be easier to use a GUI based copier, but so far, not good.

knudfl, thanks for your reply.like before, that almost worked:

Thanks again

your welcome' RLIMIT_MEMLOCK part I think is just a warning ('ulimit -a | grep locked' to see your users limit) it's the error part that's stopping your burn. I don't know how to debug that error. I hope you don't have too many "coasters".

That almost worked...but the .iso file gets too big. The original cd is 693 MB, the ISO is 725+ (see below). My CD cannot go over 700.

BUt, it did copy the CD to ISO on /home, and after adjusting write speed it did try to burn to a CD, so that's 2 big steps forward. Just need to get rid of that extra 30 MB and it will probably work fine. Thanks again.

Hum maybe some hard links didn't get translated in the iso format. I'm guessing. You could try to over burn or remove some files you don't need and make the iso agian. I'm not sure how to approach this.

or use a dvd

The cd im trying to clone is the Ubuntu install CD and it fits on 693MB. So, there should be no need to remove any files, and even if I knew which ones aren't necessary, I wouldn't know how to delete files from a CD-R. I can't use a DVD as I only have a cdrw, and don't see a dvd in my near future.

I will try a few more times and then resign myself to not having a backup. At the rate this is going, Ubuntu 9.1 will be out before I get this one cloned anyway. Thanks again

this might be a silly suggestion but you could download the iso from ubuntu's website.

I think that iso files aren`t exact images. I think they contain some extra data, perhaps error correction code. Or maybe I`m thinking of some other image format.
Personally, I use 700MB CD-R. I wish I could use my 650MB CD-RW but that is impossible.

- Someone Awesome has got a point here get a fresh iso.
- I believe there are bigger cdr;s available (800MB) I don't know how reliable they are.
- You can't delete from the cd but you can copy the files/folders remove stuff you don't want and make an iso with mkisofs I wouldn't suggest this unless you know what's what'

Does anyone know why an iso would be bigger than the cd it came from?
