How do I verify my burnt installation DVD?


Hi

From my WinXP machine:
I have downloaded SUSE-10.0-EvalDVD-i386-GM.iso and the MD5 sum.
Using MD5 Summer I verified that the ISO was ok

Using Nero 7, I have burnt the image to DVD and used the "verify option". Nero reported everything ok.

I can boot from the DVD and I did a media check, again "no errors".

I then used IsoBuster to create an MD5 from my burnt DVD and it doesn't match the ISO MD5. After some research I gather that the two MD5's might be different (?)

So, how do I verify my burnt DVD against the ISO MD5?
or is there anything else I can do to check that I have burnt the ISO correctly?

Thanks, Ilija

Are you having problems with the DVD?

Not that I know of...that's what I want to check

But before I set-up a dual boot system (XP + SUSE) I want to verify that the ISO burnt correctly. I don't want it to get half way through the installation and then have errors - it may cause problems as I'm not doing a single OS install...

Thanks, Ilija

I guess from what I've read, the nero "verify" may be the only option (which you used). In k3b on linux it looks like there is a way to pad the disc so that the MD5sum's are the same. But it seems windows doesn't really care too much and just check the two files byte for byte...

Thanks again!

I was given a .sh from another thread (posted in wrong forum, see showthread.php?t=416225)

Do I
1. Copy that stuff into gedit and save as .sh
2. Where do I save it? Currently it's in /home/pc/bin

I tried running it in Konsole as su:
linux:/home/pc # copy-raw-cd.sh /dev/dvd | md5sum
bash: /home/pc/bin/copy-raw-cd.sh: Permission denied

Sorry, complete noob

Usually personal scripts and programs are installed in /usr/local/bin. You did right by creating it in gedit and saving it. I hope you saved it as copy-raw-cd.sh instead of just ".sh".

The last thing you have to do is make it an executable script. You do that by chmod +x copy-raw-cd.sh as the owner of the file (or as root). Then to execute it, you do like you did above:
Code:
/usr/local/bin/copy-raw-cd.sh /dev/dvd | md5sum
You might be able to just type copy-raw-cd.sh /dev/dvd | md5sum, but I don't know if /usr/local/bin is in your path. Oh, and you'll probably have to run as root, but I'm not sure....

Me again

Yes, I did save it as copy-raw-cd.sh

I made it executable and then moved it to that folder (had to look up how to do that as well - mv
Ran the script as root using your instructions as above and...it worked!

My MD5 (DVD) from the script matches the MD5 (ISO) - woohoo!

Thanks very much to pljvaldez and gilead for your help - it is most appreciated.

Regards, Ilija
