Hi all,
I am trying to install 64bit version of opensuse 11, but it seems to freeze when the installation system checks for packages configuration
I fear that the downloaded iso or the burned DVD are corrupted.
How can I check the md5 of the burned DVD?
Thanks
Valerio
I check it before burning .
Afterwards I a perform a media check
dobby9
From suse: YaST > Software > Media check
From Windows: there are many utilities. Google 
And, yes, it would look like bad media (or picky reader). Always burn an OS cd/dvd at the slowest speed available to minimize errors.

open a console, then
md5sum nameof.iso
Compare with the value you found on the web. I write ISOs with K3B most of the time; it calculates the md5 sum when it reads the ISO.

Don’t forget to read our suse-11 pre-installation instructions, where information on checking the md5sum, and other important installation information is contained:
NEWBIES - Suse-11.0 Pre-installation – PLEASE READ - openSUSE Forums
Thank you all, I use quite always to check the md5sum of the downloaded iso 
What I should want to do is to check if the iso is burned on the DVD correctly: but I understand that the only way is to make the burning software to verify the disk when finished.
Thanks a lot

You can also run the self-check in the installer of the DVD. But that of course requires you to boot up with the DVD.

No, there are other ways to verify the media… in fact the same way
the burners do. You read in the bits from the media directly and then
use md5sum for those. Check out the ‘dd’ command for info. A sample
could be:
dd =/dev/cdrom | md5sum
Now sometimes things are a bit strange and dd reads more data than it
should, so you can tell it exactly how many bytes to read, which should
be the number of bytes you burned from the ISO… so, with a
104857600-byte ISO you could read in 1K chunks at a time, get
100,000-ish of them, and that would look like the following:
dd ibs=1024 count=102400 if=/dev/cdrom | md5sum
In theory the md5sum from the media, assuming you pull in the same
number of bytes as the ISO had, and do so from the beginning, should
match. You’ll notice this operation takes some time… give it some.
Good luck.

The number of 2048-byte blocks to read can be obtained from the header of the ISO file with:
isoinfo -i /dev/sr0 -d
Assuming the DVD is in sr0.
One could even write a script to do this and calculate the md5sum by reading the disk as ab showed.
Did I have invisibility cloak on when I said: “From suse: YaST > Software > Media check” ?

Hi all,
After checking the download with md5sum, I would like to burn the ISO image.
I’m using windows XP with:
Roxio Creator DE
Version: 9.1.573 SP1
I have several options for burning the image and don’t know which to use. Choices are:
ISO + Joliet (106 character file names)
ISO + Joliet +UDF (106 character file names)
ISO Level 2 (212 character file names)
Your help would be appreciated.
Thanks
None of the above.
Look else where for burning as an image file.
Ah, so that’s what you see whenever I post… uhm, I have to investigate… wait, what am I doing typing if all you’ll see is a dot?
oops … so I was careless … forgot to apply a custom colour! Lets try again:
…
Post? I see no post! Do you see a post? Where?
But in seriousness … sometimes users just do not want to click on a link, even though it lays out the answer to their question quite clearly. … I find it frustrating, as it often takes me time to find a link, and then after finding it, after pasting it, the users simply ignore the link … >:(
