Hi I ve donwloaded suse linux 10.1, 5 iso images.For md5sum i used md5summer to check the hash and it matches perfectly with those provided with the version but whenever i burn those iso images to cd and try to install it shows wrong md5sum, i used both nero and cd Burner xp pro 3 with writing speeds as low as 1x and 2x but still no avail. Am i doing something wrong? plz help.

Did you run some kind of "media check" feature from the installer, or does it provide such a thing? Have you tried installing? If the md5sum doesn't match after the burn it might not mean the discs are trashed. K3b (on Linux) provides an option to check the written data, so it verifies the disc is written all right. I'm not sure how the check is made, but does Nero provide such a thing? Just to make sure the burned data matches the iso image..

I'm not sure that md5summer has the capability to scan a CD in windows for the matching md5sum. You would just be getting the hash of the files on the CD and not including the CD data that you can't easily see like what the image has.

I would imagine that if you did have an installation of linux sitting around somewhere and did a "md5sum /dev/cdrom" it would probably show that it is correct. I would go ahead and try to install with it unless an installer told you it was incorrect.

No, md5summer does not check the cd's for md5sum, that i used to check the iso images on my hard disk drive, and it was the installer that showed md5sum wrong for 3 of the cd's, But anyway folks my problem got solved as it was the troubling RAM, i have two sticks of 256 DDR RAM but somehow they were not compatible with each other, thats why the contents of cd that i burned didnt match those on the hard disk and md5sum didnt come good.
But thanks a lot for all those who replied.

Hm now that I think it, I had "broken" discs once too, some old RedHat installation..they all claimed to be improperly burned (the installer told me), and after I had burned three sets all claiming the same, I just tried and succeeded. Later I got to know all the cds were ok (heh got the idea to try on another computer, but too late)

It's really annoying.
