questions on downloading ISO's and burning CD's


2 questions really:
1) The download section of this site talks about comparing the MD5 checksum from your download and compare it against the checksum on the website you are downloading from. The problem I'm finding is that there is no MD5 checksums listed on the ftp sites that I am using to download ubuntu. Is there a specific place I should look or another way to verify my download is good?
2) Also, I keep getting write errors when I try to copy the ISO image to disk using Nero. There's a section on this site on Nero, but I have searched it, the Nero help file, and the Nero website and cannot find the problem. Is this a bad download or something else?

There is usually a file on the Ubuntu FTP mirrors called MD5SUMS. In there. you can find the checksums.
In Nero, you should choose the option to "burn the image to disk" - not "create a new data disk". Don't remember the exact labels, but that's the idea. Though I am not sure, I believe that Nero can calculate the checksum - otherwise, you can find a program for it here.

OK, I found the checksum and verified that my download is correct. I am still having problems writing the image to disk. I use the "burn image" function and get the following:

Any idea what I need to do to fix this?

I don't know what the issue is with your NERO, but I have seen many people in the newbie forum have problems burning image files with it. I suggest a different burning application, like Alcohol 120%. This is what I have always used, and I have never had any issues with it. Or you could use a program like ISO Buster or Super ISO. I know its not that easy to just grab software, but you could see if they have a trial, or just steal them via Bittorrent likeone of my friends did.

Seeing as everybody has been so gracious in helping me on this. I thought that I should post my latest discovery/solution.
I downloaded Alex Fineman's ISO recorder and tried it and it failed also. The problem appears to be my using CD-RW media. Apparently this does not work well with ISO images. Once I used a standard CD-R disc it worked fine. Of the 3 CD-RW discs I used in my attempts to copy the ISO, 2 are completely shot, my drive simply won't read them. The third, interestingly enough did copy at least the folders located at the root, even though all my attempts to copy the ISO gave me ugly error messages from whatever software I used and some of the stats that Win explorer gives for the contents of the one CD-RW that is still readable make me suspicious of its contents.
Anyhow, the bottom line here appears to be don't use CD-RW discs for ISOs.

Mike
