You can mount the iso images to a loop device before you burn them so you can test them.

From a prompt do this:

mount -o loop /cdimage/cdimagename.iso /mnt/mountpoint

Then, you can:

cd /mnt/mountpoint

Your CD IMage will then be mounted in that folder as if it were mounted from a CD-Device.

BUT, before you even get to all that, MD5SUM is your bestest friend.

Most CD-Images you download from the net will be distributed alongside an MD5SUM (checksum). It's usually a separate txt file that simply contains a long hexadecimal number sequence.

Simply download that file and open it in a text editor.

Then run: md5sum yourcdimage.iso
Now compare the output with the numbers in the text file. ( tip, you don't have to sit there and compare each and every number, usually, if the first 4 and the last 4 digits match, the ISO you downloaded will be 100%

If they don't match, then your doanlowd was not successful.

If they match, and you have problems with the burned disks, you either have faulty media, or you cd-writer device is faulty.

You can run that particular command only on Linux, however, there are many MD5SUM checking tools for Windows. On Windows I use "FastSum", just google for md5sum checkers
