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.

>>md5sum yourcdimage.iso
this can only be run on Linux or windows?

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
