Hi John,

Apparently, so have I, because I've thought that in the case of iso9660
(as opposed to UDF) formatted discs, "image and ".iso" were the same
thing.

The way I've always burned discs is either:

wodim dev=/dev/sg2 padsize=63s -dao -pad -v -eject myfile.iso

or

growisofs -Z=/dev/sr0=myfile.udf

These *appear* to have given me readable CDs, DVDs and Blu-Rays.

What's the difference between an image and an .iso?

Odd that you know the command line way to do it but would ask this question. Makes me wonder what you think you are missing, or whether you are asking a rhetorical question.

(The difference being whether you copy a file containing the image to a file system on the CD or other target media, or whether you write the image itself onto the media, so that the resulting file system on the media is the file system of the image. Or, the difference between saving a backup copy of the downloaded image and, uhm, say, imprinting the downloaded image onto the CD/USB/whatever. If you're thinking about writing the image to a USB flash drive and thinking, wow, that sure leaves a lot of unused space on the USB, what a waste, you're probably seeing the difference.)
