I have DVD-R that contains a single iso file

The file is clearly present when I use k3b.

But when I use Dolphin the disk appears not to exist.

How can I view the iso file using Dolphin?

First, when you say "when I use Dolphin the disk appears not to exist", are you attempting to open the disk as a Video DVD or similar? Or as a regular data drive/volume? If the former, that's not surprising (see below); but if the latter, it SHOULD show you the file, just as it would on any other media (such as in a folder on your hard disk).

Second, an .ISO file is, by definition, a byte-by-byte, track-by-track IMAGE of a particular CD-ROM or DVD. It is NOT a usable data file in and of itself. To actually USE whatever files that .ISO image contains, you need to burn it to a new disk AS AN IMAGE, and NOT as a regular data file. You can use K3B for this, if you like:

1. - Make sure the .ISO file is accessible somewhere on your system (i.e., copy it to your hard disk, unless you have TWO optical drives so that one can be the source and one can be the target).

2. - Open K3B.

3. - From the pull-down menus, select "Tools", then "Burn Image...".

4. - A dialog box will pop up, from where you can browse to wherever the ISO file is, and select it.

5. - Set "Speed" and "Writing Mode" appropriately. (I generally force a somewhat slower-than-max speed, for safety's sake, and leave "Writing Mode" as "Auto".)

6. - Click on the "Start" button.

When the process is complete, you should now have a new disk with whatever contents the .ISO image file contained.

Thanks for responding.

In Dolphin, when, I try to use 'Devices 0B Removable Media', all I see is a message at the top of Dolphin in pink. The message reads ' An error occured while acccessing 'home', the system responded: The requested operation has failed: Error mounting system-managed device'

I have the iso file on my hard disk, and I am sure that I can burn it to a new DVD.

Do you think that the DVD is damaged, possibly due to removing it a little too early when burning?

A couple of other points.

What is the difference between burning and copying?

If I wanted to copy a file to a DVD why can't I just 'mouse it over'

Best wishes.

When you originally burned that disk, you may well have borked it in other ways besides mucking up the difference between an ISO image and a regular data file. At this point, I wouldn't worry about it.

Much more importantly: What happens (in K3B) when you insert a fresh BLANK DVD-R (or DVD+R) disk into the drive (remember to give it a few seconds to recognize the new media)? It SHOULD report that media (by type, etc.) in both the left-hand "pane" (where the file system "tree" is also displayed), and from the pull-down menu: "Device"" --> "Media Info". If you can't get at least that much right, you have larger problems, and likely cannot (reliably) use K3B and/or that drive and/or that system to burn media.

Good. Start there, using the instructions I gave you previously.

The disk you already have (with the ISO image on it in "data file" form) is useless by definition anyway (at least as long as you have another copy of the ISO file to burn a new disk from).

It sounds like you need to bone up on the basics of optical media in general. With a very small handful of special exceptions (none of which apply in this case), they are NOT "just another disk drive"; nor can they be treated as such.

'Much more importantly: What happens (in K3B) when you insert a fresh BLANK DVD-R (or DVD+R) disk into the drive (remember to give it a few seconds to recognize the new media)?

That is exactly what I would expect if you were to insert a blank CD-R disk; and if that's what you did, fine.

But I specifically asked about DVD-R and DVD+R, since that was what you said you were using. Now, this apparent discrepancy MAY be nothing more than a minor oversight on your part; but if you really DID use a DVD disk, and K3B still reported it as a CD-R, then something else is amiss. Are you sure your optical drive is capable of burning DVD media? What make/model is it (this should also be reported by K3B)?

I am now re-trying to burn the iso file to the appendable DVD-R that contains another iso file (the same DVD-R that is causing the problem, e.g., can't read in Dolphin).

I noted a fatal error at startup: input/output error.

I have given the debugging output below.

Can you see the problem?

You can NOT do that. It will NEVER work.

Go back to the instructions I gave you previously about burning an ISO image to disk, and follow them precisely, using a FRESH BLANK DISK of the correct type. (Note that "the correct type" is determined by the ISO image itself. It will have been created expressly for either a CD or a DVD, as required mostly by the size of the image and its intended purpose. While it is sometimes possible to burn a CD image to a DVD blank, it's generally not a good idea.)

And like I also said earlier, you definitely need to bone up on the basics of optical media.
