Mounting an iso file

Hi,
I have the feeling that this question has been already asked 1000 times but I still haven't found a solution, so here it goes...
I created an iso file of a (data) dvd using k3b on some other computer; now I want to mount it.
I have tried the following:

sudo mount -o loop -t iso9660 /path/to.iso mnt/dvd
fails with
[10500.914004] ISOFS: Unable to identify CD-ROM format.
[10500.922975] UDF-fs: No anchor found
[10500.922978] UDF-fs: Rescanning with blocksize 2048
[10500.923411] UDF-fs: No anchor found
[10500.923412] UDF-fs: No partition found (1)
[10505.392216] UDF-fs: No anchor found

[10505.392493] UDF-fs: No partition found (1)
[11244.268231] ISOFS: Unable to identify CD-ROM format.
in dmesg|tail.

fuseiso -p path/to.iso mnt/dvd
fails with
init: wrong standard identifier in volume descriptor 0, skipping..
[...]
(same until descriptor 18).

Anyone has another idea of what I can try?
Thanks in advance,
Antony

Re: Mounting an iso file

Maybe you're missing a '/' in front of your 'mnt':

mount -o loop tinycore_3.5.iso /mnt/dvd/

works for me.
(I don't have any data DVD to try)

BTW, hen pasting code, please use [ code ] tags https://bbs.archlinux.org/help.php#bbcode

like this

It makes the code more readable and more convenient to scroll through.

Re: Mounting an iso file

No, I created a mnt folder in my $HOME just for testing. So I'm not missing a /. And doing this in the actual /mnt folder doesn't work either, it gives me the same errors.

Re: Mounting an iso file

Have you googled that error message?

Re: Mounting an iso file

I've never used 'k3b' - but from the error-messages it would seem that it is in udf-format rather than iso.
Try 'mount -o loop -t udf'

Re: Mounting an iso file

I think this might be because you are trying to mount a dvd iso, but the iso9660 type is specific to CDs (according to wikipedia, CDs use the iso9660 filesystem, while DVDs generally use udf).

Have you tried mounting without the -t option and letting mount try to determine the type automatically?

sudo mount -o loop /path/to.iso mnt/dvd

or, if that doesn't work, try specifying udf:

sudo mount -t udf -o loop /path/to.iso mnt/dvd

Hope this helps.

Re: Mounting an iso file

Seems like the problem is the one suggested by karol, i.e. k3b actually creates a .img and not a .iso.  I'll have a look at mkisofs, and thanks all for your suggestions.

Re: Mounting an iso file

Perhaps isomaster is the tool for your project..
