Determine filesystem of unmounter .iso image

I am Gianluca · 2012-04-16 20:32:40

Hi,

I want to open an .iso file. I know that I can do it with this command:

mount -o loop /home/gianluca/vocabulary.iso /mnt/vocabulary/

But it ask me to specify the filesystem type. How can I know it?
I create the .iso file converting a .nrg file.

Thank you for your time,

Gianluca

Try

mount -o loop -t iso9660 /home/gianluca/vocabulary.iso /mnt/vocabulary/

Did it work?

alphaniner · 2012-04-16 20:41:39

Run file on the iso: file /home/gianluca/vocabulary.iso. If it's a valid iso, output should be similar to

$ file data.iso 
data.iso: # ISO 9660 CD-ROM filesystem data 'Data                            '

Thank you! Unfortunately it returns me this:

$ sudo mount -o loop -t iso9660 /home/gianluca/vocabulary.iso /mnt/vocabulary/
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

/home/gianluca/vocabulary.iso: data

Is 'data' a filesystem?

alphaniner · 2012-04-16 20:46:40

No, 'data' means it's unrecognizable.

Could it depends on the fact that I convert a .nrg image to .iso?
I used this command:

sudo nrg2iso vocabulary.nrg vocabulary.iso

I still have the .nrg image on my HDD, but if I try to run file on the .nrg file it returns me the same error.

bjornoslav · 2012-04-16 20:53:51

Try this

mount -o loop -t udf /home/gianluca/vocabulary.iso /mnt/vocabulary/

Did it work now?

No, it didn't.

# sudo mount -o loop -t udf /home/gianluca/vocabulary.iso /mnt/vocabulary/

Install IsoMaster

sudo pacman -S isomaster

and try to open it there. Can you see its contents?

I am Gianluca · 2012-04-16 21:08:32

It tells me:

Failed to read volume info: 'First volume descriptor type not primary like ISO9660 requires'

If I try with the .nrg image:

Failed to open iso file for reading: 'Failed to open file on the filesystem for reading'

bjornoslav · 2012-04-16 21:16:03

Something's wrong with the image. From what kind of disk you were making an .nrg/.iso?

alphaniner · 2012-04-16 21:16:33

At this point, I think that the nrg file may be corrupt. Either that, or it is a "track-at-once" image; according to wikipedia, nrg2iso can't convert this type:

nrg2iso — cross-platform. hardcoded to read all nrg files as disc at once (DAO) type causing it to fail on track at once (TAO) type images.

I don't know. It the CD included with the book Cambridge Vocabulary for first Certificate. There are several audio tracks related with the exercise of the book.
I need it because I don't have a CD player on my laptop. So I asked to a friend to create an .iso image, and she gives me this .nrg image.

If it was made from an audio CD, there will be no filesystem (and it should not be mountable). Maybe try opening the iso with a media player.

However, the best solution, if the source was an audio CD, would be to rip it to mp3 or some such.

Ask your friend to convert the tracks to some audio format - mp3/ogg/flac/etc.

I am Gianluca · 2012-04-16 21:36:13

I can't read it with VLC.
I will try asking my friend to convert it in mp3.
Thank you guys!

I suggest you try this: https://wiki.archlinux.org/index.php/Mo … er#fuseiso

I am Gianluca · 2012-04-16 21:53:52

I didn't work:

fuseiso /home/gianluca/vocabulary.iso /home/gianluca/temp/
init: wrong standard identifier in volume descriptor 0, skipping..

Same if I change the mountpoint to /mnt/vocabulary/

bjornoslav · 2012-04-16 21:56:29

I believe that file is an Audio CD, a 17-track one.

Open VLC, click menu Media > Open Disc...
In the new window that appears, in Disc Selection choose Audio CD, then click Browse... (near Eject-like button).
Open the file. Does it work?

I am Gianluca · 2012-04-16 22:02:49

I was thinking the same thing before open the thread. Unfortunately I can't select the .iso image if I use the Media > Open Disc way
I see it but can't select it.

bjornoslav · 2012-04-16 22:04:26

Type the path to the image in the Disc device text box and see if that works.

I am Gianluca · 2012-04-16 22:11:52

It returns an error message:

Your input can't be opened:
VLC is unable to open the MRL: 'cdda:///home/gianluca/vocabulary.iso'.

I've never had luck converting anything to iso, but,
https://wiki.archlinux.org/index.php/CDemu
this always works.
