I am not sure what I am supposed to see. The screenshots are very blurry.

It's also not clear what the problem is. Do you mean that there is a disk in the drive but you can't access it?

Few simple questions.

Do you have a disk in the drive? Can't mount an empty drive.
If you do, is it a data or video disk? iso9660, UDF ?

Depending on what you have installed. What is the output of

Code:

lsblk
dvd+rw-mediainfo /dev/sr0
fdisk -l /dev/sr0
parted -l /dev/sr0

hd_scania · 04-28-2020, 07:53 AM

Code:

[hd_scania@hd-scania ~]$ lsblk|grep sr0
sr0      11:0    1  1024M  0 rom  
[hd_scania@hd-scania ~]$

Then, for the next 3 commands there must be nothing in their output (yes nothing), even though there is a DVD inserted.
And all the 8 are A/V disc.

Simply, there are DVD’s inserted on my laptop’s internal DVD ROM, but that ROM could never read any DVD’s, I have 8 but none could be read.

Video (or audio) DVD's or DVD-ROM's (that is, DVD's with computer files on them)?
For the first you'l need a DVD ripper program, only the DVD-ROM can be mounted as a fs.

What do you do to read them, and in which way does that fail?

If these are audio CD's, you can't mount them. Audio CD's don't have a file system on them. You play them with a media player.
This is what a burned data DVD looks like:

Code:

lsblk | grep sr0
sr0     11:0    1   4.1G  0 rom

sudo fdisk -l /dev/sr0
Disk /dev/sr0: 4.13 GiB, 4427350016 bytes, 2161792 sectors

Also multisession disks usually need to be finalized to be read, or it might just read as the last session.

You can mount a video DVD also, but it is content scrambled. You can also mount a bluray disk, in a bluray capable hardware, not in a older dvd player/burner.

If you run vlc or other media player from the command line, what errors do you get?

hd_scania · 04-29-2020, 05:50 AM

Only one is audio CD, but the final seven all are DVD’s with movies
And the 7 movie DVD’s are reported to me empty or no media, both from VLC and Dolphin and XFburn, now await for Brasero results where i’m yet to install that app.

Installed all the rippers available, and choices are few, now await for mount results as for my final seven DVD’s.

It just simply says, no media are found, nothing to be mounted, but all the 7 DVD’s are with their respective movies.

Where there is an DVD inserted on my DVD ROM, it still doesn’t report any error codes at all, but just frozen like the screenshot.
So, any skills to mount DVD’s (as always for /dev/sr0 to be shown sth to me) properly, effectively, precisely where basic mount commands and graphical apps all don’t do this well?

What is "it"?

DVDs have a filesystem on them, as was remarked earlier. See if this works:

Code:

mkdir /mnt/dvd
mount /dev/sr0 /mnt/dvd

hd_scania · 04-29-2020, 06:34 AM

There is at least an DVD already, and finally all seven DVD’s are tested, but NONE are reporting their respective contents.

Code:

[hd_scania@hd-scania ~]$ sudo fdisk -l /dev/sr0
fdisk: cannot open /dev/sr0: No medium found
[hd_scania@hd-scania ~]$ sudo dvd+rw-mediainfo /dev/sr0

Already tried this but it always reports no media found from /dev/sr0, the total 7 DVD’s are getting this
