I have a functional CD-ROM with lots of Windows stuff inside. I know that the executables won't run on Ubuntu, but I cannot even get the system to mount it.

I'm sure it's user error. But, I'd love to access the files/folders on this disk as there are some PDF files that are very important for me.

Can anybody help me?

edit: Adding in pertinent info

I'm on a Dell Inspiron 5559 Intel® Core™ i7-6500U CPU @ 2.50GHz × 4 Ubuntu 18.04

When I put a disk like this in the tray spins up, then nothing. File manager doesn't see it. Disk Manager app won't mount it. It's like it's not there.

Music disks, DVDs, & blank discs all register fine and appropriate apps open.

Here's the return from lshw with a Windows disk in:

        *-cdrom
         description: DVD-RAM writer
         product: DVD+-RW DU-8A5LH
         vendor: PLDS
         physical id: 0.0.0
         bus info: scsi@1:0.0.0
         logical name: /dev/cdrom
         logical name: /dev/cdrw
         logical name: /dev/dvd
         logical name: /dev/dvdrw
         logical name: /dev/sr0
         version: DD11
         capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
         configuration: ansiversion=5 status=ready
       *-medium
            physical id: 0
            logical name: /dev/cdrom

Attempting to manually mount it via

mount /dev/sr0 /mnt

Returns

mount: /mnt: no medium found on /dev/sr0.

But the disk is in there. And from lshw above, the system knows it's there.

When running journalctl --follow, I do not understand any of the output that occurs when I insert the CD. In fact, it looks irrelevant (if so, I'll delete later). That all looks like network traffic.

Disc mode is listed as: Error in getting information
++ WARN: error in ioctl CDROMREADTOCHDR: No medium found

cd-info: Can't get first track number. I give up.

I wonder how will I know if it's the drive or the disk. The disk works on other machines. The drive works with Music disks & blank disks. So, both work in some cases.

  • Would be crear if you could provide some diagnostic information. Do you know how to run commands in a terminal?

  • Yes, I am able to run terminal commands. I'd be happy to give you whatever diagnostic info would help!

  • Are you getting any errors? and what did you try. What version of Ubuntu? I grabbed a cdrom at random (quickverse, windows software) inserted it, and a short time later the disc span up & a notification with the disc name appeared at the top of the screen with close or 'open with files' options. I am using GNOME or the standard Ubuntu 18.10 UI (same as 18.04). If I open term and enter lsblk at the bottom of my devices I see "sr0 11:0 1 109.1M 0 rom /media/guiverc/5532D_QV_CD" which is the CD. More details of your version, and what you tried, if the drive span up are helpful...

  • Eject the CDROM. Start journalctl --follow in a terminal window. Insert the CDROM. Any interesting log info from journalctl --follow?

You say that system can't mount it!

Did u try manual mount from the terminal? as root you would be able to mount cdrom with no issues:

mount /dev/sr0 /mnt

or create your own directory and instead in /mnt you mount it on that directory.

  • Attempting to mount returns: mount: /mnt: no medium found on /dev/sr0. But it's in there. And the system knows it (see edits to question above).
