I guess you could say that I'm a slightly educated noob (I know, a little knowledge is a dangerous thing).

My drive worked fine in Mint 17.3, but I am now running Lubuntu 16.04 and my DVD drive has not worked yet. I have tried multiple CDs and DVDs; music, data, and blanks.

lsblk -f returns:

sr0          

cat /dev/sr0 returns:

cat: /dev/sr0: No medium found

So I tried lshw and got this:

*-scsi
     physical id: 2
     logical name: scsi0
     capabilities: emulated
    *-cdrom
         description: DVD-RAM writer

         logical name: /dev/cdrom
         logical name: /dev/cdrw
         logical name: /dev/dvd
         logical name: /dev/dvdrw
         logical name: /dev/sr0

         serial: [
         capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
         configuration: ansiversion=5 status=nodisc

And then there's this:

$ mkdir ~/dvd | sudo mount /dev/sr0 ~/dvd
mount: no medium found on /dev/sr0

I'm pretty much grasping at straws at this point. So, what now?

Update on info: I can locate it in Disks with no problem, but it shows no media when I have a DVD in the drive. I have already cleaned the lens, but that was never an issue as it worked fine before I installed Lubuntu 16.04

  • Try running dmesg just after inserting a disc, to see if any errors are reported. – muru May 15 '16 at 19:33
  • Okay, dmesg returns a long, long list of things I don't completely understand. Such a long list, that I can't scroll to the top in fact. What, exactly, am I looking for and is there a way to trim down the information to make the results more relevant? – Bus42 May 15 '16 at 19:41
  • Focus on the bottom, the newest messages, immediately after inserting a disc. If it helps, run dmesg -w and watch for new messages as you insert the disc. – muru May 15 '16 at 19:43
  • Edit your post to include large output, please. Use code formatting the way I have done while editing your post. – muru May 15 '16 at 19:45
  • Well, I'm throwing in the towel. It seems to be a kernel issue and well beyond my capabilities. I'm going to try installing another Ubuntu distro to see if it's specific to the distro. If that doesn't work, I'll install an older, not-so-flashy distro such as Puppy Linux, which my DVD drive worked fine on. Thank you sincerely for your time and help. – Bus42 May 16 '16 at 0:21

Actually your system does find the drive and identify it properly as well, as a Sony DVD RW AW-G540A. Your output provided indicates that the difficulty is in reading from the drive which the system is convinced is empty as you mentioned. The root cause is likely a failed laser (since you've cleaned the lens). The device if it's repairable at all isn't worth the cost to repair. I recommend replacement of either the drive or the entire laptop (if the budget can handle it) considering the age.

    I tried the cdrecord mkisofs... It didn't work. There some errors, but I really couldn't understand them. – Jonathan MilTech Benjamin Aug 15 '16 at 12:09
