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:
NAME FSTYPE LABEL UUID MOUNTPOINT

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
product: DVD RW AW-G540A
vendor: SONY
physical id: 0.0.0
bus info: scsi@0:0.0.0
logical name: /dev/cdrom
logical name: /dev/cdrw
logical name: /dev/dvd
logical name: /dev/dvdrw
logical name: /dev/sr0
version: 1.W0
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

Best Answer
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.
