Ubuntu :: Can't Mount Cdrom Or Usb After Replacing Optical Drive
Mar 24, 2010
My cdrom was sort of working, but the tray was physically damaged. The usb was working without a problem.
After replacing the the cdrom drive with a similar model known to work well I could not get it to mount. I then tried to move important files to usb to try a fresh install. The usb stick flickered when I put it in, but it didn't mount. Same behaviour as the cdrom, the light goes on when I turn on the computer, but once I'm logged in I can't access the cdrom.
I have tried multiple variations of playing with fstab and trying to mount things in terminal to no avail. I just can't get Ubuntu to recognize the usb or cdrom even though their lights go on when I first try to use them.

I dont know when k3b stopped working but have just gone to burn a disk and when opening it tells me
Quote: No optical drive found. K3b did not find any optical device in your system. Solution: Make sure HAL daemon is running, it is used by K3b for finding devices.
I can boot from cd and can mount cds from within Slackware but for some reason k3b insists that i don't have a drive.

I tried to mount my CD Rom drive and got this response: "mount: can't find cdrom in /etc/fstab or /etc/mtab"
I did see the CD Rom drive briefly after I upgraded from 10.04 to 10.10 but I couldn't access the drive and when I logged back in.

Is there any dvd drive with longevity? The boxes in this "normal" house have had 100% failures on dvd writers and readers in recent years. I'm an electronics guy and know why this happens - minute changes in the careful balance on the reading head, not helped by the facts that:
1. low grade adjustable resistors are often used
2. The range of adjustment is far too great, making it impossible to retain a stable preset value.
3. Optical diodes lose forward voltage drop over time. If they start at, e.g. 1.2V after some months or years the forward voltage will be down to 1.0V. This changes the current, hence the brightness.

how to get a bash script to automatically launch when the optical drive mounts a disc, any type of disc - DVD, CD, data, etc. It seems like such a simple task but after weeks of searching I have yet to find a workable solution.

Finally got FC8 installed on new machine, and now it won't mount CDs/DVDs - didn't change anything in BIOS, CD/DVD drive is only thing on the IDE controller (HD is SATA) so is it likely a driver issue? FC8 seemed to have correct (or at least working) drivers for LAN, audio, SATA, etc.

I am trying to mount a a Magneto Optical WORM drive, mechanically it is a 2.6 Gb, 1024 Bytes/Sector, 5.25", Verbatim Media, The disk was created under OS-2.
I am using CentOS 5, and have tried mounting the disk as msdos and as vfat and get superblock errors among others.
what filesystem type did OS-2 use? is there an add on to CentOS that will support the filesystem?

I'm trying to get a script to run whenever an optical disc is mounted by the system but can't get it to work. I'm running Fedora 12 64bit and the drive is SATA device sr0.
Following online guides, I created a new rule file called '10-my.rules' in '/etc/udev/rules.d' which contains the following:
Code:
KERNEL=="sr0", RUN+="/usr/local/bin/myscript"
But nothing happens when a disc is mounted. The script itself runs fine manually and is clearly evident when launched so the problem must be the rule file. I've tried changing the name of the rule file in a few incremental steps from 10-my.rule to 99-my.rule to no effect.
I've gathered some information about my optical drive using the udevadm tool.
Here is the result of an info query:
Code:
P: /devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0/block/sr0
N: sr0
S: block/11:0
S: scd0

So if I boot without a DVD or CD in my optical drive, then I attempt to put one it, it doesn't mount. I try mounting with the terminal and that fails as well. If I boot with the media in the optical drive, it works fine. (this problem occurs both on my desktop and laptop and I know the DVD and CD's work in both 9.10 and in windows, This error also occurs with Linux Mint and Sabayon leading me to believe this is a kernel issue).
[Code]...
What do I need to do to get this to work like it should? I have been asking about this since the beta of 10.04

I have this rather old Compaq Presario 2184 (Celeron processor), with a completely busted optical drive - which means I cant boot from Live CD, and it doesn't boot from USB, either... which means I cant use a live memory stick, either. It's currently running Xubuntu 9.04.
I'm seriously running short of space on my root partition - can't upgrade to 9.10...
I had a Windoze partiion that I decided to remove, using Gparted. Identified the NTFS partition, right click, delete. After that, I couldn't do anything else... I then found this page, that told me that I cant resize all partitions while booting from hard drive, and that I needed a Live CD. For the reasons mentioned above, that's just not possible...
Are there any alternatives that the good folks here can suggest? For example, can I create a new partition, and move my entire /usr there? It would solve the space problem, but I'm not confident of doing it without screwing up something... could someone kindly guide me through the process?

I exchanged my CDROM drive for DVD drive. The DVD is recognized in the BIOS (will boot to DVD install disc) and in CentOS 5.2 (when I list the hardware), but CentOS must still think it's a CDROM drive. When I run VLC in a terminal it kicks back these errors code...
I think this means that "hdc" is linked to a CDROM configuration somewhere, but I don't know where to find it to change it (or out it). It also appears thee is no DVD module loading. (Of course, I could be making poor guesses.)
I thought there might be something in the fstab, but it doesn't appear there is anything there (for the CDROM or DVD drive)?
Is there somewhere else I should be looking? /dev/*** ?

I have a pc with linux mint installed, and wanted to try edubuntu with my kids. The first time we tried, it booted just fine from the dvd, as the bios is already set to boot from dvd as priority. So it ran off of RAM.
Subsequent tries however, result in the pc booting mint from the hdd, and no sign of edubuntu at all. I have tried different distros/isos, but to no avail. I have also opened the box to see if the dvd drive had somehow come unplugged.

I currently have the following:-
Optical Out from my TV into the SPDIF / Optical In on my PC
Optical Out from my PC into my Sony 5.1 Theatre Kit
The audio from the PC comes through ok when listening to music and movies. But unfortunately I can figure out how to enable the audio passthrough from my Tv so that the audio comes out of my theatre kit. In Sound Preferences, the hardware is set to 1 Output / 1 Input [Digital Stereo (IEC95 Output + Digital Stereo (IEC95 Input]. When I click on the audio tab, the Input Volume is at 100% and the Input Level is moving in conjunction with the audio coming from the Tv.
I saw it mentioned in another thread to install Gnome Alsa Mixer which I've done, it seeems to identify the audio chipset as Realtek ALC882, the motherboard is an Abit AB9 Pro. Hopefully I'm missing some config somewhere or there a box I should be ticking but I just can't find it.

I tried to burn a cd today and k3b told me it couldn't find an optical device. It suggested making sure HAL was running, it is. Nothing has changed except auto upgrades, so I tried an apt-get upgrade to see if that would make a difference. It didn't. Burning has never been an issue before, and googling all day hasn't provided any answers, apart from finding /etc/init.d/hal The permissions haven't been changed.

I have a strange problem with my DVD player. The problem: My device seems not to read any CD (it does read DVDs). Prologue: On a previous installation I had the same problem. But after messing up with that system I made a re-install, and the problem was gone. So I wasn't concerned about the problem any longer. That would be fine, but recently I had to make a new re-install to have space for windows. (I know, I'm a sinful man) But now the problem is there again. And it even is there under windows.
Question: In how far is the hardware damaged or is it a software problem since it once worked? Hardware data:
-Systems: Fedora 12 & Vista
-Laptop: Dell Studio 1555
-Drive: Optiarc Model: DVD+-RW AD-7640S Rev: HD18
What I have been doing to fix the problem:
-I made an update of the firmware and bios with the files provided by dell
-cleaned the lenses (with a clean disc)
-checked log files (both windows and linux)
After setting udev to debug logging I received this

I seem to be having a problem with burning CDs. Whenever I launch k3b, it says 'No optical drive found.' However, When I insert a CD while in KDE, it properly mounts it. What do I do? It seems like udev/hal is working fine. Also, I can't get KDE to recognize any inserted flash drive or external usb storage device inserted on demand.

Hardware is a Supermicro with C2SBC-Q board, have set up a RAID1 with 3 WD drives, the BIOS "sees" the "LightScribe" DVD drive but it is not being recognized by CentOS (5.2 x86_64). It's on an IDE bus, set to "master".# dmesg | grep -E 'CD|DVD|hdc' produces a new prompt with NO feedback, BTW.I have CentOS 5.2 i386 running on this machine with the same DVD drive, it was not an issue.

1- If I have a motherboard that supports USB boot (a Supermicro one), how can I put the CentOS DVD .iso that I just downloaded onto the stick to have the computer boot from it?
2- Certain Supermicro boards support IPMI (Kvm over LAN) and Serial over LAN and most notably Virtual Media Over Lan. I am wondering if there would be any problem installing CentOS using the Virtual Media over Lan.

My girlfriend has a dual boot netbook I set up for her with Vista + 9.10. Her internet service went down yesterday temporarily and she was messing around with the computer to get back online and somehow booted into the Windows Rescue Partition and began the Windows Restore process, then turned the computer off during the middle of the restore process.It's her only computer and she lives 1800 miles away. And since it's a netbook there's no optical drive.
When she boots up now, the netbook goes straight into Grub Rescue mode. I got her to try most of the commands for Grub Rescue, but most of them come back as "Unknown Command". The "LS" command works though, and she was able to get a list of partitions displayed.Does anyone know of some commands she could use try to boot back into 9.10 (assuming it's still there)? Or even boot into Windows? Specifically, is there a simple command that could be combined with "LS" to specify a partition and try to boot into it?

Sorry if this question might sound stupid I'm a complete noob here. I bought an ASUS EEE PC 901 second hand and had reformatted the hard disk with a fresh installation of Ubuntu 10.10 netbook remix. formatted the 2 drives as follows : 4 gb hard disk space ext4 , and 8 GB hard disk space ext4 This was after countless problems with Ubuntu 11.04 Desktop edition previously not being able to connect to the internet via my home wifi router. I took the advice on this forum somewhere, someone said 10.10 NBR will not have issues with wifi connectivity. Tried it and it worked. On my current Ubuntu NBR 10.10 installation, absolutely no wifi connectivity problems whatsoever.
Now my brand new MyLink portable USB Optical Drive which plays DVDs and CDs has arrived in the post. I open it, plug it into my ASUS eee pc 901. And nothing happened. I am used to using Windows and its Plug and Play function. Now for the life of me, this just doesn't happen in Ubuntu right now. The computer does recognise the drive though. Under Applications > Disk Utility I can see the optical drive right there and there's an option to use Brasero to copy and burn DVDs. However no option to play. I tried using the Movieplayer that comes installed with this Ubuntu version to play the DVD I'd insertedd into the drive, but on clicking "Add file" to try and search where on the system the DVD file is located, nothing turns up. All I can see are my home directory and the files on my hard drive.
The external optical drive came with a CD with the drivers on the CD, meant to be installed I think. But I have absolutely no idea how to install it on Ubuntu. Or if I need to install it.Can anybody help me out please? I'm starting to think maybe I should have just stuck to the Windows XP that came with this netbook. I would prefer to stick with Ubuntu though as its supposedly faster than Windows...

I'm trying to backup netbook files to an external optical drive. I can read discs but not write. A while back I tried using K3b but it did not see the external drive. Now it does, but tells me write access is needed and quits. I am in the cdrom group.

The culprit is a Toshiba Samsung Storage Technology 222A CD/DVD RW drive, aka SH-S222A, sold under the Samsung brand. It occasionally locks up my entire system when I'm ripping an audio CD to a *.toc/*bin image with Brasero. I've had this happen with several different audio CDs, while ripping discs using both Imgburn under Windows XP and Brasero under Ubuntu 10.04. The display freezes completely, the mouse cursor doesn't move, and I can't get any response to keyboard input. Any sounds playing loop endlessly, repeating the last 0.5 sec or so before the cursor freeze. Meanwhile, the hard drive activity light stays on, but the optical drive light does not. I've let the system sit this way for several minutes, with no sign of change. To recover, I must press the system reset button.
I ripped the same discs without incident, using my other optical drive. It is a different brand, Lite-On, but otherwise similar to the Samsung drive: PATA interface, CD/DVD RW, etc. Anyone else have the Samsung SH-S222A? I'm wondering whether there is a bug in the drive's firmware, or I just have a defective drive. It works for other things. I can play audio CDs, access CD-ROMs, and rip audio CDs to individual tracks (rather than a disc image). I can also rip DVDs. Is there some way to recover my system when it locks up from drive misbehavior? I haven't found a way so far. I'm surprised that Ubuntu can be incapacitated so easily.
The SH-S222A has the most recent firmware revision, SB01. I tried to install the newer ID01 firmware from Samsung's website, but got a message that the installer couldn't find a "suitable" drive. I take that to mean that the ID01 firmware is meant for a slightly different variant of the -S222A, perhaps one only sold overseas. Yep, that's pretty much it. My drive's customer code is BEBE. Firmware ID01 is for drives with a different customer code.
