Hello: The box is dual boot (Win XP & CentOS 5). A Dell Dimension 4300 Celeron. There was an intermittent problem with this last year and last Thanksgiving, I wiped the HD and installed Win XP and CentOS 5 clean. My daughter asked me to install KStars which is in the kdeedu RPM on the Fedora Core 6 Install DVD. I did that, without any problems, on my box and on my wife's box. On the Dimension 4300, in Linux, the OS thinks the DVD ROM is empty. I suspect this is a HW problem, but: (a) Windows can see everything on the DVD, without any problem and (b) I can boot the Fedora Core 6 Install DVD, without any problem. If anyone on the ML has ideas about what might be wrong with the installation of the OS (I have GNOME and KDE installed and the problem is the same with either desktop) please give me your suggestions about how to get the DVD to mount properly. TIA!

It was my box, before my daughter got it, and I used the DVD drive, without problems. That it works OK in MS Windows XP and that I can boot the box from the same DVD, without problems, has me leaning more toward a problem with CentOS 5 Mounting the DVD, in that box. If it is a HW problem, I would think the problem would also appear in Windows and when I boot from that DVD. However, that it works OK, in 2 other Desktops, would possibly indicate a HW problem in that box. TIA, Lanny

I also suspect it is an OS problem, but, it seems to be very HW dependent. After I read your post, I got the FC6 Install DVD and put it into the DVD reader in my box. Zero problems. The same in my wife's box. But, in my daughter's box, I have the same situation that you described above. I suspect it is something about the DVD reader in that box.

Mine is a Dell Dimension 4300. I believe the DVD reader was not installed in the factory and that I installed it, later, but, I'm not positive about that. I also believe that the Dell Dimension 4300 had CentOS 5 on it, before I wiped the HD last Thanksgiving, but, I'm not positive about that. Certainly this was working on that box, when it was mine. My daughter rarely puts removable media into that box and the drive has little use, but, that does not mean that it might not be dirty or faulty. However, the drive seems to work properly, at all times, under Windows XP. That these boxes can boot from the same DVD media, and then not be able to mount the media properly, after the installation is complete, is frustrating.> Did you do a mount /dev/hdc /mnt/media?I tried that but I got this error message: mount point /mnt/media does not exist When I look at the /etc/fstab files in the box with the problem and in my box, they look identical or nearly identical. Where is the configuration file for removable media now? I suspect that somewhere in the auto mount process, it has a problem with the HW for the DVD reader for my daughter's box and for the DVD reader in Mike's HP box. When a DVD is inserted into the DVD reader, the DVD shows up on the GNOME Desktop, but as if the media is empty.

I may edit the file and see if including that cures the problem. Currently updating several packages on the box with the problem, including autofs and hal. If that does not help, I just began to think about updating the Kernel, hoping there might be better support for that DVD reader in a newer Kernel. But, I'm not sure if the support for the HW is the problem. I get the Digest version of this ML every morning, but I read your reply on the ML Archives. Thank you! Lanny

Upstream does not include the kdeedu RPM in their distribution, so CentOS doesn't have it and that package is something we use here. I think CentOS5 is based on FC6. That's the only RPM I'm using off the FC6 Install DVD and it works fine on CentOS 5. Thank you Mark! Lanny

Any particular reason?We didn't have ADSL before and I have been selectively updating rpms. That box is now running kernel 2.6.18-53.1.14.el5 :-) The problem still exists, after the kernel update, and as someone else suggested, I will probably post on the GNOME list for any ideas someone there might have. Neither of the GNOME modules mentioned in the TipsAndTricks/HAL article that you mentioned above are available for update: (a) gnome-volume-manager and (b) gnome-mount When I updated the kernel, I also updated hwdata and kudzu. If we knew what is causing this to happen, there could be a fix, but it remains a mystery. Thanks much! Lanny

That rpm has been installed. :-) However, I would like to eliminate this problem. The main user of that box is 7 1/2 years old and I can't give her root access or expect her to know how to use the CLI. She has been using Linux boxes for several years, but with a GUI.> I am a firm believer in command line usage, so I'm really not at all > clear on what the importance of being able to access the DVD via > Nautilus is.

Someone else here on the CentOS list replied to this thread, that he also has this problem, on an HP box. Also, I'm going to try Alan's idea and swap the DVD readers between the problematic box and my box and see if the problem moves with the DVD reader that is now in my daughters box, or, whether it is with that box itself. Thanks for the idea of posting on the GNOME list. I will do that! Lanny

I am going to try to swap the DVD readers, between my box and my daughters box, tomorrow morning, and see if the problem goes with the DVD reader that is now in my daughters box, when I install it in my box, or, if it persists in her box, with the DVD reader I now have in my box. Also, our Desktop boxes all have GNOME and KDE installed on them. The problem is *not* limited to GNOME. KDE also sees the DVD media as blank, when the FC6 Install DVD is in the drive.

I temporarily hooked it up in my box. The exact same problem! I could not see the contents of a DVD-R, but, I was able to see the contents of my Knoppix Live CD, without any problem. So, I did not bother with the PITA of removing the DVD/CD reader from my box, and trying that one in my daughters box. I booted my daughters box with my Knoppix Live CD V. 5.1.1 and it also showed the FC6 Install DVD to be blank. I suspect: (a) The Teac DV-516D DVD/CD reader is not supported in this kernel or somewhere else in CentOS 5. or (b) The DVD/CD reader is somewhat faulty. (c) However, Windows XP shows it to be "OK" and I can see the contents of the FC6 install DVD OK, in Windoze. Also, I can boot from the CentOS5 and FC6 Install DVD's, without any problem. And, I was able to mount the FC6 Install DVD, in a terminal and install the RPM I wanted to install, without any problems. Thank you, very much, for your time and ideas! Lanny

The problem did not go away. On CentOS 5, the Teac DV-516D DVD/CD reader can mount a CD, without any problem. However, it sees a DVD as blank. On Windows XP, it works perfectly, with CD and DVD media. I sent an email to Teac Tech Support, asking for the URL where I could download their Diagnostics for the drive and got this reply:>Unfortunately, no diagnostics are available as checking the readcapabilities within >Windows XP is most than acceptable. If the drive does not work properly within >Windows or any other PC, then the drive needs to be repaired or replaced. Disappointing and I will probably never purchase Teac components again. The box is dual boot (WinXP & CentOS 5). Years ago, I purchased SystemSuite 4. I installed that and ran their generic diagnostics on the Teac DVD/CD reader and it passed. I am not positive the Teac drive is working perfectly, but I have a high level of confidence in it. My belief is that somewhere, there is either no support for the Teac DV-516D in CentOS 5, or, that something required to automount a DVD in it is not configured properly. It can mount a CD without any problem.

I strongly suspect that your idea of replacing the Teac CD/DVD-ROM with something else, is the only way to end this problem. My belief now is that there is no support to auto mount a DVD in that Teac drive, in CentOS 5. Probably, when it was my box and it worked OK, it was with a prior release of CentOS or Fedora Core and something has changed and the auto mount support for that drive (for DVD media) was removed. I rarely use Windoze, but it was very helpful, to be able to test the same CD/DVD-ROM drive and verify that it works perfectly under Windoze. I was able to mount the DVD in a terminal and install the RPM I wanted to install OK, so that also makes me believe the drive is OK. Lanny

About 6 months ago, I bought an LG DVD Burner for my wife's box and it works fine.

The contents of the DVD are then shown.>Another thing Right Click on My Computer Select Manage and look at the >logs for the dvd drive in question. You should see errors there if it's >bad. Also like someone else said it will only auto mount on a user >account and not root.MS Windows Logs do not seem to have anything bad. It will not auto mount on my user account on CentOS 5.>If it's not any of the above get a new drive.Probable cause: Auto Mount of a DVD in the Teac DV-516D DVD/CD reader is not supported in the Kernel in CentOS 5 (or the Kernel on the Knoppix Live Disk v. 5.1.1); OR, there is something, somewhere, in CentOS 5 causing it not to auto mount a DVD when logged in as a regular user. A DVD can be mounted, manually, via the command line, without any problem. I believe the drive is working properly. Eventually, I will buy a DVD burner for that box. Thanks to everyone who participated in this thread and gave me things to try! If the same (unknown) thing is preventing auto mount of a DVD in an HP box Mike has,that might be interesting to Upstream as well as CentOS.
