The reason you still get the message is because you still have rw in
the line, and they can only mount ro. I just changed rw to ro for both my drives in /etc/fstab and as I alluded to before, that made the informational message disappear. I don't know where to get the documentation, but I can tell you this. You cannot write directly to a CD-RW or DVD+/-RW drive using Linux, nor Windoze, for that matter. They must use some app to do it - some software must turn on the lasers Scotty!, or the job is not going to get done. Don't let this mount issue get you off track. For the purpose of looking at a CD/DVD, just mount the thing. When you want to burn, you'll have to use a program to accomplish that. It's either K3b or something else, K3b being simply a frontend (IMO) for the real software which is actually doing the burning. But note this: we didn't "mount" the devices in the 2.4.x and prior kernels before burning, and you won't "mount" them to burn now. Look at this output. I only post it so you can see the command, given properly: Code:
mingdao@james:~$ mount /mnt/dvd desktop just as well. Right-click on the icon, select mount, then a little green arrow appears on the bottom right of the icon. Click on the icon and view the files with the Konqueror file browser. Close the browser, right-click on the icon again, choose Unmount, and the arrow disappears. Right-click on the icon again, choose eject, and the drawer pops open. I can stick a disc in the drawer, close it, and just click on the icon and it will open the file browser and mount the device. If it doesn't seem to unmount it the first time you click, click again. Mine do all manner of strange things, but they will mount, read, unmount, eject, etc. I don't know how much simpler it could be, but I still like Fluxbox and cli lot's better. How did you create the icons on your desktop? This is how I did it, and it's working here. First I left-clicked on the little wrench icon on the toolbar, then I selected Desktop > Behavior and right-clicked that, then I selected Device Icons and put a checkmark in Mounted CD Writer, Mounted CD-ROM, Mounted DVD and Unmounted CD Writer, Unmounted CD-ROM, Unmounted DVD. You might ask, "Why did you choose 'Mounted CD-ROM and Unmounted CD-ROM also, when the other choices are correct for the devices?" The answer: because the icons didn't show up with only CD Writer and DVD selected. They only showed up after I selected CD-ROM too. Now, do you see why I prefer the cli? I call this a bug - KDE probably calls it a "feature." Either way, it's incorrect, illogical, and impractical. Which is my opinion of guis. But, I'm trying to help you and your family. NB: Don't forget you also need to make your regular DVD mount as a drive (/dev/hdb) and not as a symlink (/dev/cdrom). In /etc/fstab if I were you, I would change this Code:
/dev/cdrom /mnt/cdrom/ iso9660 noauto,user,rw 0 0 Code:
/dev/hdb /mnt/dvdrom iso9660 noauto,user,ro 0 0 PIONEER DVD-RW mount to /dev/dvdrw just because IMO that's logical. Okay, hope this gets you on the right path. |
ok, adding ro worked - guess I missed that suggestion.
now, pardon my ignorance - but how exactly do you allow non-root to umount? thanks! |

the information correctly. Quote:
and we're now mounting it correctly with "$ mount /mnt/dvd" but got Quote:
changed rw to ro and got rid of that message. The next thing we see is Quote:
filesystem on a directory. So you should issue "umount <directory>" which in this case would be "umount /mnt/dvd" to unmount it. NB: I have the option user which allows only the user who mounted the filesystem to unmount it. The option users allows every user to mount and unmount the file system. If user sasquatch has mounted a filesystem, and a different user (i.e. mingdao) is trying to unmount it, then you need to change user to users in /etc/fstab. If this doesn't address the present problem unmounting the filesystem, please post the exact output of the command you are issuing and use the -v switch to get verbose output - which I believe should be "$ umount -v /mnt/dvd" If it works correctly in a terminal, but doesn't work correctly in KDE, then the issue is with whatever gui frontend KDE uses to mount and unmount the device. But please do it in a terminal so that we can actually see if your system calls are working correctly. If so, then you've eliminated that and you can go on to find out why the KDE guis don't work. |
I seem to have the same problem here. I was about the edit the fstab but when I tried to get the iformation from my dmesg file I foud a problem...
Here is a copy of my dmesg file: hda: ST340823A, ATA DISK drive hdb: LITE-ON LTR-52246S, ATAPI CD/DVD-ROM drive blk: queue c03b3360, I/O limit 4095Mb (mask 0xffffffff) hdc: WDC WD400EB-00CPF0, ATA DISK drive hdd: JLMS DVD-ROM LTD-166S, ATAPI CD/DVD-ROM drive blk: queue c03b37b4, I/O limit 4095Mb (mask 0xffffffff) ide0 at 0x1f0-0x1f7,0x3f6 on irq 14 ide1 at 0x170-0x177,0x376 on irq 15 hda: attached ide-disk driver. hda: host protected area => 1 hda: 78165360 sectors (40021 MB) w/512KiB Cache, CHS=4865/255/63, UDMA(100) hdc: attached ide-disk driver. hdc: host protected area => 1 hdc: 78165360 sectors (40021 MB) w/2048KiB Cache, CHS=77545/16/63, UDMA(33) hdb: attached ide-cdrom driver. hdb: ATAPI 52X CD-ROM CD-R/RW drive, 2048kB Cache, UDMA(33) Uniform CD-ROM driver Revision: 3.12 hdd: attached ide-cdrom driver. hdd: ATAPI 48X DVD-ROM drive, 512kB Cache, UDMA(33) Now, the problem here is that both the DVD and the CD-R/RW are listed under hdb What do I do??? |
Here is a copy of my modified fstab:
/dev/hdc2 swap swap defaults 0 0 /dev/hdc1 / reiserfs defaults 1 1 /dev/hda1 /WindowsXP ntfs ro 1 0 /dev/hdd /mnt/dvd iso9660 noauto,owner,ro 0 0 /dev/hdb /mnt/cdrw iso9660 noauto,owner,ro 0 0 /dev/fd0 /mnt/floppy auto noauto,owner 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 proc /proc proc defaults 0 0 assuming hdd is my dvd and hdb is my cd-r/rw when I try to mount any of the drivers I get the following error message: mount: wrong fs type, bad option, bad superblock on /dev/hdb, or too many mounted file systems Any suggestion? |
Mounting CD-ROM or DVD-ROM as read-write will not work hence they are read-only. To make a CD or DVD, use cdrecord or dvdrecord. You may need to upgrade cdrecord and dvdrecord so they can work properly under kernel version 2.6.x. Also from looking at the previous posts. It seems your PATH variable is not setup properly. You should have something like "/bin:/usr/bin:/usr/local/bin:/usr/local/sbin:~/bin" when you type "echo $PATH".
Your fstab file should have: # PIONEER DVD-RW DVR-105 /dev/hdc /mnt/cdrom auto ro,users 0 0 # SONY DVD-ROM DDU1612 /dev/hdb /mnt/dvd auto ro,users 0 0 ernesto_lelo: Change iso9660 to auto. Also take out owner and in its place add users. From your first post, your DVD drive is at hdd and the CD-RW is at hdb. BTW, It took two pages for Chinaman to answer a mount problem. :rolleyes: |
ernesto_lelo,
We truly should express that when you start asking questions in others threads they have started to seek answers is looked down upon in most cases, especially if they haven't come to a resolution for their problem. Some call it hijacking the thread. As its not part of our stated rules, we ask members not to do this and start new threads with their own questions they may have, even if its the exact problem in the thread you've so-called "hijacked" If you have any questions or concerns, feel free to email me, another moderator or the site admin. Thanks. |
