satelliteuser083 Posted July 23, 2007 Report Share Posted July 23, 2007 When I try to read a normal data CD I get the following error-message: Could not mount device. The reported error was: /dev/sr0: Invalid argument mount: I could not determine the filesystem type, and none was specified I'm using mva2006. Could anyone tell me what I have to change to solve the problem? Thanks. [moved from Software by spinynorman] Quote Link to comment Share on other sites More sharing options...
tyme Posted July 23, 2007 Report Share Posted July 23, 2007 Is this just happening with one cd, or several? Also, could you post the contents of your /etc/fstab file? Quote Link to comment Share on other sites More sharing options...
Kieth Posted July 24, 2007 Report Share Posted July 24, 2007 Usually, I read a CD, then it will not read a second one. I re-boot, and then it will read another. I can rarely read two different CDs without re-booting in between. Quote Link to comment Share on other sites More sharing options...
satelliteuser083 Posted July 24, 2007 Author Report Share Posted July 24, 2007 I've tried a number of CDs, same problem. Interestingly, KsCD will read (and play) an audio-CD but the read-failure occurs when I try to access it (the same audio-CD) via KDiskFree. Konquerer (via the Devices-icon on the desktop) also fails to open the CD. Here is my /etc/fstab file: # This file is edited by fstab-sync - see 'man fstab-sync' for details /dev/hda10 / ext3 noatime 1 1 /dev/sr0 /mnt/cdrom2 auto umask=0,user,iocharset=iso8859-1,sync,codepage=850,noauto,ro,exec,users 0 0 none /mnt/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,umask=0,iocharset=iso8859-1,sync,codepage=850 0 0 /dev/hde1 /mnt/pcmciafat vfat umask=0,iocharset=iso8859-1,codepage=850 0 0 /dev/hda1 /mnt/win_c vfat umask=0,iocharset=iso8859-1,codepage=850 0 0 /dev/hda5 /mnt/win_d vfat umask=0,iocharset=iso8859-1,codepage=850 0 0 /dev/sda4 /mnt/zip100 vfat noauto,user 0 0 none /proc proc defaults 0 0 /dev/hda6 swap swap defaults 0 0 Quote Link to comment Share on other sites More sharing options...
pmpatrick Posted July 24, 2007 Report Share Posted July 24, 2007 I've had similar problems with mdv2007 and mdv2007.1 except the cd mounts and sometimes shows garbage files. However, if I unmount the drive in a console and remount it there, the cd works OK: $ umount /media/cdrom $ mount /media/cdrom Try mounting in a console and see if you get better results.

adamw Posted July 24, 2007 Report Share Posted July 24, 2007 Remove this line from your /etc/fstab file: /dev/sr0 /mnt/cdrom2 auto umask=0,user,iocharset=iso8859-1,sync,codepage=850,noauto,ro,exec,users 0 0 it's confusing the auto-mount system.

neddie Posted July 24, 2007 Report Share Posted July 24, 2007 I've had similar problems with mdv2007 and mdv2007.1 except the cd mounts and sometimes shows garbage files.

Mine used to be there but since 2007.1 all my cds show up as /media/volume_label_of_cd ! Quote Link to comment Share on other sites More sharing options...
pmpatrick Posted July 24, 2007 Report Share Posted July 24, 2007 Didn't do anything special, neddie. That's just the way it was set up after install. Here's the fstab entries for my two optical drives: /dev/hda /media/cdrom auto umask=0,users,iocharset=utf8,noauto,ro,exec 0 0 /dev/hdb /media/cdrom2 auto umask=0,users,iocharset=utf8,noauto,ro,exec 0 0 I think my problem is an issue with udev or hal since a manual mount fixes the problem. Also, the problem is erratic so it's difficult to troubleshoot but I have the identical issue on two separate machines, one of them being a laptop, so I know it's not just some hardware quirk on one box. I was going to attach a screenshot but of course I can't get it to do that just now. At any rate a manual mount fixes the problem which is why I suggested the original poster give that a try.

scarecrow Posted July 25, 2007 Report Share Posted July 25, 2007 (edited) Oh no, not again...please. You can NOT MOUNT an audioCD, period. It does not have any real filesystem in, so it cannot be mounted. The only way to access its contents is via KDE's virtual filesystem... open konqueror, d3lphin, or whatever, and type in audiocd:/ ...and that is. Regarding a data CD, the syntax in fstab is impornant. But just comment in/remove ALL entries in fstab that have to do with CD-Roms, and try again- hal should take care of that without problems. The fstab CD-ROM entries are nowadays needed only to a handful of apps- eg wine needs an fstab entry to handle CD-ROM access from "fake" windoze environment.

tyme Posted July 27, 2007 Report Share Posted July 27, 2007 Mine used to be there but since 2007.1 all my cds show up as /media/volume_label_of_cd !That's HAL/DBUS. As for the OP, I recommend adamw's suggestion (that's actually why I wanted to see your fstab). I'm not particularly sure why Mandriva still puts fstab entires for cdroms if it's using automount (unless you added the entry yourself?). But then, I've also seen this issue on other Linux distro's (Arch did it for a while too). Quote Link to comment Share on other sites More sharing options...
Guest guardianX Posted August 3, 2007 Report Share Posted August 3, 2007 hi, guys, i suffer similar problem with my mandriva 2007. i can't access my cd-rom, and it is not showed in either media, or mount. my fstab as follows: /dev/sda9 / ext3 defaults 1 1 /dev/sda6 /boot ext3 defaults 1 2 /dev/sda8 /home ext3 defaults 1 2 none /media/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,umask=0,iocharset=utf8,sync 0 0 /dev/sda5 /mnt/win_d vfat umask=0,iocharset=utf8 0 0 /dev/sda2 /mnt/win_e ntfs umask=0,nls=utf8,ro 0 0 none /proc proc defaults 0 0 /dev/sda7 swap swap defaults 0 0 What should I do?

Put this line to the bottom of fstab: /dev/hda /mnt/cdrom auto umask=0,users,iocharset=utf8,noauto,ro,exec 0 0 reboot and see if this will help.

adamw Posted August 4, 2007 Report Share Posted August 4, 2007 demon: no, as I mentioned, there should be no need to add an entry in fstab. The problem lies elsewhere. I'm not sure where, though. Quote Link to comment Share on other sites More sharing options...
Demon Posted August 4, 2007 Report Share Posted August 4, 2007 Maybe it's a hardware failure then. guardianX, if you have any bootable cd or dvd, try to boot it to just to be sure it's not hardware failure. Quote Link to comment Share on other sites More sharing options...
Guest guardianX Posted August 5, 2007 Report Share Posted August 5, 2007 Maybe it's a hardware failure then.guardianX, if you have any bootable cd or dvd, try to boot it to just to be sure it's not hardware failure. I have try to boot via CD-ROM and it works. Then I also change ftsab like follows: /dev/sda9 / ext3 defaults 1 1 /dev/sda6 /boot ext3 defaults 1 2 /dev/sda8 /home ext3 defaults 1 2 none /media/floppy supermount dev=/dev/fd0,fs=ext2:vfat,--,umask=0,iocharset=utf8,sync 0 0 /dev/sda5 /mnt/win_d vfat umask=0,iocharset=utf8 0 0 /dev/sda2 /mnt/win_e ntfs umask=0,nls=utf8,ro 0 0 none /proc proc defaults 0 0 /dev/sda7 swap swap defaults 0 0 /dev/hda /mnt/cdrom auto umask=0,users,iocharset=utf8,noauto,ro,exec 0 0 However, it do not work, and still can't access my cd. FYI, mine is LG CD-RW . Thanks. Quote Link to comment Share on other sites More sharing options...
