Cdrom won't mount, "cdrom busy"


FC#/KDE3.3
When first putting cd in drive and clicking Cdrom icon , it won't mount and read,
Keep getting "cdrom busy" and if I click on eject "eject fails" I gave eject a chmod 777
and still does not help. some times I have to reboot box to get cd out of drive.
I do have better luck "Sometimes" to right click on icon click "open" and it mounts
and reads, then I have to right click and "unmount' then eject to get cd out.
I removded the application autorun from my box to prevent KDE from automounting.
The cd/writer drive is set up as a icon on Desktop /dev/hdc /media/cdrecorder anfd
below is the cdrom in /etc/fstab ;

/dev/hdc /media/cdrecorder auto pamconsole,fscontext=system_ubject_r:removable_t,ro,exec,noauto,managed 0 0

I do have the latest version of udev-039-10.FC3.2
I also shutoff the automounting feature in Gnome and Gnome will mount , read,
and eject with a breeze and no errors.
This has got to be a KDE problem.
And I mainly use KDE.

Thanks
Jim

I think I may have come up with a sensiable answer , If you got another I would like to hear (read) it.
When Kde starts , autorun mounts CDrom ,now it is mounted, and if you doible click on cd Icon it gives
you a "busy" error message. If instead you right click on icon and select "open" , then it will read the cdrom,
to unmount ,you right click an select "Eject" it unmounts and ejects cd. Sure ain't the way $Windows does it !!

Mounting and unmounting is a normal feature for linux and unlike windows.

Basically any time you want to access a filesystem wether or not it is a CD, floppy disk, hard drive, USB device, etc etc it needs to be attached to the file tree first. This is accomplished by the mount command. In the case of the CDROM drive and some other removable drives like the Jaz and Zips the drive is also locked. In the process of attaching the filesystem read / write buffers are also opened. unmounting the filesystem performs any delayed writes still left in the buffer, closes the buffers and removes the filesystem from the file tree.

It takes some getting used to but after a while its no big deal. I am not up on the differences between the latest versions of Gnome and KDE and they do have different features. I assume you have also noticed that seperate drives do not exist. All devices exit within the file tree. In fact everyting is considered a file.

Mandrake by default installs supermount which will automatically mount filesystems when accessed and unmount after a period of inactivity. It isn't perfect and I usually end up disabling it.

See man pages for the mount command & search the internet for additional information.

I've been using RedHat/FC for a while, and I think what we both mean is that the routine of mounting a CD has changed (for us anyway).

In previous versions I could insert a CD and left-click on the icon to open the folder. It now seems to give the "busy message" when I do that.

Thanks for the information, I will re-read the 2nd reply. Hopefully, there will be a bug-fix in the future.
