crazyspongebob Posted October 27, 2004 Report Share Posted October 27, 2004 Hi all, I remember posting this problem before but not getting a good answer. Last time I did not have a screenshot of the message. I'll let the picture speak for the problem. I have this problem usually while opening mozilla. When this comes up, I hit the cancel button. The computer slows down considerably. I don't know what happens. I have Mandrake 10.0 on an AMD Athlon 800 with 384 MB RAM. I also have a laptop with PIII 1ghz and 512 MB RAM running Mandrake 10.0 without any problem at all. Any suggestion? Thanks JT Quote Link to comment Share on other sites More sharing options...
dickohead Posted October 27, 2004 Report Share Posted October 27, 2004 that's just an alert to let you know have put a cd in the drive that conmtains music and data (a mixed cd)...... somewhere in gnome config (i'm a kde user) there will be an option to turn that off surely..... try the gnome help files.

crazyspongebob Posted November 10, 2004 Author Report Share Posted November 10, 2004 I don't use gmone. I am using KDE. I don't have the same problem with my laptop. The dialog box just come up randomly. Somehow it says that there is a music cd in the drive, but I don't have anything in the cdrom drives at all. Thanx Quote Link to comment Share on other sites More sharing options...
chris z Posted November 10, 2004 Report Share Posted November 10, 2004 three things to look in to......... 1. do you have KSCD (KDE's CD player) running & docked in the panel? if so, quit it from the panel. there's an issue with KSCD that will cause the drive to lock if KSCD is running in the panel, even without a CD inserted in the drive. 2. do you have supermount enabled? if so, try disabling it & see if the problem goes away. to do so, in terminal as root do........ supermount -i disable you can re-enable it if you like by doing....... supermount -i enable 3. if all of the above fail, do this in terminl as root........ lsof /mnt/cdrom (replace cdrom with whatever yours is called. IE: cdrom0, cdrom1, etc) or........ lsof /dev/hdX (where X is the letter of the device) lsof stands for LiSt Open Files. it's quite a handy tool. if the command gives you an error "command not found", then you need to install it. to do so, in terminal as root do.......... urpmi lsof it's on one of the install CD's.

AussieJohn Posted November 10, 2004 Report Share Posted November 10, 2004 A thing which comes to mind after seeing your screenshot is that such a cd had both normal cd tracks and also a video clip track which is digital and therefore recognizes it as a data track. While you can still usually play the cd music tracks, If you try to rip the tracks using GRIP you will have no success. It will not read the music tracks or any tracks. Yet in Windows, that marvellous CDEX ripping program has no difficulty dealing with it at all. Cheers. John. Quote Link to comment Share on other sites More sharing options...

I don't have any disk in any of the 2 cdrom drive and KSCD is not running. So I'll try other options that you point out to see what happens.

I guess this is the problem that makes my box hang randomly, and I have to give it a cold reboot. Where should I put this command so when the system boot, it will run without me issuing it.

chris z Posted November 11, 2004 Report Share Posted November 11, 2004 could you please post the contents of /etc/fstab? Chris Quote Link to comment Share on other sites More sharing options...

crazyspongebob Posted November 16, 2004 Author Report Share Posted November 16, 2004 Hi all, I wonder if this whole CD-ROM drive locking up thing is part of the fact that the system might be compromised. I have a post in the security forum of this box with title "Users losing KDE" thread. Thanks J.T. Quote Link to comment Share on other sites More sharing options...
chris z Posted November 16, 2004 Report Share Posted November 16, 2004 have you tried the lsof command i suggested when the cdrom is locked? if not, do so while it is locked & post the results here. if that don't pan out, then try editing your cdrom fstab line to look like this............. /dev/hdc /mnt/cdrom auto iocharset=iso8859-1,codepage=850,noauto,ro,nosuid,umask=0,user,exec,nodev 0 0 that's from my fstab. almost identical to yours except the "nosuid" & "nodev" entries. i'm not 100% sure, but nosuid is a security feature to prevent just any user from accessing the drives. nodev disables magic dev, which is supermount's replacement in Mandrake. edit fstab using kedit. that will create an automatic backup of your old fstab for you. or, copy your old fstab before editing it to a different directory as a backup. that way, if something goes screwy by editing fstab, you can just replace it with the backup.

crazyspongebob Posted November 19, 2004 Author Report Share Posted November 19, 2004 It's not only CD-ROM drive lock-ups, but also whole system lock-up. I have to cold boot the system. I have not tried lsof command yet since I am trying to discern what's going with the possible security breach I posted in the security section. Thanx.

crazyspongebob Posted December 14, 2004 Author Report Share Posted December 14, 2004 I installed mdk 10.1 CE and used it for a while without any problem with the CD drives at all. Two days ago, after having probems with burning the mdk 10.1 official iso's on to CDs, I installed it and began having the same CD drive lock-ups problem with the same dialog box appearing on the screen. Any ideas? J.T. Quote Link to comment Share on other sites More sharing options...
