Go in as root to your device and mount points and check that you indeed have read/write permissions set properly -- that means they should be enabled (checked) for whoever uses the drive. As I had trouble with this, I just gave everyone that right. Permissions are OK - I checked these first off. Like I said, if root doesn't have permission, who does? 3. Go to your CD icon on the desktop, or in your directory. Right click on the icon -- does the word "mount" or "unmount" show up in the menu? If yes, then you should be able to click it. If not, then you have the wrong device / mount point attached to your icon. Here I get fuzzy, because this is where I had the most trouble and am not sure (yet) what got me out. If neither "mount" nor "unmount" shows up on the file menu, delete the icon from the desktop. Go to HardDrak under filesystems and see if the CD is visible there. If it is, then play with the settings until it works. If it's not, then go to /dev/### (I don't know the device name for your CD, and try to copy that to the desktop. Click on that and work with the properties. The trick is to get the "mount" and "unmount" show up when you right click the icon. The devices are shown as mounted and are shown under HardDrake. However, they remain inaccessible. -- Graham Watkins

[newbie] Can't access CD drives - even as root
Here's a funny thing! Whenever I try to access either of my CD drives, whether as root or user, I am refused access. Using Konqueror, I get the message: "Unableto enter file:/mnt/cdrom. You do not have access rights to this location." - if root doesn't have access, who does? My CD drives are shown under /mnt with little padlocks on them. Using a terminal command: ls /mnt/cdrom, I get the message "Input/output error". The only way I have ever been able to get round it is to boot from a floppy rather than LILO - this is a hassle. If anyone has encountered and solved this problem, I would be grateful for guidance. I am running Mandrake 7.2 (never had this problem with 7.1) and my drives are a Mitsumi 4802TE (re-writable) and Samsung SCR232 Graham Watkins

Re: [newbie] Can't Access CD Drives - even as root
Try this as root in terminal mode: Type in as one line: (make sure spacing is correctmake sure you have the semicolons and the "s alias CD+="mount -t iso9660 /dev/cdrom /mnt/cdrom; cd /mnt/cdrom; ls -aF --color=auto" also type: alias CD-="cd; /mnt/cdrom" (That's CD-) Be sure you have a CD in the #1 tray. Type: CD+ You should see the contents of the CD now type in CD- ( You can't remove the CD until you execute CD- ) You can check your other CD (#2) by making aliases for CD2+ and CD2- substitute cdrom2for cdrom If you're satisfied with the results. put these commands verbatim in/etc/bashrc then restart your computer. You'll be able to access any CD. with CD+ ( or CD2+ ) and restore with CD- (or CD2-) Please let me know direct if this worked for you. I'm just a newbie too but I stayed at the Holiday Inn once.

Re: [newbie] Can't Access CD Drives - even as root
Sorry about the garble in my previous message---here's a better version, I hope. Again, use care with the spacing---single space alias CD+="mount -t iso9660 /dev/cdrom /mnt/cdrom; cd /mnt/cdrom; ls -aF --color=auto"
RE: [newbie] Can't Access CD Drives - even as root
At first if you want to use your CDRW you should enable scsi emulation, which can be done by putting the following lines in your LILO config file: append hdc=ide-scsi , if your CDRW drive is connected as Secundary Master ,don't forget after this rerun lilo , and take a look at /dev/cdrom to see references to real devices as example dev/cdrom - scd0 or dev/cdrom - hdc Of course you can run HardDrake and go to cdrom section to refer how your drives is recognized - normally should be two entries for CDRW one as hdc device and one as scd0 device.

Re: [newbie] Can't Access CD Drives - even as root
What do the /etc/fstab and /etc/mtab files look like? My first guess would be that the system has been set up to expect a file system type other than what you are trying to mount (ie. it's expecting a linux disk and you are trying to mount an ISO9660 CD). I've seen this happen occasionally when the system attempted to use the "supermount" protocols. The second thing that comes mind is that the wrong drivers are being used for your CD roms. Both of these could cause the errors you are reporting. In order to test the first possibility : from a shell type the following command as root (onece you've inserted a windows CD): mount -t iso9660 /dev/cdrom /mnt/cdrom. If it is simply a matter of the wrong file type, this will successfully mount the windows disk.

Re: [newbie] Can't access CD drives - even as root
** Reply to message from root [EMAIL PROTECTED] on Tue, 13 Mar 2001 16:12:54 + A couple of things to look at: 1. Whatever account mounted the CD should also unmount the CD. Logical right? Not quite, because it doesn't always work. 2. Go in as root to your device and mount points and check that you indeed have read/write permissions set properly -- that means they should be enabled (checked) for whoever uses the drive.
