Can't mount usb cd rom in ubuntu 8.04
My cdrom is not mounting on ubuntu 8.04. I find this message in syslog (below). How can I resolve this?

From a quick goolge this seems to be a harmless error message from the Intrepid kernel. It's not necessarily the reason your drive is not mounting.
Do you get anything from lsusb related to the drive? What is the last line in dmesg just after you plug it in? |
I have an external usb that sometimes when I plug in it doesn't automatically detect, but it is seen by disk utility.
Anyway I can mount using disk utility or just reboot. Obviously I just don't know command , but that's my work around. Also if there's no media there's nothing to mount. |
Ubuntu 8.04 is two and a half years old. Depending on your kernel, you may have to modify your /etc/fstab to get the device to mount reliably.
The output of sudo dmesg will tell you whether your computer is seeing the device. I normally like to add such devices to fstab. It just simplifies matters. |

Hi, Let me know what error you are getting while mounting CD-ROM on a folder or a mount point ? Because Ubuntu detecting your CD-ROM device properly. Please run below command as root or sudo an tell me output,
sudo mount /dev/cdrom /mnt ... |

Let's say is shows up as "sdc." It is being seen as /dev/sdc, since devices are seen to be in /dev. The next step is to create directory in either /mnt or /media to which to mount the device. You can call it anything you want, for example, "joe." (The traditional way is to use /mnt; the current way is to use /media.) So we create a directory Code:
mkdir /mnt/joe Code:
mount /dev/sdc /mnt/joe We unmount the device with Code:
umount /mnt/joe Code:
/dev/sdc /mnt/joe auto rw,user,noauto 0 0 "Mount the device seen as /dev/sdc to /mnt/joe, auto detect the file type, make it read/write, allow any user to mount the drive, do not mount it automatically." See the link I provided earlier for the meaning of "0 0." We should then be able to mount device with Code:
mount /mnt/joe For comparison, here is the dmesg output for my external USB HDD. Since it is already mounted and partitioned, the partitions also show. Note that it is seen as sdb; the remainder of that line refers to how the partitions are seen: Code:
[ 8.340046] scsi 2:0:0:0: Direct-Access MICRONET FANTOM DRIVE 2.10 PQ: 0 ANSI: 4 Code:
/dev/sdb1 /media/sdb1 ext3 rw,user,auto 0 1 I would not have understood a word of this five years ago. |
