Ubuntu :: Mount: Special Device /dev/scd0 Does Not Exist
Sep 12, 2010
The CD-ROM on this computer, my ubuntu laptop, does not seem to be working properly. It works on and off. I burned a .iso image yesterday but today I can't get it to even read the CD in my drive. I just want to read the CD to see if it is the Ubuntu Live CD I burned a while ago or if it is the Vista Recovery CD.
TL;DR: CD-ROM isn't working properly. When I click on the drive this is the error.
Code:
mount: special device /dev/scd0 does not exist
P.S. I am trying to get Windows Office to install using Wine because I am tired of windows. I know that open office is great. but I have to have excel 2007 and word 2007 for school.
why I'd be receiving this error. I have created a partition and filesystem and put the label in fstab. Everytime I reboot the server it is unable to mount the filesystem. However I am able to mount it manually.
Device/Special file Clairification Requested.I'm reading a short article on Device/special files because it is related to VFS. This article has this paragraph that has to many pronouns in it to get an understanding of. URL..."In short, a device file (also called as a special file) is an interface for a device driver that appears in a file system as if it were an ordinary file. This allows software to interact with the device driver using standard input/output system calls, which simplifies many tasks."
What does a Device file have to do with the Application and the Driver communicating? Wouldn't the order of data transfer be , Application to driver and then to Device file?
I've got an LVM2 VG containing 1 LV running on SLES11 SP1.
I have an entry in /etc/fstab to remount them at boot:
Code: /dev/myVG/ibmLV /opt/IBM ext3 defaults 0 0 Whenever I reboot the whole VG disappears and I find the following in /var/log/boot.msg: Code: <notice -- Apr 15 12:35:55.954677000> boot.localfs start Waiting for /dev/myVG/ibmLV . no more events
I made a duplicate of a Centos 5.5 system disk with dump (dd if=/dev/sda of=/dev/sdb). No device files for sdb were created, but I guess that's not too surprising. I rebooted, and the device files were created. But how would I create them if I wanted to avoid the reboot? I looked around for info on mknod and MAKEDEV but didn't find a lot.
I'm running mythbuntu 0.21 on a hardy environment. I had a thread under mythbuntu but i think this was the wrong forum. So here it is again
<lameexcuse> Currently i hesitate to upgrade to lucid because i fear problems coming up which i do not have the time to solve. The machine works generally fine so why upgrade to lucid? </lameexcuse>
I am dual-bootng Ubuntu 9.10 and Mint 8, both of which use GRUB2. The Mint 8 GRUB sets the initial menu since Mint was loaded after Ubuuntu 9.10. Since both use GRUB2 I was not concerned about this.
Both before the installation of Mint and afterward I see a series of messages fly by on the screen when Ubuntu is booted. These come right after the initial presentation of the Ubuntu logo.
By restarting several times I can read the first several lines. They are:
Mount: Mount Point 0 does not exist Mount 0 terminated with status 32 Mountall: Filesystem could not be mounted
Further lines follow but I would have to reboot umpteen times to have any chance of copying those.
I have looked in the various Ubuntu GRUB2 files for "Mount Point 0". I do not see any reference to it.
GParted, BKID and etc/fstab all agree on the UUIDs set for my Ubuntu/, Ubuntu Home and Ubuntu swap file.
I see nothing like this when I boot Mint 8.
My questions:
What is the point to error messages (I assume that is what they are) that fly by too quickly to be read? Are they saved to a logfile somewhere?
What is "Mount Point 0"?
What does it mean in this context to say "Filesystem could not be mounted"?
This is all very curious because Ubuntu proceeds to mount and run just fine.
What is Ubuntu trying to do as it starts up that it cannot do?
How do I repair whatever has to be repaired in order to turn off these messages?
I have looked through such GRUB2 dcumentation as I can find without seeing any reference to this.
what now trying to mount partition get this error this is the partition ubuntu 9.10 is installed on and upon reboot error no device with a long string. mount: can't find /dev/sda6/mnt in /etc/fstab or /etc/mtab
so now that I believe I've successfully mounted the partition how do I direct the bootloader to this partition /dev/sda6 on /media/11076e45-e27d-470b-bb6d-6894f7809a0c type ext4 (rw,nosuid,nodev,uhelper=devkit)
i'm running ubuntu 10.04 and windows vista on my laptop and I installed Dos box on ubuntu quite some time ago, when i went to mount my d drive (like i usually do in windows) I got the error message "directory D: does not exist" i tried to fix it myself but i gave up because it wasnt that important. A while later i read on a webpage that "Linux doesnot employ the concept of drive letters" so i thought this must be the reason for this error message but why would there be dosbox for linux if that was the case
OS: Ubuntu 10.04 (in VirtualBox virtual machine) how to mount a device for all users. I tried everything and can mount it only for root. I'm trying to mount shared device in VirtualBox virtual machine.I added record in `fstab` file:
shared /mnt/shared vboxsf rw 0 0
I got /mnt/shared permissons: drwx------I've tried to add options 'rw,user' in fstab, but the option 'user' is not supported by mount program in my system.
I installed ifuse (a utility to mount your iPhone or iPod touch via the USB cable) and I want this to be the default way my iPhone is mounted when I connect it. Currently, when I connect it, it gets mounted by the gvfs (Gnome virtual file system) at ~/.gvfs/iPhone. Either one change should be made (the 'default command to execute when this device is connected') or two changes (tell gvfs not to mount, and tell ifuse to automount). I don't know how I can get this to work.
In 10.04 I was able to plug in my MP3 player and move songs to and fro in Banshee or rhythmbox. Now, I can mount it, but it freezes banshee when trying to access it from banshee (it does appear in the list).
I am trying to expand my Ubuntu partition into my Windows 7 C: drive, but the win7 partioner will not let me shrink it because of immovable files. Is there anyway for me to but an loopback device in the windows partion, and have Ubuntu boot with that as the root device?
I'm developing a little script that automatically detects the insertion of a usb device and tries to open the directory of this device in nautilus. I am using Python
So far I was able to sample and compare the changes that occur in the output of 'lsusb' command and get information pertaining to the addition and removal of usb devices.
Now I want to know if we can use that information (or some other info present in the usb sybsyste --/sys/bus/usb folder) to determine exactly where this device has been mounted.
I know you might recommend using 'mount' as a quick way to do the same. I have already done that, but the limitation is that mount only gives u the mountpoint information. How does one (using a program/logic) determine which mount point corresponds to which device.
If I were to plug in two devices together, and both were automatically mounted, how will I be able to tell which mountpoint corresponded to which device? the output of lsusb provides no information whatsoever about where the device is mounted. So its kind of a deadlock
from lsusb ive been able to gather : Device name, serial and bus number and device number
Another thing i've noticed is the 'autoplay'. Whenever I insert a my music player into my computer, it gets mounted automatically and I'm presented with options about simply opening the file or playing it with rhythmbox... now if all that was being done was polling the output of mount, they would not be able to know that the device inserted was a music player (that info u can get from the /sys/bus/usb folder only using the device class and subclass info). So obviously the two are linked somewhere...
Recently installed some minor software, some games and Ubuntu Tweak, I am not sure if that's what caused this issue or not. I shutdown after the installations, then when I tried to start back up the small, white ubuntu logo appears just like it normally does, then it just goes to a black screen. I turned off the computer and restarted in (Recovery Mode). It goes about its thing then it says it is waiting for root file system, then after about 30 seconds it says "Gave up waiting for Root File System" how to fix this without reinstalling?
Sometimes when I restart, my NTFS drives will mount in incorrect directories. It seems to only happen when I plug in USB devices such as flash drives, and keep them in when I boot. I have the fstab file configured correctly, but it still resorts to some odd default mounting points. Edit suposedly the device name changes whenever I boot with a flash drive plugged in. Is there anyway to mount a disk to a dir without pointing to its changing device name.
I just plugged my phone containing a new SD card (bought this morning) to my PC, in order to transfert some data. The problem is that the device is detected in lsusb but doesn't appear in fdisk output (otherwise I could mount it by mount /dev/device_name /mnt/temp). It doesn't appear in GParted or as desktop icon, even after rebooting my PC keeping the device plugged in.
Is it possible to mount the SD card using the lsusb ID? Here are my outputs (the device has ID 0fce:01a7)
Code: Select allroot@dynamic:/home/dovah# lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I'm trying to mount my NAS device via NFS with suse 11.1, but up to now it failed. The NAS does support NFS, but it requires a UID and a user name and up to now I could not figure out the correct nfs mount options for that.
If I just make mount 192.168.0.2:/nas1 /mnt a get the error message "mount.nfs: access denied by server while mounting 192.168.0.2:/nas1". So can somebody please tell me the correct options for user name and user id which the mount should use. And, preferable the correct entry for the etc/fstab file to make this mount being executed automatically during startup. I studied the mount(8) and nfs manpages several times, but I do still have no idea how to make it.
How can I find which /dev/? device to mount my USB hard drive on redhat 3 taroon, I've been googling a lot and checked log files and still no clue. I'm trying my last chance with you experts, # /sbin/fdisk -lgives nothing about the USB drive

Current stable Debian runs on both machines. I connect a digital camera to the USB on the server ("a") and the camera's filesystem is mounted automatically.I want that same filesystem to be made available to the other machine ("b") through nfs.What should be in fstab for that filesystem, or is something else needed in the configuration for "b" in order to access the filesystem which is physically on "a"?
I am trying to set up my usb device to be available to mount and umount only for me, not for other users. Using Slackware 12.2Entry in fstab is as follows:
I posted a similar problem sometime last week...but a little has changed(mainly I can access my files now): I recently performed the auto upgrade to Ubuntu 10.04 and upon restart of my machine I am presented with 3 screens. The first is a simple "GRUB loading". The second is "mount: mounting none on /dev failed: no such device". The third screen is a series of initializations, i.e. /dev/sda1:
clean, (number of files), (number of blocks) *setting preliminary keymap... and so on until it hits the line: *checking battery status
at which point it will cease loading until i press the power button. The next thing that occurs is it kills all the processes it just initialized and shuts down the computer. I read that this is likely a problem from loading the wrong kernel and I can get into my files (using a boot 9.10 boot key). The problem is I don't know what files to change in order to get my system booting the right kernel.
I got a sort of usb connected device(not an external enclosure) so i can connect a sata hard drive into a machine that only has ide connections but the drive is not mounting. I am not very good at mounting slave hard drives anyway ,,,,never been able to get one happening without help. I am wanting to read this drive as i killed another desktop machine(i think the mb) and i need the data off the hard drive. The drive is shown in a directory and in the media directory. Can't think of what else sorry as i am so tired from testing everything out of the machine that i killed.....
