General :: Difference Between /dev/hdc And /dev/sr0, /dev/cdrom
Apr 19, 2011
I created 2 virtual machines with VMware Workstation 7. They have identical hardwares. One guest is CentOS 5.6, another is Mandriva 2011.
When I try to mount the cdrom in guest OS, in CentOS, I should execute
mount /dev/hdc /path/to/mount
in Mandriva, I should execute
mount /dev/sr0 /path/to/mount
I also remebered in some other Linux variant, I had to use
mount /dev/cdrom /path/to/mount
What's the difference between hdc, sr0 or cdrom? Is there a consistent way to mount cdrom in all Linux variants?

I'm using a software that needs to read data from a cdrom. The instructions say to mount the cdrom (mount /mnt/cdrom). I understand that I need to mount the cdrom to /mnt/cdrom. I created a folder "cdrom" under "mnt". Then I tried to mount the cdrom by typing:
sudo mount /media/ /mnt/cdrom/ This didn't work. Under "media" I have another folder with the actual cd content so I tried to mount it too, but again with no success. I keep getting an error that "media is not a block device". What I am doing wrong?

I'm trying to get back into Linux after a few years off.
I have tried booting from a Live CD using Flash Linux and Damn Small Linux.
Flash Linux reports unable to mount CDROM and then provides a command line - I assume I have the kernel, a shell and little else at this point? Can I mount the CD and continue?
DSL seems to do something similar but freezes with a blank screen. I have the option of entering parameters prior to booting with DSL (but not with Flash) I have tried the parameter which copies the CD to RAM and then boots without success.
I plan on installing Debian to my HD in the near future but felt like playing around with Live CDs prior to this in order to get reacquainted.
I have googled this issue and it seems there are other noobs out there with the same model of PC (HP DV6) who are having similar problems but I could not find a solution.
As an aside - this is the kind of issue that IMO, still prevents Linux from becoming a mainstream OS.

In case somebody has a PC with
- mainboard ok
- RAM ok
- terminal.. ok
- a defect CDROM = no CDROM
- a defect floppy = no floppy
- a defect HDD = no HDD
- an IDE connector inside the PC
- an USB port but cannot boot from there (BIOS is too old).
Then I would
-> buy a compactflash card (>2GB) approx 10 Euros
-> buy an USB-Compactflash adapter approx 5 Euros
-> buy an IDE adapter for compactflash card aprox 20 Euros
-> ask a friend or a shop to install KNOPPIX on USB+Compact Flash (easy on KNOPPIX 6.2 through a menu "install on flash card")
-> put the compactflash + IDE adapter into the PC and boot from there (BIOS setting must be correctly done; easy job)
Then later buy a small HDD for installing the personal data on it. Has somebody a quicker or cheaper method?

I'm having a problem updating the cdrom. the error i get is Failed to fetch cdrom://Ubuntu-Netbook 10.04 _Lucid Lynx_ - Release i386 (20100429.4)/dists/lucid/main/binary-i386/Packages.gz Please use apt-cdrom to make this CD-ROM recognized by APT. apt-get update cannot be used to add new CD-ROMs. I tried using apt-cdrom, it tells me the commands and options, which i wrote down for reference, but still that has an error which is, E: Unable to stat the mount point /media/apt/ - stat (2: No such file or directory)
W: Failed to mount '/dev/sr0' to '/media/apt/'
E: Unable to change to /media/apt/ - chdir (2: No such file or directory) Is there another code to recognize the cdrom? because the help of the command and options list didn't give a code for recognizing the cdrom. Im using ubuntu 10.4lts on my netbook and yes i do have a external rom

Laptop has broken internal CDROM. I booted with floppy to get Puppy 431 installed from USB stick. Now I have USB CDROM access thru Puppy. I can mount and see the CD fine.
Is it possible to boot or install from a currently installed linux distro (Puppy)?
I have a second free partition ext2 available, sda2, and GRUB is working fine for me on boot.
(machine also doesn't have boot from USB option, yes, it's old, a project I am working on, I have Nimblex in CD now, I think it's a live cd, I would like to try a few different ones by installing to sda2 and wiping if ng.)

I bought a new CDROM drive, as recommended by HP. It still doesn't work. I can open and close it now; so that's changed. But it still doesn't appear as a drive, and I can't use it.
Here's as best as I can describe it:
When starting up, the boot order doesn't recognize the cdrom drive, but I can open and close the drive during this time.
In Windows 7, I can't open the cdrom drive, and it doesn't recognize it in device manager, disk management, or my computer.
In Ubuntu Linux, I can open the cdrom drive, but it still doesn't recognize the cds, and it won't mount.
If I reformat everything, would my cdrom drive work again? Can I reinstall Windows without a cdrom drive? I've deleted the upper and lower filters as was suggested in Google searches. Took the disk drive out and checked that it was installed correctly (no reason it shouldn't have been). Still: nothing works.

I am new to this and just got a SUN Netra 440MHz T1 105 with 512MB RAM, 2 19G SCSI drives and a IDE CDROM.I am having trouble loading Ubuntu 9.05 server iso via the CDROM. The CDROM driver does not get found and the installation aborts. The CDROM is a 24x toshiba XM-7002B.I can load the old Ubuntu server 7.10 but cannot update it. (would need some help to do that, too).

I need to install a bios update to fix my PC after I upgraded the CPU. BIOS update should fix it.
But...This seems to be way harder than it should be. I'd be great if motherboard manufacturers could provide bootable iso images with all the tools to do the job without us having the build these ourselves...
Anyway, how do I go about creating a freedos bootable CDR under Kubuntu that is BIGGER than 1.44 MB!
My image file is 1MB already. The flashing program 32KB. I tried the methods from the various forums and just couldn't get them to work. Either ran out of space, or all the links to fdos were broken.
By the way, [url] doesn't seem to be right anymore and thats where everyone is pointing. I would probably have had this sorted if I could have the 2.88 MB image, but all I can find is a 1.44MB image and I have now idea how you can grow that to a bigger one. Why be stuck with 1.44MB? are we still in the 1990's ?

df -k

21G used[code].....
The 3.4G is correct because we have removed all non essential file but free space reported by df is not consistent with the actual free space that should be there.
