I just get ubuntu 12.10. So I am a newbie.

I have sata hard disc with partitions - sda 1 (swap) sda 2 (mount point /) and sda 3 (mount point /home).
Today I add another internal hard disc (not sata) which I plan to use only for data, and its mount point is /media/sdb1.

But after adding another HD ubuntu doesnt mount my dvd rw drive any more.
I get this error:

mount point media cdrom0 does not exist

I tried in terminal:


and get this:

mount: can't find /cdrom in etc/fstab or etc/mtab

What should I do?

I looked in /dev. A file there was called dvd. I entered ' ls -al /dev/dvd ' and it told me that this was a link to /dev/sr0. I inferred that from this response:

lrwxrwxrwx 1 root root 3 Apr 24 15:56 /dev/dvd -> sr0

The first 'l' means that it is a link, not a real file.

Then, I looked at /. There was a directory there called 'mnt', the usual node for subdirectories of mounted peripheral devices. It was empty.

I made a subdirectory of /mnt using:

sudo mkdir /mnt/cdrom

Then, I mounted sr0 there with:

sudo mount /dev/sr0 /mnt/cdrom

To see, I looked at it:

ls /mnt/cdrom

It came up with a lot of right-looking stuff, so I concluded success.

If you want to mount a cd/cdrom/dvd/whatever manually, you should first look in the directory /dev, for example with ls /dev. It is probably called dvd1. Then mount it with sudo mkdir /mnt/dvd1 && sudo mount /dev/dvd1 /mnt/dvd1.

I got cdrw1 in /dev. I try this and get: mount: no medium found on /dev/sr0 –  user132378 Feb 15 '13 at 21:22
mount: no medium found on /dev/sr0 I would like to have rw drive to mount on every start of OS,like it use to. –  user132378 Feb 15 '13 at 21:29
