I'm running precise pangolin on my laptop and always keep it updated. I've had some problems with the cdrom not being recognized by K3b before, but got it fixed by changing the permissions. But this time it seems that it is totally vanished from my computer. I've tried many different things that users had suggested on this website and many other websites, but none seems to work. Ironically, it works just fine when I boot to windows.
Here is the output of some commands:
$ sudo wodim --devices
wodim: Overview of accessible drives (0 found) :
-------------------------------------------------------------------------
-------------------------------------------------------------------------
and
$ sudo depmod -ae
doesn't seem to do any good for me.
Also, for some reason there was no /dev/cdrom or /dev/cdroms or /dev/dvdrom folder on my computer. Nothing even similar to that.
My fstab looked like this:
proc /proc proc nodev,noexec,nosuid 0 0
UUID=50424cf6-6dd8-4d34-a441-dd964f67ea97 / ext4 errors=remount-ro 0 1
UUID=ebf67e0f-3597-4ed9-bedc-73a4e8049071 /boot ext4 defaults 0 2
UUID=e22d709a-c084-4fbf-bad3-2fef352e7e75 /home ext4 defaults,user_xattr 0 2
UUID=94ca0e7c-e4bc-43b6-993f-fd140b6db7bd none swap sw 0 0
and I added different things like the following:
/dev/cdrom /mnt/cdrom iso9660 noauto,ro 0 0
but none of them helped.
And finally
$ dmesg | grep cdrom
returns nothing.
I'm not very familiar with technical things, I just tried all the different things suggested by others. Any help would be appreciated.

There are nothing related to cdrom in lshw, but in the output there are some unclaimed things:
