[SOLVED]new mounting routine for cdrom?

I don't seem to be able to mount my cdrom devices any longer (not machine specific). The error message is:

[thea@habicht ~]$ sudo mount /dev/cdrom /media/cd

mount: /dev/sr0 is write-protected, mounting read-only

mount: /dev/sr0: can't read superblock

My fstab file is:
<script src="http://pastebin.com/embed_js.php?i=4aZR7H80"></script>

Device sr0 is apparently not write-protected:

brw-rw----+  1 root optical  11,   0 Dec 25 11:50 sr0

I do not use my cd devices often, so it is possible I missed something in recent updates. In any event have not made any cd-related changes since the last time I used them, when they worked fine.

Thanks and merry Christmas!

Sorry -- looks like I don't know how to embed longer code sections either. The relevant line in my fstab file is:

/dev/sr0       /media/cd     auto      ro,user,noauto,unhide   0      0

Re: [SOLVED]new mounting routine for cdrom?

You cannot write to an optical disk as you can to a flashdrive (use 'cp', 'mv' etc.), you have to use a CD/DVD burner (like cdrecord), right? Your fstab clearly says 'ro' - read only.

Use '-o ro' to get rid of the first warning:

$ sudo mount -o ro /dev/cdrom /media/cd

I don't know why are you getting

mount: /dev/sr0: can't read superblock
