DVD-RW drive acting really strange

[Rogue Jedi X]

Sorry for the very vague description of the problem, I'll try to put it as simply as possible. This problem occured after installing Feisty.

My DVD-RW drive is a Sony DW-Q30A. I also have a TEAC CD-W524E CD-RW drive, which works fine. Like I said, the problem is my Sony DVD-RW drive. I've tried reading a video DVD (yes, I did install libdvdcss2 from medibuntu), a game DVD and a DVD my friend burnt for me using Nero, but it can't read any of them.
Oddly enough, when I tried to mount the aforementioned video DVD again, the file structure came up in Konq, but Kaffeine still couldn't do squat.
Next, I've tried mounting the stupid thing via console, which came up with:

sudo mount /dev/scd0
mount: block device /dev/scd0 is write-protected, mounting read-only
mount: Not a directory

So now I'm stumped. Here's my fstab, if it helps:

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options>   <dump> <pass>
proc      /proc     proc  defaults    0   0

/dev/scd1   /media/cdrom1 udf,iso9660 user,noauto  0   0
/dev/fd0    /media/floppy0 auto  rw,user,noauto 0   0

Sorry for the trouble and thanks in advance!

/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0

How about rw,user,noauto (instead of "user,noauto" only)?

Re: DVD-RW drive acting really strange

Tried altering fstab like you said, but still no dice. It gives me the same error message.

It gives me the same error message.

Hmmm ... what does [sudo] ls -l /dev/scd* tell us, then?

Re: DVD-RW drive acting really strange

It gives me:

roguejedix@rogga-alpha:~$ sudo ls -l /dev/scd*
Password:
brw-rw---- 1 root cdrom 11, 0 2007-04-25 13:42 /dev/scd0
brw-rw---- 1 root cdrom 11, 1 2007-04-25 13:42 /dev/scd1

Also, while looking around the forum and stumbling upon this post, I've discovered that the Mounting tab is dimmed, regardless of whether I access it as myself or root. Could this be related?

Badly enough, this looks good ... mumble, mumble ... what about [sudo] ls -l /media then?

Re: DVD-RW drive acting really strange

That gives:

roguejedix@rogga-alpha:~$ sudo ls -l /media
total 20
lrwxrwxrwx 1 root root    6 2007-04-21 23:40 cdrom -> cdrom0

drwxr-xr-x 2 root root  4096 2007-04-21 23:40 cdrom1
lrwxrwxrwx 1 root root    7 2007-04-21 23:40 floppy -> floppy0
drwxr-xr-x 2 root root  4096 2007-04-21 23:40 floppy0
dr-xr-x--- 1 root plugdev 8192 2007-04-21 10:49 sda1

By the by, is it normal that everything in fstab went from hd# to scd# or sd# ? Just occured to me.

Re: DVD-RW drive acting really strange

Yeah, that happened during the upgrade to Feisty. It's pretty confusing, and the effects of that are what cause 95% of drive problems immediately after the upgrade.

Just want to make sure, you are a member of the cdrom group, correct?

Re: DVD-RW drive acting really strange

drwxr-xr-x 2 root root 4096 2007-04-21 23:40 cdrom0
drwxr-xr-x 2 root root 4096 2007-04-21 23:40 cdrom1

Isn't that interesting, for "r-x" means nothing else than "write-protected" you may adjust that (with nothing mounted there), e.g. by sudo chmod +w /media/cdrom*, to "rwx" - and hope for the best ...

@SheeEttin
That's a relief. And yes, I do belong to the cdrom group, just checked.

@UnicornRider
Tried it and nothing. Also, out of curiosity, I tried burning a blank DVD with K3B, which my drive succesfully ruined. I can't say for sure, but I think it just wrote the Lead-In, then K3B spewed out an error message.
