Powertop has left me with a rather odd problem. After making a change involving my DVD-ROM drive's power useage, my drive no longer works in Ubuntu. I think it's no longer loading the driver correctly. The error message says "Cannot mount volume." Details say:

mount: block device /dev/scd0 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/scd0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg|tail or so

So I tried that, but dmesg|tail gives me this:

Really? Nobody knows how to fix this? I was hoping it was something simple, but I've been trying to get this thing fixed for days.

If anyone can just point me in the right direction for DVD-ROM configuration under Linux, that would be great.

ok let's start somewhere.

Can you please post the output of these commands:


sudo lshw -C disk
cat /etc/fstab

Sure thing, and thanks for responding.

sudo lshw -C disk gives me:

Thanks for the tip, I'll give it a try. It's been really, really hard to get anyone to help me with this, and I've tried in multiple places. My previous ubuntu/linux issues have been resolved in like record time, I guess I got spoiled. :)

I just hope it didnt go sour, I had a DVD ROM drive that just decided to die without reason.

I don't think it died, but the current settings in my fstab don't match what's referred to in that thread at all. Here's what I've got:


UUID=2a17f341-2418-4639-8841-eb6e10e5d712 none swap sw 0 0
/dev/hdc /media/cdrom0 udf,iso9660 user,noauto,exec 0 0

Is there a different way I should approach this?
