(note: I don't know in which StackExchange site to put this question, I'll thank the moderator that will move it to a more appropriate place, if there is a S.E. available for my question).

I have a DVD RW drive that is well listed in the bios, and if no CD is in, it is also present in the "My Computer" of my Fedora 16.

But when I put a disc on it, the icon disapear from "My Computer", and I can not do anything with this ! (Like erasing a RW disc).

I'd like to boot a Fedora 17 Live CD image. I burned it on an other computer but when I try to run it in bios, nothing is done and I'm redirected to Grub of my HD.

The command cdrecord -scanbus shows this :

wodim: Warning: controller returns wrong size for CD capabilities page.
wodim: Cannot get CD capabilities data.
    6,1,0   601) 'HD-DT%ST' 'DVD%RAM G@22NP20' '1&04' Removable CD-ROM

And when I try to mount manually the disc, I got this error :

mount: block device /dev/sr0 is write-protected, mounting read-only
mount: /dev/sr0: can't read superblock

Here's a paste of dmesg | grep sr0 :

The lines from Sense Key .. (line 6) to DRIVER_SENSE (line 11) are repeating a lot.

I then changed my DVD player with an other spare one I had, and the disc didn't boot neither. I then changed the IDE cable, but still no success.

What can I do to make it work? Thanks for your help.
