DVD ROM is not working

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.

I tried a driver CD from Logitech to see if it was working, here's the dmesg log :

[91262.960539] sr0: CDROM (ioctl) error, command: Xdread, Read track info 52 01 00 00 00 01 00 00 20 00
[91262.960561] sr: Sense Key : Hardware Error [current] 
[91262.960570] sr: Add. Sense: No additional sense information

I then tried with an old game CD (for windows), here's the result :

[91372.015116] sr0: CDROM (ioctl) error, command: Xdread, Read track info 52 01 00 00 00 01 00 00 20 00
[91372.015138] sr: Sense Key : Hardware Error [current] 
[91372.015147] sr: Add. Sense: No additional sense information

(same error)

If I try to mount it (linux : mount /dev/sr0 /mnt/cdrom/), here's what dmesg says :

[94083.825753] sr 6:0:1:0: [sr0] CDB: Read(10): 28 00 00 00 00 10 00 00 01 00

My driver is a LG GH22NP20BB.

Update 1 :

I tried again with an other DVD driver, here's the dmesg :

[  343.828326] sr0: CDROM (ioctl) error, command: Xdread, Read track info 52 01 00 00 00 01 00 00 20 00
[  343.828349] sr: Sense Key : Hardware Error [current] 
[  343.828357] sr: Add. Sense: No additional sense information

Oh well, same error! So it's related to the mother board (that's all I can guess)

Could it be a wrong configured bios? (like sata/ide/raid something?)

Update 2:

I resetted my bios, and it didn't changed anything, so I think the problem is on the motherboard. I'll see with my manufacturer.

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

Answer 1

Since it looks like the problem is located on the mainboard the controller might be broken, so there is probably not much you can do. One last thing you could check is to see if there is something behind the connector on the mainboard that could cause shorts. Sometimes there are excessive brass spacers, that were not removed before the board was put in. In cases with poor quality the board carrier might also be bent so the board is touching it directly. Since even the drives's name does not come up correctly, it could also be some pin not being connected properly. So also make sure that no pins in the connector are bent and thus left unconnected. If the connector is dirty, some rubbing alcohol might help.

If there are no such problems (or there was one but removing it does not fix your problem) you have three options to keep the otherwise working board.

• use a drive with another connector like S-ATA or maybe USB (assuming such conector is available)
• use a ATA/S-ATA bridge to connect your drive to a S-ATA port on your mainboard (assuming there is one)
• use a separate ATA adapter on a PCI card (assuming there is an available PCI slot)

While the first option might be the most expensive, I would recommend it because it will just work. Using separate bridges or adapter cards might cause new trouble like not being able to boot or not supporting ATAPI devices.

Answer 2

Well, looking at what you've done so far, we can rule out that its the drive. There's two possible places issues can happen here. Firstly, the IDE port on the motherboard - but thats not likely, and a pain to fix. The other could be that the IDE cable itself has broken down over time - you may want to try swapping the cable to see if that helps.

Answer 3

I'd agree with your last assessment, sounds to me like its the IDE port on the motherboard that's broken down somehow. I'd suggest confirming this by connecting something else (maybe a HDD?) to that same port and see if it works.

Answer 4

Are you sure it's a CD? There are two competing DVD standards, and older drives can only read one of them. (DVD+R or DVD-R)
