Question Lost ability to see or burn blank DVDs


Fedora 11. Sony DVD RW burner.

Inserting a blank DVD gives "no medium found" in dvdrecord and all related utilities. No icon shows on desktop. The device shows up.
Code:
$cdrecord -scanbus
scsibus4:
	4,0,0	400) 'SONY    ' 'DVD-ROM DDU1612 ' 'DYS1' Removable CD-ROM
	4,1,0	401) 'SONY    ' 'DVD RW DW-U18A  ' 'UYS1' Removable CD-ROM
	4,2,0	402) *
	4,3,0	403) *
	4,4,0	404) *
	4,5,0	405) *
	4,6,0	406) *
	4,7,0	407) *
Burned DVDs and all CDs (burned or blank) show up normally.

Help?

dvd+rw-mediainfo /dev/hdd

What's the output of this command? Of course replace "/dev/hdd" with the device for the drive.

Probably not enlightening.
Code:
dvd+rw-mediainfo /dev/sr1
INQUIRY:                [SONY    ][DVD RW DW-U18A  ][UYS1]
GET [CURRENT] CONFIGURATION:
:-( no media mounted, exiting...
In reality, a blank DVD-R is in the drive. (Several different discs from different manufacturers tested; same result.)

maybe I'm missing the point, but blank media isn't going to show up as anything. Because it's BLANK. You can't mount it, it doesn't have anything on it. You can't play it, it doesn't have anything on it. What are you expecting? All blank media to have a magic copy of lord of the rings on it?

Generally I agree.

But (there's always a 'but') I remember on my Slack11 configuration, depending on how I had set the KDE media notifier settings in KDE's control-center, it would actually pop up a dialog telling me "Blank Disc detected" or something like this.

However, again I pretty much agree, that without a similar media detecting daemon (or HAL these days??) you really aren't going to detect very much, when a blank disk is inserted.

What if you put a blank disc in the unit, and try to burn something to it? What happens? Please provide console output, messages, errors, etc. And, does the drive work correctly when a NON-blank media is inserted?

Excuse me, but Fedora generally (a) pops up an alert that a blank disk is inserted and what do you want to do with it; (b) shows an icon labeled Blank DVD on the Desktop; (c) allows you to burn with Brasero, K3B, or command-line tools. None of which works in this case. I wasn't expecting Lord of the Rings and your condescension is matched by your ignorance.

Here is what happens with dvdrecord.
Code:
dvdrecord dev=/dev/sr1 ~/Download/Fedora-11-x86_64-DVD.iso 
dvdrecord: No write mode specified.
dvdrecord: Asuming -tao mode.
dvdrecord: Future versions of wodim may have different drive dependent defaults.

growisofs -speed=2 -dvd-compat -Z /dev/sr1=imagefile.iso

If you would kindly try out the above command, substituting "imagefile.iso" with the name of your .ISO file, and see what that does? You'll need to be root to do this.

I have a similarly identified SCSI burner to yours, and this works for me.

Failing the above, I would next suspect that the media is incompatible with the drive (yes, it can happen unfortunately).

PS - I notice that your drive does not claim to support DAO mode (disk-at-once) -- I don't know if this is relevant, but let's keep it in mind in case it does become relevant later. You might need to force another mode, if it tries to use DAO.

Best of luck,
Sasha

Yes, but when dvd+rw-mediainfo is run, it should tell you that there is a blank disc in the drive, it's indicating that the drive's empty.

I'd believe the DVD is incompatible except the drive has rejected at least three different manufacturers. Moreover, it will read the same DVD if it is burned on another machine.

I'm almost out of options, however I'll make one more query:

How old is the drive? And further to that, if it's older than say a couple years, and potentially has seen dust, smoke, and other pollutants in the environment, maybe cleaning it would help? Cleaning optical drive lenses has done wonders for me in the past. But, if the drive is *very* old, well, maybe it's time to simply replace it. Sometimes they just 'pack it in' and that's that.

And, excuse me if you mentioned it above (I don't see it anywhere) but when was the last time the drive worked "properly" with regards to blank DVD's? Like, was it a week ago, a year ago, or...

Thanks for your patience,
Sasha

I have experienced the same problem after a rootkit attack. When I ls -la /var/log/ my laptops hardware went haywire - at least all the USB devices. DoD format and reinstall, everything works fine now except the dvd burner. The hacker was not at all subtle and was out to do damage. I had burned DVD's from the same pack of Sony disks on this burner before, but now have same problem as drlaz. The burner is detected by the system (lsusb), but won't detect either blank DVD's of various types or media with files on it. Tried unplugging and replugging, cables, on/off, attached on boot or not attached.

Will try growisofs -speed=2 -dvd-compat -Z /dev/sr1=imagefile.iso
and also check if all the relevant software is installed.

Cheers

Of of course I'm ignorant of what fedora does. I run debian. When I insert a blank disk, dbus/hal/avahi shows a message on the root terminal. That's what I use to indicate that it's time to push enter on my next to be burned disc. Granted that I don't normally run with dbus+hal+friends most of the time. Fewer apps running equals fewer memory leaks, and generally more resources available for other tasks. And if you're the paranoid type, fewer security risks. (why does gconf-2 stay up after I've closed the apps that use it?) (why does pornview an image viewer access the internet when I launch it?)

Anyway, DVD drives do burn out. Or at a minimum get dirty and need to be cleaned to ensure that the laser can do it's job. Since you can still read content (if it exists) you're not at critical mass yet. But there's some sort of issue (yours, not mine). Could be hardware, could be software. If nothing changed software wise, then perhaps something else changed. Was there an upgrade involved in this change of behavior? Did the power go out? Is it thursday and raining (oh wait, that's an M$-ism).

The drive appears to be working again. Besides the possibility that some speck of dust moved, there are two possible explanations. Well, that I can think of. First, I do sudo yum update daily; perhaps it was a software issue. And second, I swapped the Ethernet cable because I was dropping off and then reconnecting to the LAN frequently.

Of those two options, I would eliminate (2) right off the bat; ethernet has nothing to do with the situation.

The first option though, the software issue, that's definitely a possibility. If you want to pursue it, it'd be prudent to identify exactly what packages have been updated between the trouble and the solution.

Cheers!
