[SOLVED] K3B hates USB Burners

[linuxero]

Hi folks;

I have been trying to get a solution on several forums. Nothing could help out!

My K3B would never permit me to burn on a USB Burner I have attached two pics to show you what K3B configuration's like.

Hope someone could give me a hint.

PS. I already added my user to cdrom and cdwriter groups..!

[doktor5000]

OK, but where's the actual problem? I see no error message, and the setup dialog is not needed at all, also no special groups.
I've got an external burner running fine with Mageia 1 here, out of the box. Just plug and burn.

What also seems strange is "Capacidades de grabación: Error" in second screenshot, seems it can't even
get the information about supported media which it can write to. You're sure that thing is not broken? When did you use it last time, and how old is it?


On a related note: As the official language here is english, it would be really nice if you post error messages/output in english.
For that, you can prefix the command you want to start with

Code: Select all

LC_ALL=C

Thanks in advance.

Not to me, the /dev/sr1 device is denoted as a DVD-ROM so it should not be able to write , there should be better appear a "n/a" than "Error".
But I've also no idea for the actual problem.

Well, that's actually only a string which the software reads, this has pretty much no physical corelation to do with the drives ability to write

[alf]

But you know that there are read-only devices which are denoted as DVD-ROM, I admit not commonly these days, but I've also such a device and k3b reports an error reading the writing capabilities. It's a blur in k3b I think.

[doktor5000]

Well, would be natural to not be able to detect write-capabilities on a DVD Read-Only-Memory, i'd also error out on that

[alf]

Well, I really mean the device, not the media inserted. And if I look at the initial post it seems to be that linuxero tries to burn with the DVD-ROM device instead the DVD-RW device.

[doktor5000]

Let's wait until he replies. I take it as a given, that if he says it's an external usb burner, that this is the case,
as the LG drive is definitely an internal one. Also most DVD-ROM drives won't read DVD+RW, so i'd say this is a malfunctioning external burner,
judging by a short search it's a slim burner, usb-powered.

@linuero: How is it attached to your box, with an y-type usb cable, so that it gets enough power?

[alf]

Have a look here, can only read but not write DVD
Didn't find the model mentioned in the post but seems to be a similar model.

[Ken-Bergen]

What I find odd and likely the source of the problem is that the internal Laptop drive is listed as /dev/sr1 and the LG internal drive in an external enclosure is listed as /dev/sr0.

[linuxero]

Thank you all;

Let me put the problem differently..

First of all, I am having this problem for years now with all the distros I work with. However; I am always using these external burners in Windows and they work seamlessly.

So; this burner was an internal one of a laptop that I took out and put in a case to connect it externally through usb.

It is a DVD writer, of course it is capable of burning cd's too. I wonder why K3b detects it as DVD-ROM! But in the second snap-shot you can see that DVD+RW is there..

Last time I used it..well I am using it all the time. That what troubles me,though, is that I need to use it under Windows, which I almost only switch on for this trivial problem..!

The LG is an internal one on this machine so it is sr0. But I would never ever recommend LG. This is the third LG that gives me problems on many discs.

I tried several other burners, desktop and laptop ones, using an adapter to connect externally, but under Linux I am always having this problem.

As for the errors in English, I always try my best, but in a GUI how am I supposed to switch it?

[goofball]

Hi,

As for the errors in English, I always try my best, but in a GUI how am I supposed to switch it?

you need to open the program from a console.

For example you can open Konsole (or any other terminal program) in KDE and enter

Code: Select all

LC_ALL=C k3b

to start K3B with an English user interface.

HTH,

goofball

[linuxero]

Nice trick, thanks Just was wondering about all gui stuff, no terminal, though!

@goofball: Hey there, long time no see

That's an odd configuration that i doubt anyone but you has tried.

The DV-28E-C is as alf said a read only device. If MCC > Local disks reports it as such it's a hardware detection issue not a K3B issue.

You could and should make a bug report listing what it's seen as and what it actually is as well as the fact that it's being used as external USB drive.

[martinw]

I think I've seen this problem before. If so, the problem is that the device identification string read back from your external device is "DVD-ROM DV-28E-C". IIRC, K3b (or one of the underlying tools it uses) scans this string, and if it finds "ROM", assumes the device is read-only. I believe I found a way to override this behaviour, but it was a long time ago. As I don't have K3b or the old CD writer that exhibited this problem installed, I can't easily check my recollection.

Guys; it's not read-only!! Besides, supposing it is read-only for DVD's, and it is not, why shouldn't K3B be able to burn CD'd using it?!

linuxero: please read my preceding post again. I'm not saying the drive is read-only; I'm saying the software is fooled into thinking it's read-only, because of the text string it returns to describe itself.

If i look at the product specifications it is a read-only devices. Can't believe you have ever burned any DVD/CD with this model. But if I'm wrong look at the mount options maybe the device is read-only mounted.

Alf will you please remove your double-posting.
Thanks in advance!!!

[sglafata]

I believe martinw is heading in the right direction for root cause of the issue, but I was wondering if the "new permissions" in the first picture has anything to do with the problem linuxero is having?

[doktor5000]

The new permissions only come from k3bsetup, which tries to adjust the permissions, and there it was only done for one drive.
As long as the drive is recognized as DVD-ROM, the permissions can be changed to what you want, that won't solve the problem AFAICT.

Thanks a million..pass by me some weekend and get a blank DVD ready!

[Ken-Bergen]

So far you've only told us what Linux thinks the drive is.
Until you tell us what it actually is no one can help you.

I told you before that I have taken it from a laptop and bought the case, which you can see in the attached shots..

Should I take it out and send more shots of it!?

Thank you all
