DVD-rom only reads, doesn't write


Hello,

I have a Toshiba Satellite Pro 6100 laptop with DVD-ROM.
I can't get it to burn CD's, as the DVD-ROM is not recognized as a writing device. It reads CDs perfectly.

I've googled around and already tried changing permissions (using k3bsetup, and also manually) for cdrdao, cdrecord and such; adding myself to group "cdrom"; doing "chmod a+xrw hdc", and other permission tweaks, but nothing works.

Apparently this is an ATAPI device, could this be the problem?

Apart from this, as I salvaged the laptop from garbage at work (Windows completely broken and "not financially interesting" repairing it), I don't even know if it IS a writer in the first place... (It says DVD-ROM, does this mean it's only to read?)

I installed PCLinuxOS 2007 (kernel 2.6.18.8.tex5), updated last week with synaptic.

The PCLinuxOS control center gives following information:
Code:

Disk identifier: ‎HL-DT-STDVD-ROM GDR8081N

Media class: ‎cdrom

Starting K3B from terminal (as root), gives following messages:

Any hints or ideas would be greatly appreciated. I'm not very newbie, but far from an expert, so my hand should be held anyway

Many thanks in advance.

DVD-ROM means it is a reader and not a writer (Read Only Memory). A quick Google on the model number reported (GDR8081N) confirms this.

So the drive can't write to either DVD or CD, it is read-only.

Thanks very much, and sorry for my ignorance - which just lessened a tiny bit
