growisofs fails part-way through writing to DVD-R

Hi.

I am trying to write the Slack 14.1 to a DVD but the process is not going well (I've made lots of coasters).

At first I was using K3B but was getting an error about not being able to fixate the disc. So I tried calling growisofs directly. Here is the log that printed to my screen.

Code:

$ growisofs -dvd-compat -Z /dev/sr0=slackware64-14.1-install-dvd.iso

Executing 'builtin_dd if=slackware64-14.1-install-dvd.iso of=/dev/sr0 obs=32k seek=0'

/dev/sr0: "Current Write Speed" is 8.2x1352KBps.

Here are some other things that may be of interest. It never fails in the same place. I am running this on a Lenovo t520 running Slack 13.37 (64 bit). I have written on this computer before. If I try writing to a DVD-RW I get no errors, but also the disc still appears blank after completion.

Let me know what else you need to help figure this out and I'll happily provide it.

Thanks.

Don't really know how to solve your problem, but this caught my attention:

Current Write Speed" is 8.2x1352KBps

I've always burned .isos to CD-R or DVD-R successfully at the slowest speed, usually 4x.

Did you check the MD5 of that iso before trying?

Have the DVD-Rs that you are using possibly been exposed to extreme temperature, or possibly just bad?

Finally, I have experienced something similar when a CD/DVD-RW drive was failing, maybe try on another box if MD5 is good.

I tried -speed=4 and it still failed.

So as far as quick things, that leaves the drive itself.

Writing optical media is sensitive to write speed and buffer size, is it possible that the machine is doing something CPU or memory intensive while you are writing?

Could be a bad drive. Try a different batch of disks, if it still fails get a new drive.

As this is a laptop, I'm not sure a new drive is really an option. I will see about different discs, but I don't have any others at the moment.

Unfortunately, I would agree it is likely a bad drive. FWIW, I have never had an RW drive survive more than a year or two on any laptop - including the one I am writing from. It doesn't seem to matter whether it is used a little or a lot... just age. I have come to expect them to fail quickly on laptops, desktop internal drives are almost as bad. It just seems to be a flaky technology IMO.

The only thing that you can do is look at the little worm drive gear if it is visible and make sure there are no dust-bunnies wrapped around it. And maybe blow any dust off the led lens, carefully - I have had both of those work for a while before.

But, if you have another system with an RW drive, you should try to at least confirm that the discs themselves are OK. As suggested above, try one from another batch if possible as well.

Thanks. I will try blasting it with canned air. Unfortunately, my windoze box does not recognize its drive as a writable media. :(

You can buy USB DVD+-RW drives. That's what I use for my netbook. Either the batch of disks is bad or the drive is bad.

Here is some new information.

I got a colleague at work to burn my iso and gave him one of the discs I had been using on my laptop.

The slowest he was "allowed" to burn the disc was at 8X speed. Could the types of errors I was having result from not being able to write at the minimum speed the disc is rated for?
