:-[ SYNCHRONOUS FLUSH CACHE failed with SK=8h/ASC=00h/ACQ=00h]: Input/output error

[Luis Mondesi]

Binary package hint: dvd+rw-tools

Lately (Ubuntu Edgy), I have been getting these errors when burning DVDs to my Pioneer (8x8) DVD+RW drive. Note that the disks work on some players even after this happens (on an Apple iMac). However, if I insert the disk back in my system, I get presented with a dialog that says that I have inserted a blank DVD and if I want to make a new disk.

I think that what's happening is that the disk is not properly closed. How do I fix this?

This bug is very similar to this on the Debian BTS:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=392778

But I'm reporting it here because this is a different version of Growisofs
$> growisofs --version
* growisofs by <email address hidden>, version 6.1,
  front-ending to mkisofs: mkisofs 2.01.01a03-unofficial-iconv (i686-pc-linux-gnu)

Hi,
I've the same error.
How to resolve it?
Thank's.

That generally means that either a controller in your system is buggy or bad
or your disks are dying.

Try installing smartmontools and do extensive testing on the media in
question. If it is a hard drive, of course. If you are talking about a CD
burner or a DVD, or any removable drive, then you might want to remove that
from your system and put it in another system and see if it's the device
that it's bad or if it is your motherboard that it's bad.

Updating your BIOS should work, if the motherboard of your system has an
older BIOS.

I forgot to add that after changing the motherboard of my system I have not seen this error anymore.

What program(s) did you use to burn dvds? What motherboard/chipset did you have when you had these problems, and what do you have now?

This bug has all the signs of being a hardware issue and not necessarily one with Ubuntu. For the moment I am closing it out, if you feel that this is in error or someone can reproduce the issue, please re-open.

   Thanks,
