PIONEER DVD-RW DVRTD08 is disabled if there is no disc present at boot time

[linux-ide]

Hello,
several Sony Vaio laptops seem to have the PIONEER DVD-RW DVRTD08 DVD/CD
drive built in. This drive is available only when a disc is inserted
during boot.
when no disc is present, dmesg has

Having read http://www.mail-archive.com/linux-ide@vger.kernel.org/msg06127.html I guess it is not OK for the device to timeout in response to 0xef.
Still I would like to be able to use the drive without having to insert a CD at every boot. Is there any workaround? Can't the driver just treat
repeated timeouts like it would treat an abort?

Any help would be greatly appreciated.

That case was a bit different in that it was a CompactFlash device 
(which has some different rules, especially older ones), but there was 
also a SATA-PATA bridge chip involved (which seems quite likely the case 
here too since the drive reports UDMA33 maximum). This could be another 
case of the bridge chip being broken. Set Features - Set Transfer Mode 
is a mandatory command that all ATA devices must implement, and the 
device really can't be used properly if it's not successful (for true 
SATA devices it's mostly vestigial, but if there's any actual PATA 
involved, it's required). It's rather bizarre that having a disc 
inserted avoids the problem.

Is there any firmware update available for the drive?

Aiee... these broken devices.  :-(

So, w/ a disk inserted, there's no error whatsoever?  Can you please
post the output of "hdparm -I /dev/sr0"?

I've had a look on the Pioneer Website but I didn't find a firmware
update that was explicitly meant for this drive. I contacted
kenichi_tokudome@post.pioneer.co.jp who is listed at
http://www.serialata.org/integratorlist12.asp as the Pioneer contact for
that drive asking him about the problem and whether a firmware update
was available, but I have not yet received a reply, yet.

There's no error in dmesg output. But when I boot with a disk in the
drive, I get the following errors in the boot screen:
* Loading hardware devices
[23.927373] end_request: I/O error, dev sr0, sector 1431744
[23.927373] Buffer I/O error on device sr0, logical block 178968
and then several more with just a different number in the square
brackets. However, that does not seem to affect the operation of the
drive.

Does the attached patch fix the problem?  Please do some data
integrity checks as it skips setxfermode on the drive.  If it's native
SATA, it probably should be okay but still it's way out of the spec.

Thanks.

Re: PIONEER DVD-RW DVRTD08 is disabled if there is no disc present at boot time

[linux-ide]

Hello,
I've tried the patch (thanks a lot for your help) and it works more or
less. 

More precisely:
when booting without a CD in the drive:
* no errors during the boot
* the drive is now active (that's a big plus)
* it can read about half the CDs that I insert (in a sample of ~7 audio
and data, burnt and pressed), I have tested no DVDs yet, and I haven't
burnt anything yet
* sudo hdparm -I /dev/sr0 now gives

* When booting with a CD that doesn't work after an 'empty boot', I get
similar errors as before (and like the last pair of lines above), but
the CD can be read. When I insert another CD that didn't work after an
empty boot afterwards, it still doesn't work.

I guess that this is a state of things I can more or less live with
(unless you have a still better idea), I don't know whether the patch
should go in the trunk. Though it doesn't completely fix things, for me
it's better than before. Obviously, it would be best if the Pioneer
people fixed their broken firmware soon, which I hope they will.

Anyway, thank you very much for your help. With other OSs it's probably
not so easy to get developer support ;-)

Merry christmas,
Moritz

Those errors shouldn't have much to do with how the transport is
configured.  These are the drive failing to read the media and these
errors can be quite indetermininstic, so it's possible that the
pattern really isn't a pattern but then again the drive doesn't seem
to have much problem being peculiar.  Can you please test more times
and verify the pattern?

As the behavior is so peculiar, one thing I'm worried about is whether
the problem is common to the model or is specific to the drive.  If
the former, it should go into mainline.  Do you happen to know anyone
who has the same model?

I have randomly tested a few CDs and DVDs since my last post, and there
were none that didn't work (after an "empty boot"). Since I found all
those that did not work before at my parents' there is a chance that
those CDs were not in the best of states. I will be far from a computer
during the next couple of days. But afterwards I plan to do some more
systematic tests, and I will also attempt to burn a CD and a DVD.

The basic problem seems to be common to the model (or at least to more
than just my drive) since there are several posts by other people:
http://ubuntuforums.org/showthread.php?t=986871
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/299865
None of them has a solution or workaround. I think I had found more
reports before this thread started to dominate the search engine results
on the issue. As far as I see your patch skips setxfer only after a
failed first try. That should prevent it from affecting drives that
don't show the problem.

Happy New Year,

Moritz

These errors remind me of this Ubuntu 8.10 bug:

https://bugs.launchpad.net/ubuntu/+bug/295795

This bug only shows up on discs burnt with Brasero, never on discs burnt 
with K3b.

Hi, I have successfully burnt several Video-DVDs (with growisofs; on
DVD-R and DVD+RW media), an Audio-CD (brasero) and a Data-CD (brasero).
Also, I have not experienced any more problems reading CDs or DVDs. I
guess that the CDs that did not work after I applied the patch were
damaged.
Therefore, I tend to regard the problem as fixed by tejun's patch and I
would recommend to let it go into mainline.
Thank you once more for your valuable help.
Moritz
