DVD writer and IDE support...

[aeriksson]

All,

I've just gotten myself a new DVD burner which triggers some 
interesting events in the kernel. From the log:

hdc: ATAPI 48X DVD-ROM DVD-R CD-R/RW drive, 2048kB Cache, UDMA(33)
Uniform CD-ROM driver Revision: 3.20
hdc: packet command error: status=0x51 { DriveReady SeekComplete Error }
hdc: packet command error: error=0x40 { LastFailedSense=0x04 }
ide: failed opcode was: unknown
ATAPI device hdc:
  Error: Hardware error -- (Sense key=0x04)
  Focus servo failure -- (asc=0x09, ascq=0x02)
  The failed "Read Cd/Dvd Capacity" packet command was: 
  "25 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 "


rmmod'ing the icd-cd module and modprob'ing the ide-scsi (seeing as 
that used to be the common approach for folks (I'm new to burners...))
I got this in the log:

ide-scsi is deprecated for cd burning! Use ide-cd and give dev=/dev/hdX as device
scsi0 : SCSI host adapter emulation for IDE ATAPI devices
  Vendor: AOPEN     Model: DUW1608/ARR       Rev: A060
  Type:   CD-ROM                             ANSI SCSI revision: 02
sr0: scsi3-mmc drive: 48x/48x writer cd/rw xa/form2 cdda tray
Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0

How should I interprete this? That the device is not supported under
the icd-cd module but the scsi support detects and supports it ok?
I've not tried to burn anything with it yet so I have no hard facts on
if there is enough support (yet).

If there is any sort of data which need to be shipped somewhere to 
make this device supported by ide-cd, I'd be glad to help...

Advice appreciated,

/Anders

Well certainly something appears to go wrong.  So far I have used a dvd
writer (PX708A and PX716A) on kernels up to 2.6.10 (i386) and 2.6.11
(amd64) and had no problems using ide-cd to do the burning (writing
DVDs using growisofs of course, and CDs using cdrecord).

Well it does look odd that it loads with one and not the other.  Which
kernel is this with?

Does writing CDs and DVDs actually work using ide-scsi?  Does it work
using ide-cd?

Dunno yet. What's the fastest way to dump a file to a (fs on) a blank 
4.7 GB DVD RW? As I said this is not my home turf so I have to read 
up on the commands to use (I guess I'm not dd'ing an iso image to 
/dev/hdc...)

Probably close to the 2.6.11 kernel I run on Debian-pure64/sarge.

growisofs -Z /dev/hdc -J -R /path/to/dir/with/less/than/4.5GB/of/files

That should do it.  To do scsi I suspect it would be /dev/sg0 or
/dev/scd0.  I haven't actually tried burning in scsi emulation mode with
these drives.

growisofs is part of dvd+rw-tools.  It will autoformat the disc if
needed.

Nope. No go. The kernel log getsb these 4 lines:
Apr 13 22:08:30 tippex SCSI error : <0 0 0 0> return code = 0x8000002
Apr 13 22:08:30 tippex sr0: Current: sense key: Medium Error

Apr 13 22:08:36 tippex sr0: Current: sense key: Medium Error

and the application bails out with:
:-[ WRITE@LBA=0h failed with SK=5h/ASC=30h/ACQ=05h]: Wrong medium type
:-( media is not formatted or unsupported.
:-( write failed: Wrong medium type

This is with a fresh from the box DVD-RW. Do I need to 'format' the
thing before writing to it? This is getting tricky... Are these kind
of errors normally indicative of lack of support or a faulty unit?
I have no windows around to test it with the shipped nero-cd :-(

What brand/model drive is this?

It is possible to get very weird errors if you have unsupported media in
the drive and some drives don't like certain media types.  Sometimes a
firmware update on the drive fixes it although it usually requires
windows (or sometimes dos) to install the update (or linux will do if
the drive is a plextor).

Should I consider changing it? (I got an 'if this doesn't run on Linux 
I can trade it in' warranty at the shop)

Well there is a cdwrite mailing list hosted on lists.debian.org which is
a great place to figure out what weird errors are and such, and the
authors of the programs used for writing discs are on thoses lists too,
so you may want to ask for advice there.

Did you try writing using ide-scsi mode with growisofs ?  Any
difference?  Does dvd+rw-media return anything with a disc in the drive?

It might require windows.  Certainly their firmware updates mostly seem
to cover 'improved media coverage'.

I have only been buying the plextor drives personally, since I have
never had a problem with a plextor drive yet, and I like not needing
windows to update the firmware and I find I save time by spending a bit
more on getting the best hardware I can reasonably afford.

I just thought I should chime in because I have the same burner running
under a 2.6.11 kernel, and using ide-cd. The drive burns just fine, linux
support was good, but I did run into two problems:
1) I had to shop around till I found a brand of DVD-R (I haven't tried RW yet)
    that would work, finally settled on TDK.
2) it failed to write to slower media, I think anything below 4 it had
trouble with

So it is a very picky drive, or the firmware is still in need of fixes
(I saw at least 4 firmware updates each adding improved media
compatibility, so perhaps it is something they are working on).

Perhaps not the best writer around, but I bet the price is nice.

Thanks for that info! I'm starting to suspect media too. I'll try to 
wreste that firmware upgrade into it. Which firmware version are you 
using?

I've got version R1.07 of the firmware.

Through a very painful procedure I got w98 installed and bumped my 
firmware revision. The filename of the installation binary was 
duw1608_r108.exe suggesting R1.08 but the windows screen mentioned
that the bumping was from 060 to 080 or thereabouts...

At any rate, now everything seems to work as it should, using the 
ide-cd driver. That you all for the help!

Sounds like you had 1.06 and went to 1.08 and that solved the problem.
Always nice when companies fix their firmware bugs. :)

Yep. I get the feeling my media and the drive as-is don't like each
other. What are the chances that the device is faulty but i can still 
blank the media (btw where can I read up on blanking vs. formating?)

And so does that.

Maybe try growisofs -dvd-compat -dvd-compat -Z /dev/sr0 .... like it suggested.
Maybe the drive's firmware doesn't support the modes normally expected
by growisofs.

growisofs has some odd options in the source code, and the authors on
the cdwrite list may be able to help.  I think it is starting to look
like bad firmware or a defective drive.

Well I am not sure it's the media either.  I think the drive isn't quite
up to the specs growisofs expects.  The authors may be better able to
answer that.  They also have some tools they may ask you to run to ask
the drive what features it has so they can see if the drive is a bit odd
or not.

> Starting to seem like a wise choice...

I got the PX716A a few weeks ago while they had a $30 mail in rebate.
Made it not much more than buying a lesser drive.  Unfortuantely that
expired at the end of March.

On the other hand, not having to run around trying weird things,
wondering if my media is bad, I just burn discs.  Sometimes it burns 8x
media at 2x if it doesn't think they are high enough quality, but it
burns them right each time.
