Write problems with unbranded DVD[+-]RW drive...

2003-11-20 Thread MacArthur, Ian (UK)

Greetings all,

At the weekend I got an unbranded DVD writer - I was in a local electronics shop, it 
was on offer very cheap. I have *a lot* of data to archive, and it seems like a 
bargain...
Claims to support + and - RW writing. 
(The retail box is marked PIKA ONE, but the drive itself is unbranded.)

Installed the latest cdrtools from source. It's what I know, so it seemed sensible to 
stick with it, it's always worked well before...
Installed in place of my CD burner, burned some test CD's with cdrecord, all worked 
fine.
Installed Ogle and checked I could watch DVD's smoothly - worked fine.
Installed cdrecord-ProDVD test binary.

A test run -dummy went smoothly, but the actual burn failed (see sample failure below).
This is with Verbatim 4x DVD-R media, in case that matters.
Fiddled about with hdparm in case my DMA settings were a problem, no better.

Tests with dvdrecord fail in exactly the same fashion (and again the dummy run is 
good.)

(coaster count now at 4 and rising...)

However, tests with dvd+rw-tools (my 3rd scheme...!) have all worked perfectly, both 
with DVD-R and DVD+RW media, so I guess that basic drive is OK.
At least, I can read the disks it's written back on my Mac, so I guess that's OK!

Is it likely something in my setup that's upsetting the cdrecord derived tools? 
How do I pin this down and fix it?

Base system is linux, with a 2.4.16 kernel, latest cdrtools tarball... what else do we 
need to know?

TIA for input.

RE: Write problems with unbranded DVD[+-]RW drive...

2003-11-20 Thread MacArthur, Ian (UK)

Rob,

 Fiddled about with hdparm in case my DMA settings were a 
 problem, no better.
 
 
 I hope that means that you saw that DMA was on. You want DMA, 
 and if the 
 DMA doesn't come on by itself, it sometimes means it will 
 have problems 
 (my DVD-104 needed an update to 1.40 firmware before the DMA 
 defaulted 
 on at boot time).

Well, according to hdparm, DMA is not defaulting to on on this drive. But turing it on 
with hdparm seems to work (although my testing of this lacks rigour - i.e. run Ogle, 
watch how jerky it is, check CPU load. Turn DMA on, run Ogle - smoooth motion, lower 
CPU load...)

However, in my attempts to get the writing to work, I tested with DMA on and off, with 
broadly similar results. Indeed, (subjectively) writing seems *less* flaky with the 
DMA *off*. Which seems so wrong to me.

Also, most of the disks I have managed to burn with dvd+rw-tools have been with the 
DMA *off*. Well, I'm pretty sure it's off - not at that machine just now...


 
 While I have one + drive, I haven't tried + media in it, I find no 
 advantage in price or speed, and a backup is a backup, the DVD-R read 
 okay on more DVD-ROM drives I have, so that was the end of my 
 interest.

Well, I had the DVD+RW media anyway, and no -RW disks, so it made sense to test it.
Indeed, the Mac managed to read the +RW disks fine, and it has a DVD-drive in it (a 
Pioneer) so I guess that's all the compatability testing I need for this job!

 The write speed is interesting,  although what it means on a 
 fail is not obvious.

Yup. Asked for 1 - reported 4. But I think on a fail it probably isn't true?
Still, the drive and the media are both spec'd to support 4x writing, so that in 
itself shouldn't be an issue I guess, anyway.

Cheers,

Re: Why does cdrecord turn burnfree off by default?

2003-11-20 Thread Joerg Schilling
From: Samuel Tardieu [EMAIL PROTECTED]

The manpage of cdrecord says:

   The  default  is to turn BURN-Free off, regardless of the
   defaults of the drive.

What is the rationale for doing that? Shouldn't burn-free be turned on
by default, or at least be let untouched by cdrecord to preserve the writer's
default behaviour?

Its the SCSI standard. and CDs with Burnfree are of worse quality.

Leaving it untouched would cause cdrecord to behave unpredictable.

 There is a firware update to 1.03 for the Plextor 708A. I applied it on mine
 and it's Ok so far.
 -Dyson

I know of this, but according to what I read about it it did not
add too many new media. I would update if I did not have to
use DOS/Win for this. How did you do it? If you used a Linux
tool, I would be very interested in the details..

I just asked Plextor for the neexed info. Lets see what happens...

Pleased to hear that :)

I just sent a mail (see below) to [EMAIL PROTECTED]
Maybe some more people reading this list can send similar requests?
Not all of you have a Plextor, but you can duplicate and send to
other manufacturers too. Perhaps also to info@ addresses as potential
customers (that did not already buy, but would if Linux is supported..)
OK, that probably wont change much, but at least we have to try :)

FL

--- support request

Hello Plextor,

I purchased your DVD recorder model 708. I want to run it
with Linux. You link to some resources on your website
at page http://www.plextor.be/English/technical/linux.html

CDrecord does not at all work with the 708. I know this is
not primarily your responsibility, but I want to express my
request that you do everything to support the author.

There is another project named dvd+rw-tools, that currently
works in many cases with the drive:
http://fy.chalmers.se/~appro/linux/DVD+RW/
Perhaps you can add it to the Linux-page?

Another chapter is firmware updates. The author of cdrecord
also maintains a Linux flash utility, but it also does not
know the 708 yet. Again, please supply the author with all
necessary information or hardware as soon as possible.
The firmware itself is packed into an .exe - why dont you
use a standard format like zip? At least alternatively.

I am sure there are more users interested in recording on
Linux - please reconsider to increase your commitment
regarding Linux. If Plextor becomes the brand of choice
for Linux users, this is a target group that may be more
valuable than its pure number suggests. Maybe Plextor already
is better for Linux than many other brands - but it sure is
far from real good..
One thing is sure: the Linux community is growing. Multimedia
with Linux is gaining ground (mplayer, VDR). Lots of people
build their own HD+DVD-videorecorders on this basis.

Thanks for reading.
Your hopeful customer..

 Yup. Asked for 1 - reported 4. But I think on a fail it probably isn't true?
 Still, the drive and the media are both spec'd to support 4x writing, so that in 
 itself shouldn't be an issue I guess, anyway.

My experience with DMA is that having it off can seriously stuff the
kernel's time keeping, with the result that it needs 20min to advance 10min,
causing throughput rates to be displayed off by a factor of 2. This even
happens on recent 2GH P4 hardware.

If you want to find out actual writing speed reliably, you need to find out
how many bytes were transferred and take the time using your wrist watch.

In theory, writing over USB 1.1 (1MB/s, appr 0.8x) is fine if
burnproof/whatever is turned on in the drive, it's just slower. DVD+RW
doesn't even need anything special, it'll just be slower. Likewise if DMA is
off and the system can't supply data at the required speed (indication of
this is 100% CPU load). Kernel-time being stuffed doesn't cause faulty disks
by itself.

Recently I had the case of a box just crawling, couldn't find out why, CPU
load displayed as close to 0. Kernel-time was fine, DMA on, but burning
DVD+RW still only proceeded at 0.6x. No doubt it would have worked, but a
reboot was faster.

Re: DVD+/-R writers

2003-11-20 Thread Volker Kuhlmann
 If you continue to repeat the marketing lies from the DVD+ alliance, nobody
 would believe you.

Perhaps the DVD+- are telling lies about each other, wouldn't be surprising.

 If you believe that DVD+ is able to do things DVD- can't so please name these
 features.

Going by my own observation and not what someone tells me, it seems random
access write to DVD+RW is rather easier than to DVD-RW. I don't have to
blank the disk, and it still works at 0.1x speed. Andy's DVD+RW kernel patch
isn't meant for DVD-RW - could this be because DVD-RW doesn't allow
something?

+/- compatibility issues are just a question of time, one would assume
dvdrom anything which can only read - are no longer being made. cdroms were
in a similar position once.

rigour - i.e. run Ogle, watch how jerky it is, check CPU load. Turn DMA on, run 
Ogle - smoooth motion, lower CPU load...)

However, in my attempts to get the writing to work, I tested with DMA on and 
off, with broadly similar results. Indeed, (subjectively) writing seems *less* 
flaky with the DMA *off*. Which seems so wrong to me.

Also, most of the disks I have managed to burn with dvd+rw-tools have been with 
the DMA *off*. Well, I'm pretty sure it's off - not at that machine just now...


 
 While I have one + drive, I haven't tried + media in it, I find no 
 advantage in price or speed, and a backup is a backup, the DVD-R read 
 okay on more DVD-ROM drives I have, so that was the end of my 
 interest.

Well, I had the DVD+RW media anyway, and no -RW disks, so it made sense to test 
it.
Indeed, the Mac managed to read the +RW disks fine, and it has a DVD-drive in 
it (a Pioneer) so I guess that's all the compatability testing I need for this 
job!

 The write speed is interesting,  although what it means on a 
 fail is not obvious.

Yup. Asked for 1 - reported 4. But I think on a fail it probably isn't true?
Still, the drive and the media are both spec'd to support 4x writing, so that 
in itself shouldn't be an issue I guess, anyway.

Re: DVD+/-R writers

 If you like to buy a single format writer, buy DVD-, it is standard has less 
 readibility problems

As you keep on propagating this nonsense (one might also call it FUD),
for the record: DVD+ isn't any less standard than DVD-. Anyone can call
themselves the standard. Despite the FUD the DVD- people are putting
out about DVD+, DVD+ isn't going to go away because it has a few things
to offer DVD- couldn't possibly dream of (hence the need to resort to
dirty tricks). As I can make out DVD+ is gaining momentum, and
personally I wouldn't dream of buying a single-format burner - I
imagine most people might think the same and the days of single-format
burners are numbered. Any decent player has no problems with either
DVD- or DVD+ as long as the media quality isn't rock-bottom.

If you continue to repeat the marketing lies from the DVD+ alliance, nobody
would believe you.

If you believe that DVD+ is able to do things DVD- can't so please name these
features.

It is rather the other way round. DVD+R and DVD+RW are two disjunct formats
and both offer only one write method. DVD-R and DVD-RW build a group and
support several write methods - including what DVD+ offers.

 There is a firware update to 1.03 for the Plextor 708A. I applied it on mine
 and it's Ok so far.
 -Dyson

I know of this, but according to what I read about it it did not
add too many new media. I would update if I did not have to
use DOS/Win for this. How did you do it? If you used a Linux
tool, I would be very interested in the details..

I just asked Plextor for the neexed info. Lets see what happens...

Re: Write problems with unbranded DVD[+-]RW drive...

2003-11-20 Thread Joerg Schilling
From: MacArthur, Ian  (UK) [EMAIL PROTECTED]

At the weekend I got an unbranded DVD writer - I was in a local electronics 
shop, it was on offer very cheap. I have *a lot* of data to archive, and it 
seems like a bargain...
Claims to support + and - RW writing. 
(The retail box is marked PIKA ONE, but the drive itself is unbranded.)

Installed the latest cdrtools from source. It's what I know, so it seemed 
sensible to stick with it, it's always worked well before...
Installed in place of my CD burner, burned some test CD's with cdrecord, all 
worked fine.
Installed Ogle and checked I could watch DVD's smoothly - worked fine.
Installed cdrecord-ProDVD test binary.

A test run -dummy went smoothly, but the actual burn failed (see sample 
failure below).
This is with Verbatim 4x DVD-R media, in case that matters.
Fiddled about with hdparm in case my DMA settings were a problem, no better.

Tests with dvdrecord fail in exactly the same fashion (and again the dummy run 
is good.)

(coaster count now at 4 and rising...)

However, tests with dvd+rw-tools (my 3rd scheme...!) have all worked 
perfectly, both with DVD-R and DVD+RW media, so I guess that basic drive is OK.
At least, I can read the disks it's written back on my Mac, so I guess that's 
OK!

Is it likely something in my setup that's upsetting the cdrecord derived 
tools? 
How do I pin this down and fix it?

Base system is linux, with a 2.4.16 kernel, latest cdrtools tarball... what 
else do we need to know?

TIA for input.

 I just asked Plextor for the neexed info. Lets see what happens...

Pleased to hear that :)

I just sent a mail (see below) to [EMAIL PROTECTED]
Maybe some more people reading this list can send similar requests?
Not all of you have a Plextor, but you can duplicate and send to
other manufacturers too. Perhaps also to info@ addresses as potential
customers (that did not already buy, but would if Linux is supported..)
OK, that probably wont change much, but at least we have to try :)

--- support request

Hello Plextor,

I purchased your DVD recorder model 708. I want to run it
with Linux. You link to some resources on your website
at page http://www.plextor.be/English/technical/linux.html

CDrecord does not at all work with the 708. I know this is
not primarily your responsibility, but I want to express my
request that you do everything to support the author.

There is another project named dvd+rw-tools, that currently
works in many cases with the drive:
http://fy.chalmers.se/~appro/linux/DVD+RW/
Perhaps you can add it to the Linux-page?

Another chapter is firmware updates. The author of cdrecord
also maintains a Linux flash utility, but it also does not
know the 708 yet. Again, please supply the author with all
necessary information or hardware as soon as possible.
The firmware itself is packed into an .exe - why dont you
use a standard format like zip? At least alternatively.

I am sure there are more users interested in recording on
Linux - please reconsider to increase your commitment
regarding Linux. If Plextor becomes the brand of choice
for Linux users, this is a target group that may be more
valuable than its pure number suggests. Maybe Plextor already
is better for Linux than many other brands - but it sure is
far from real good..
One thing is sure: the Linux community is growing. Multimedia
with Linux is gaining ground (mplayer, VDR). Lots of people
build their own HD+DVD-videorecorders on this basis.

Thanks for reading.
Your hopeful customer..
