Firmware upgrade for Matshita DVD-R UJ-845E to burn dual layer DVD?

Dear All

I have a PowerBookG4 with a Matshita DVD-R UJ-845E which it seems apple has disabled from burning dual layer DVD. I've read around that there are firware upgrades that can enable actions again. I can't find any for Matshita DVD-R UJ-845E, though. Any ideas?

Thank you!

I'm not sure if this is true what you became told... in order to burn a dual-layer DVD you need a laser beam that is able to refocus - that requires a special optical hardware. See http://www.pcmag.com/article2/0,1895,1631717,00.asp for technical details.

So unless they simply have disabled this feature (why should they do ?) by software, it may work to bring it back to life.

But I'm sure to 99 % that there is no such "software-upgrade". Anyway, surprise me 😉

hi Tobias,

thanks for your reply though not very optimistic, is it?

Well all the info I have about the Matshita technically be able to do the job comes from here:
http://forums.macrumors.com/archive/index.php/t-160207.html

Also in an older discussion I found this:
http://discussions.apple.com/thread.jspa?messageID=1645648&#1645648 (look fot a post from Donald Morgan), but still no answer.

So, still waiting I'm afraid. If there is no way to do it I won't bother, but if there is I would like to try it.

Not really. It is a fact that you can't convert a single layer drive into a double layer drive, this would be like trying to turn a DVD player into a DVD recorder, just by telling the firmware that it is able to burn DVDs. This is a hardware thing, not software controlled.

The macrumors.com forum you mention speaks of a UJ-846, which is a double layer drive used in later PowerBooks. Also I don't would take it too serious what this forum states.

Donald Morgan has a high score, so what he states may be serious. Have you tried to contact him asking about ? I just see that he has hidden his e-mail address, but you may open another thread addressing him directly.

You can leave this question unanswered for some time, too. Maybe another one tells you if there is a firmware update.

If you want to go really sure, why not visiting (or calling) an Apple Store or phone the UK Apple store. I don't see a reason why Apple shouldn't tell the truth...

The only alternative would be - if there is no firmware update - to get a replacement drive and installing it. Or, easier, use an external USB or firewire one.

angie1976 you have me directly.
As stated in previous posts there have been several issues with the Matshita Optical drives that Apple has installed in there computers. Over time the problem has been discussed and it would appear that there are several things that come into play here.
Apple has made it so that many of the drives they intall are in fact not capable of there full potential.
It in fact boils down to an issue of Copywrite Infringment. Apple doesn't want to put itself in a position to be open to Lawsuits from the Motion Picture Industry.
Many of the drives that do not work up to there full potential have FIRMWARE updates that are offered by the manufacture to remedy this problem and some do not.
It has also been found that the casual user that burns DVD's isn't aware of the huige difference in the Format's available for DVD Burning. and the many limitations of these different drives as far as Media and Speed of Media is concerned. Many of the DL burners that were installed will not burn DL. Apple has had such a huge amount of dissatisfied customers that many that will take the time and if they still have AppleCare these drives will be replaced free of charge.
Here are a collection of links that will help you to understand the problem as it exists.
I will also say that upwards of 85% of the problems user expieriance is with POOR QUALITY MEDIA.
http://www.digitalfaq.com/media/dvdmedia.htm
http://www.videohelp.com/dvd
I also noticed that some others have chimed in as to the fact that Media was not the issue. This is not entirely true.
Here is another post that I answered that will also cover this subject that may help you understand the problem a little better.
Let me see if I can shed some light on this issue, for you.
Maybe some others as well can.
There are several Applications that are standard programs that come with OSX.
Of these, several have the ability to burn a project.
iTunes....iMovie.....Disk Utility.
Each of the above mentioned applications were developed for a specific purpose. However, they are capable of doing more than the original developers intended.
The problem in my eyes is the lack of information for a new user to Mac.
In what one would consider the perfect world, you simply choose a project, drag it in to one or more of the applications mentioned above and simply click burn and you are finished.
This is not always the case.
Often users are left with the issue of no clear cut direction on how to use these different burning softwares, and the ability to have a clear cut step by step user interface.
All of the furnished OSX burning software is in fact usable and works well.
The problem is HOW TO USE THEM.
The more experienced users find this either to be a non issue or will take the time to work with these different applications until they figure out how to use them.
There are of course different Advertisements and FAQ's that cover these to some degree that leave users more confused than when they started.
One of the major issues that accompany this problem is this.
Not all Burners that Apple uses in there machines are the same.
Not all Burners will accept all the different Media's that are available on the market.
Thus leaving many users confused. Not having a clear cut understanding of what the difference is between these different Media's and there use.
http://www.videohelp.com/dvd.htm
The above link offers an overview of this subject.
Apple has found itself in a delima with the Motion Picture Industry, as well as The Music Industry over the issue of offering there users with the capability of copying Copyrighted material. Thus leaving them open for Law Suits.
There was an in-depth article in one of the recent issues of Macworld Magazine, that went in-depth covering this issue.
It is almost impossible to cover all aspects of this issue on these forums.
There are of course different softwares available that make the burning experience much easier and user friendly.
Roxio is one of the industry leaders in the development of Mac compatible Burning Software. They offer 2 of the industry leaders in this area.
Toast-7 and Popcorn.
This solves only one portion of the problem. Both of these software offering give the user the ability to copy about anything.
However, there is so much controversy over the issue of Movie and Music copying, the manufactures of the Computers, and the Burners try to limit the users ability to copy these, and thus be clear of any Legal Issue.
Here again rises the problem of computer users being mad because the industry has placed limitations on there ability to use there product in a fast easy to use method.
Again there are work around to all of these issues.
The problem then becomes who out there is willing to tell us what is the easiest most trouble free method of using these computers, burners, software,and media.
The burner manufactures offer there burners.
To get them to work to there full potential the users then must search out the 3rd party Firmware updates that will enable them to work properly. This is not an issue with all burners but quite a few.
Most readers on these forums have read about the MEDIA compatibility and poor quality issues these are covered in a prior link.
To sum this up, the resources are available to do just about anything one wants to do in the copy area.
Not every copy problem is the same because of all the different elements that come into the equation, Burner, Media, Software, Firmware.
So if a user has a problem and needs the information and the resources to copy there projects whatever they may be.
Be through, give as much information as you can.
Keep it simple, No need for the use of exotic terms that most people don't understand anyway.
In-depth. Tell all aspects of the issue and what you have what you are using and what you want to accomplish.
If there is an answer out there.
Someone will Chime in.
The users on these forums for the most part are more than willing to share in there knowledge, free of charge.
One last thing,
When a user gives you an answer for you problem, for the most part they believe it to be a fact. Sometimes this isn't the case, we have all been guilty of, this is not done with malicious intent. It is done trying to help.
I personally have been misinformed, or tried a fix, that will work in one instance but not another. So tell all you can about your problem.
Cheers Don

But now let's go into detail for this specific drive: DVD-R UJ-845E. I think angie1976's question was whether or not this drive is capable of burning dual layer DVDs (not sure what her system profiler states, maybe just looking there shows the media types that are burnable - at least without firmware update).

Just a final note: Updating the drive with a firmware that is not authorized by Apple (or the drive manufacturer) leads to losing any warranty.

Jan 17, 2007 2:17 AM in response to Donald Morgan

Just asked for interest: When have you bought your PB with this drive ? I just wonder because my DVD drive is labelled UJ-825, which seems to be older (although I own an Aluminium-type PB G4 17").

I can just remember to PBs with/without double-layer drives offered (only the last series of them had DL-drives, if I'm not totally wrong). Mine is not capable (according system profiler) and yours obviously not, too. So I ask me if there is a reason why Apple decided to use different drives ?

Jan 17, 2007 3:39 AM in response to Donald Morgan

Oh dear,

thank you very much. I'm flooded with information. I found out that the Datawrite Titanium DVD+R DL I got might not be the best, so I will get some better ones and try again. What actually happens is that I put the disc in the slot and it makes grinding noises, it doesn't come up on the desk top, and at the end it ges ejected. Nothing else, no errors, no nothing. So much for a problem discription. Burning DVD-Rs (Fujitsu) has been perfect so far.

Can I ask something else? Can physically theMatshita DVD-R UJ-845E burn DL DVDs? If it can, but apple has disabled it (infrigment laws etc), is there or is there not a firmware upgrade for the Matshita DVD-R UJ-845E. And where can I find it?

Cheers Don!

Jan 17, 2007 3:58 AM in response to tobias Eichner

yeap,

I have an aluminium PB as well, I got it around July 2005a and with the drive in. The specifics are:

MATSHITA DVD-R UJ-845E:

Firmware Revision: DMP2
Interconnect: ATAPI
Burn Support: Yes (Apple Shipped/Supported)
Cache: 2048 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW
Burn Underrun Protection CD: Yes
Burn Underrun Protection DVD: Yes
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
Media: No

So it looks like it doesn't do DL.

Jan 17, 2007 6:59 AM in response to angie1976

Your system profiler states:

CD-Write: -R, -RW
DVD-Write: -R, -RW, +R, +RW


Therefore you can't burn DL media, this would be stated there.

So "the" question is right now: Is there a firmware update available that can teach your drive to burn DL media ?

Before you don't have an answer (mine is above, a 90%-"no"), I would not spend money for buying DL media. You will not be able to burn them at this stage.

Jan 17, 2007 7:43 AM in response to angie1976

Your Matshita UJ 845 E by what you posted from your profiler does not support DL.
As Tobias has stated that many of the fiemware updates are in fact 3rd party or open source and do in fact void waurntee's that being said there have been so many different drives used by apple it can be a pain to keep up with them all. You can usually get the latest on firmware and different options by checking with Google on your paricular drive. You will find out just about any options that are available. Remember that many of the computers mid year or 1/2 way through a year might change a particular drive 2 to 3 times and some times use as many as 3 different suppliers as well.

Jan 23, 2007 5:19 AM in response to angie1976

If you can find a firmware update and are successful in flashing the drive with the new firmware then you can burn DL.

The easiest way - if DL capability is that important - is to get a new OEM drive that is has not been flashed with Apple Cripple-ware and replace your internal drive. An external drive might suit your needs over the hassle of changing the drive in your computer. You can get an ext drive with DL capability for $150 or less.
