How to make Combo drive read DL DVDs?

As you see the question in Subject.
Thanks in advance,
Ivan

The combo drive in my first eMac (700 MHz) couldn't read DL DVDs either. It could read the first layer but skipped and got hung up when it got to the 2nd layer. A trip to an Apple Store and a call to tech support revealed that the drive in question was never intended to support DL, and well, too bad.
The point is, if your friend's drive is old enough, it simply may not support DL, and no amount of software finagling will make that capability appear in the hardware. Your only options are replacing the drive or adding one via FireWire, (or USB2 if the machine supports it).

Can Combo Drive read dvd double layer?

Can Mac Mini Combo Drive read dvd double layer?
Thanks

It should be able to handle commercially-made movie double-layer DVDs.

What DVDs can combo drive read?

Can my Powerbook G4 12 inch combo drive read DVD+r? DVD+r dual layer? DVD-r dual layer?
I've found conflicting information online. Thanks.

This subject matter can get quite confusing. Companies have confused the "Dual Layer" term and crossed their wires doing so. I have posted detailed info in this thread:
http://discussions.apple.com/message.jspa?messageID=5095860
Also, if you have the 12-inch model that I do, the 1.5GHz SuperDrive edition, then it reads both DVD-R and DVD+R discs. (A DVD±R drive). It will read DVDs with two sides to it, a side A and side B disc, you know, the ones with no artwork on the disc that look like bootleg DVDs but aren't?
It won't read discs that have two writable layers in it.

Welcome to Apple Discussions, humain.
I have been burning DL DVDs from another Mac for quite some time now. Never had any problems with the DVDs being unreadable on my PowerBooks except when there was a bad batch of discs, which then meant only the Mac that burned the disc could read it.

Combo Drive read DVD but refuse to read CD

I have the problem that I can use the combo drive only with dvd when I try to insert a cd it will not recognise and the drive eject the cd. I have checked al kinds of cd´s and I have also tried to burn a cd but without sucess. I have also reseted the PRAM but also without sucess.
Is there´s a chance not to buy a new drive ?
The Ibook G4 800 Mhz is just 2 years old and handled with care so I can not see any fault which causes the problem.

The drive was damaged I have bought a new one. bad luck just 2 years old and not used very often. Since 8 Month I have an IMac G5 and since now I have the same problem with a superdrive but good luck because I still have warranty from Apple. It seems that the slotin drives are not the robust ones.
Does other users have the same expirience ?

Combo Drive rejecting some DVDs

My system: Mac Mini Core 2 Duo with Combo Drive.
Some DVDs have been working fine. I have checked around 10 or so earlier today which worked fine, although in a few cases I did hear particularly loud sounds coming from the drive, which I'm not used to hearing from an otherwise relatively quiet drive.
But I've just encountered a disk which the Mac ejects immediately. That isn't always the case -- sometimes it doesn't eject it, and it shows up as a blank recordable CD (yes, a CD. Go figure.) Just now I tried the same disk again, and this time it shows up in Finder as a DVD but DVD Player still refuses to play it. Which of these behaviours I get seems to be purely chance, more often than not it just gets ejected straight away.
I initially thought it might be a bad disk but on testing all subsequent disks from the same series, the same occurs. Interestingly the first of the four has no problems, and plays through as expected.
I have tested the same disks against my MacBook Pro, and verified that they not only play, but that there is no issue accessing any of the data on the disk -- I can copy the contents to a folder with no problems at all. Move the disk back to the Mini and bam, rejected again.
Just now (to gather more information, check more stuff) I put the first disk back in again and that worked as expected again. And now the second disk is recognised as what it is by Finder, although the DVD Player still claims it's an unsupported disk (go figure...)
Anyway I wanted to know if this behaviour had been seen by any other Combo Drive owners in the past, whether this commonly happens with certain DVDs, or whether it's a problem with the particular drive in my unit in which case I will get it fixed.
Or maybe the disks are faulty in some way which the MacBook Pro is more tolerant with? :-/

(phone only... what is this, 1995?)
If you are within reach of an Apple store, call there and make an appointment at the genius bar. Free support for all, whether in or out of warranty.
whether it's possible to upgrade to a SuperDrive
If your system doesn't have one, it's certainly possible to replace the internal with a superdrive, but to be honest I would not advise it. Having Apple do this would be expensive, though there are bare drives for the user to upgrade themselves at OWC (http://eshop.macsales.com/shop/mac-mini/superdrive/) amongst other places. However, these slot-loading burners are rather more fussy than external devices have tended to be, so it may be a better bet to simply add a Firewire external (http://eshop.macsales.com/item/Other%20World%20Computing/VLFWU2D112/ for example)
Given your system is new, however, I'd have Apple check out the combo drive first anyway, but add an external DVD burner if in any doubt.

How to make a driver using DLL in LabVIEW?

I had followed the "Using Exteranal Code in LabVIEW" manual having finished the making dll file, and the lsb file(I attempted that two ways). But when I load the code in LabVIEW, it can't work. I don't know what had happened, I only got a error message like this:"'0x100014f1'commond call memory'0x00000000',this memory can't be written" or other similar error message, if I push the "enter" button, the vi application which I having lunched will crash. If I push the "cancel" button, the debug model will start,and the next message is "Unhandle exception in LabVIEW.exe(MSVCRTD.DLL/LVS95.TMP/COUNTER.DLL(the last one is creat by myself)):0xC0000005:Access Violation", but I wonder what had cause this? My DLL had been made successf
ully under the VC++6.0, why LabVIEW can't call it fluently? How to make a driver for my own device using LabVIEW? How to correct my error to finished my hole work? Thank you very much. Jacky Wei

1. Can you call this DLL from within VC?
2. What operation system do you use? There may be a problem with calling of win95 dll under NT or win2000 for example.
3. If you use NT you may not have permissions to work with some ports and memory areas.
4. Under NT or win200 try to compile the library as a 32-bit dll, and under win95 - as 16-bit one.
Good luck.

Combo Drive reading Dual Layer / booting from external DVD USB

I am helping a friend with an iMac G5. He has the combo drive which is not able to read the dual layer Leopard DVD. I have looked to see if there is a firmware update for the drive however no luck. I am able to put an external usb DVD and it reads the disk however I was not able to boot from the disk using keyboard commands I tried AppleOption+ShiftDelete, C, and also tried Option but no luck.
I have been reading that booting from usb external drive is a no no on older G5 iMac's unless you are using fire wire. If any one can give me some help with getting the USB drive to boot, or figuring out why the combo drive spits out the DVD every time I would appreciate it. I am also willing to make a bootable usb leopard thumb drive, but I don't want to waste my time if it's not going to boot from USB.
Thanks,
jtadmin

Do you happen to have a more recent Mac that can read the Leopard installation DVD?
If so, you may be able to start up your Mac in FireWire Target Disk Mode,
http://support.apple.com/kb/HT1661
and let the iMac G5 use your Mac's optical drive to boot from the Leopard DVD.
Also, it is true that PowerPC Macs can generally only boot from external drives that are FireWire.

Could iBook G4's combo drive read DVD+RW discs?

I want to know whether it can read these ones or not.

Nie Hau!
To answer your question, yes. A combo drive CAN read DVD+RW disks. It cannot write to them, however. You would need a Super Drive for that.

Combo drive reads cds, stopped reading dvds

My combo drive won't read DVD movies. However, it does recognize CD's. I get an error message with DVD discs that reads: "DISC INSERTION The disk you inserted was not readable by this computer."
I took my iBook to the Apple store yesterday and they archived and re-installed my OS. This process made the drive work, but this morning it gave me the same error again.
Suggestions anyone??

"I took my iBook to the Apple store yesterday and they archived and re-installed my OS. This process made the drive work, but this morning it gave me the same error again."
maw87, welcome!
Did you use the same DVDs that worked yesterday when you got the failure this morning? Or are we talking different discs?
Are these commercially manufactured DVDs or home-burnt?

Can my Combo-drive read Dual-Layer DVDs?

I have a Combo drive in a PBG4 12" 1.33GHz with a combo drive. Can I read DL DVDs burned from one of the new Macs? I couldn't find any litterature on this.
Thank you!

Combo Drive Reading nothing but DVDs

I am trying to install a printer on a Macbook, which has a combo drive. When I insert the installation CD the drive doesn't start up and after about one minute it ejects the CD. The same thing happened with a pre-recorded music CD, a blank CD-RW and a blank DVD+R. However, when I inserted a DVD movie it worked properly. On my Macbook with a superdrive everything is working fine.
Any help is very much appreciated.

In case anyone wants to know the outcome.... I reset PRAM and SMC (as suggested by Apple in another user's post), but it did not work. I then phoned Apple and she straight away told me to take it in. She didn't even suggest any measures to try out first, just take it in. This Macbook is 7 weeks old. I was trying to use a printer installation disc and came across the problem. My daughter is leaving for university tomorrow and obviously needs to take her computer. Perfect timing. I am not impressed.

DVD/CD drive read/writes DVD, reads CD, but suddenly fails to recognize CDr

I'm having a problem that I just don't understand, and I can't seem to find any information on, so I'm hoping somebody out there has some thoughts.
I have a powerbook 17 with the DVD/CD listed below (from system profiler).
This drive has always worked perfectly, but now I find that I can:
- play DVDs
- burn DVDs
- play/read CD
but when I insert a CDr to burn, the icon never shows up on the desktop. Running disk utility lists it as a CD (read only) -- I'm not sure if disk utility is valid in this context or not, but I had to start it so that I could get at the CD to eject it.
At first I thought it might be the media I was using, but I tried two different kinds -- both failed, then I found some blanks of the brand and type that I've been using forever...failure.
So, can this be a hardware error? If so, how can a hardware drive error only affect recognizing writeable CDs? If this is the case, I'd like to learn something! =:-)
The only thing that's changed on this system is that I regularly run software updtate...everything's up to date. This is OSX 10.3.9.
Thanks,
keith

Keith, just for grins, go to your Apple and click it and then choose System Preferences, and when it opens choose CD-DVD and see what option you have checked for the different media.
Just a chance when you did an update it might have changed a default setting you had.
