Hello...
I have a g4 tower, dual processor, plenty of RAM, OS 10.2.8, superdrive Pioneer DVD-RW DVR-105...
I have been having problems lately burning data onto CDRs. When I use Roxio toast (5.2) I get this error message:
sense key=illegal request
sense code=0x72 ox03
session fixation error incomplete track in session
when I try to burn through the Finder, everything appears to be going fine, it gets all the way through verification but then says something like:
"You have inserted a disc with no volumes Mac can recognize"
the odd thing is that I have been able to burn audio CDs with Roxio. And have been able to burn DVDs with IDVD. Are the superdrives not designed for CDRs? Only for DVD-Rs?
Anybody have thoughts? Very much appreciated. Thank you!
Rob

Rob,
You should have no problems making data CD's on any disk burner equipped mac!
The burn process is slightly different for audio CD's vs data CD's (and of course DVD). I have a suspicion that the cause of your problems are the CD-r's themselves rather than the Mac or burner. Some CD-R's work better than others (same for DVD-r). I suggest you try a different brand of CD-R and see if it makes a difference.
Avoid like the plague, those un-branded super-deal packs you get in supermarkets etc - you know the type: 100 disks for £10. Always go for well known makes (eg Verbatim, TDK, Maxell etc) and select the burn speed appropriate to your drive. You don't mention exactly what computer you have but its likely your burner can only run up to 8x for CD-r (!) so going for the slower CD-r's could be best. Its NOT the case that faster disks are better than slow burn disks. You may also find that burning your data disk at a slower speed helps.
See if another brand works better - it might be worth buying a few different brands for experimentation.
Let me know how you get on.
regards
Tom

Thanks Tom,
But I doubt that's the problem. I have tried different burn speeds and different brands, and still get the "..no volumes Mas OS X can read..." error, at the end of the verification.
The other curious thing is that burning data DVD-Rs through the Finder is not a problem.
Thanks again, I'll just have to keep trying and see what I can figure out...

Rob,
I shall put your query back in the pool. It could be another tech has seen this before and provide you with a fix;-)

Hi Rob,
This is actually a somewhat widespread problem, and yet as far as I know nobody's found any sure-fire solutions. It seems that a lot of different problems have all the same symptoms, so it's hard to diagnose.
One possible solution I've heard is to clean your SuperDrive's laser lens. This can be done with special lens-cleaning audio CDs, which you should be able to buy for $5-$10 at any computer or video game store. Be careful which kind you buy, though, because apparently some only work in CD drives, not DVD drives. This solution has been reported to work in cases most similar to yours, with the Finder properly burning DVD-Rs.
Some people also say the problem just went away after rebooting. I don't know if you've done that already, but "reboot" doesn't even seem to be in the vocabulary of many OS X users these days.
I've had some luck in the past using FireStarter (
http://www.macupdate.com/info.php/id/11417) to burn discs in cases when Toast and the Finder failed me. It's not exactly a solution (I mean, Toast and the Finder ought to work one way or another...) but still, it's worth a shot.
As a general troubleshooting test, you may want to try creating a new user account. If that works, you'll know it's a software problem limited to your regular account.
If possible, it would also help to boot from a different installation of OS X and test it with that, but I realize that might just not be possible. If you have a spare HD around, though, and nothing else works, I definitely recommend doing a clean install of OS X on it for testing purposes. This could be a hardware problem, and the only real way to verify whether that's the case is to test it with a clean system installation.
Also, out of curiosity, did you run Disk Warrior shortly before this problem appeared? Some other people with similar problems say it started right after using DW, although I haven't found any reason WHY, exactly. Also, have you altered the region settings of your drive or changed the firmware in any other way?
Hope this helps,
-Matthew

Matthew,
Thanks very much for the ideas. I'll give them a try and see what happens.
I haven't run disc warrior...
I find it odd that a cleaner would help...isn't it the same laser that is writing the DVD-Rs that work and the audio CDRs that work?
Do you think there is anyway that a problem with my Toast software is causing a problemn with the finder? I should probably re-install.
Thanks again,
R

All modern CD/DVD drives actually use many different kinds of lasers, for the many different kinds of media they can read/write. It takes different lasers to read DVDs, read CDs, write CD-Rs, write CD-RWs, etc, etc. Many older DVD players can't even read CD-Rs, actually (yet they can usually read CD-RWs!).
So it's conceivable that some dirt on the lens could interfere with one of these tasks without affecting the others. (It does seem strange that you can write to CD-Rs properly when burning them as audio CDs, though. Yours is the first case I've seen with that twist.)
As far as I know, Toast wouldn't interfere with the Finder's burning, but I guess it's possible. I'm pretty sure it wouldn't interfere with Firestarter FX (which I mentioned in my last reply), though, since that's a Unix-y tool that actually makes you choose which driver you want to use (don't worry, the default is good for most drives).
A clean install would be great for testing purposes, but it's a last resort in my book. Reinstalling Toast (and updating, if necessary) is probably a good idea, though.
Cheers,
-Matthew
