Tecra 9100 won't read burned CDs

Hi.
I have a Tecra T9100 and the MAT****A DVDROM now won't*read burned CDs.
It has no problems when reading manufactured CDs / DVDs.
I noticed this after upgrading the BIOS with the 1.6 version.
Is there something else I need to do / configure / install ?
Thank you.

Hi
Maybe you should check different CDs from different manufacturers and should change the burning speed to the slowest one.
If this will not help then a CD/DVD drive issue might be the reason why not all disks are readable.
Cheers

My 24" iMac won't read audio cds--ejects them after about 15 seconds

My 24" intel iMac won't read audio cds. It ejects them after about 15 seconds. I have virtually never played cds on this machine in five years. It plays dads with no problem. Anybody have any feedback. I also saw a fix by deleting some presence files.

I saw this on a forum from about four years ago:
Trash the following folders:
com.apple.kernelcaches (from System/Library/Caches
extensions.kextcache (from System/Library
CDInfo.cidb (from Home/Library/Preferences
Restart
Could this be a fix.
Unfortunately, I can't reset PRAM. I've done it a thousand times over twenty years,but my machine simply boots up without the extra chimes.

Imac 10, 1 won't read certain CDs

my imac , iMac10,1; Intel Core 2 Duo won't read certain bought CDS and spits them out. We can hear a whirring noise-- but not the clicking sound of the tracks being read-- and then, the CD comes out.
all software updates have been performed.
please help and thank you.

iMac Superdrives are notoriously finicky - what brand are the ones that didn't work? It could also be that the media is slightly scratched, dirty, or the printed side is not in perfect condition. My iMac (only) likes Verbatim.

Problems reading/burning cds

dvds and program cds are working, but itunes is not reading certain burned cds, and i am having trouble burning cds.
today i tried to burn a playlist, 17 songs, 1.1 hrs, 72.7 mb on a 80min/700mb cd. it failed almost immediately and gave the message, "the attempt to burn a disk failed. the device failed to calibrate the lazer power level for this media."
a previous attempt to burn a cd gave me a message saying something about an unused underwrite buffer or something, i should have written that message down too. any ideas?

Welcome to Apple Discussions
You possibly are using CD's incompatible with your CD writer. What speed are the CD's? I use Maxell 48x with my iMac with no problems, however, I find my iBook likes the 32x. Different writers. The iMac is a SuperDrive, while the iBook is the standard CD/DVD.

10.5.7 Won't Read Audio CDs?

I installed 10.5.7 a couple of days ago. All went well and continues to do so except for 1 minor quirk, none of my audio CDs can be read by the dvd drive, I have managed to burn both CD and DVDs though using toast 8, but I'm unable to read audio CDs new AND old. Anyone one else having trouble with Audio CDs? [DVDs are fine]
Macbook 10.5.7, 4 gig ram 160gig hd

First, my MBP plays CDs fine, so it's not 10.5.7, at least in my case.
What happens when you insert an audio CD? Does it appear at all on the desktop?
Try a PRAM reset.
AFAIK, the lasers for reading CDs and DVDs are different. CDs use a 700nm laser, DVDs a 640nm.
The lasers for burning are different again.
It's just possible that the CD laser in your drive is not working.
Other than a PRAM reset, I am not sure what you can do.

Won't read selected CDs & CD-Rs

hey guys!
why is it that my iBook won't read/load selected CDs and CD-Rs which my PC can? how can i fix this problem? thanks.

I believe there are detailed instructions in the Nero user guide. Download it here http://www.nero.com/en/UserGuide_Burning_ROM6.html
and search it for "Mac".
Of course, if this doesn't help, please post back! But I hope it helps.

Not reading burned cds

my imac won't read anything burned by another computer, mac or not. is there a driver i could download for this, and if so - which one? i have no idea when i get to driver downloads where to go. thanks in advance for any help! have a great day!

Samantha, Welcome to the discussion area!
There is nothing to download to add this ability. Your iMac should be able to read those discs.
Have you tried cleaning the optical drive? Use one of the kits that contains a CD with brushes on the bottom. This will clean the dust off the laser lens.

DVD burner won't read burned DVD's

We have a dual 2Ghz G5 with 2.5Gb's of ram that used to be able to read DVD's that had been burned. Now it will read only commercial DVD's and CD's (it can burn CD's fine). It won't accept non-burned DVD-R's either.

Hi.
I have almost the same problem:
I bought an PM G5 2x2Ghz with 1Ghz of RAM in november 2003, and my superdrive is a model PIONEER DVD-RW DVR-106D that used to brun any kind of dvd's an cd's and had no problem to read burn dvd's.
But now, it can only burn DVD-R (but no problem for the CD's) and most of the old Dvd's that i burned on my G5 can't be read anymore.
Can someone tell me what's the problem and how can it be solved.
thank you very much.
bye.
PS: Is it normal thaht i've never been able to read a DVD's burned from windows on MAC OSX but CD's yes?

CD/DVD drive won't read any CDs or DVDs

Whenever I insert a DVD, CD, or CD-ROM my computer won't read the disc. The computer starts making noise like it is reading the disc but then it stops. It tries 3 times (starts and stops) and then just spits the disc out. I can't watch movies, install software, etc. How do I fix this.

Before taking it or sending it anywhere I'd first try resetting PRAM…

Mac computer won't read burned discs, need help...

Heya,
So I'm not sure when this started happening exactly, but my Mac stopped being able to read burned discs for some reason. I've tried discs that have audio (legal MP3's) and applications on them (also legal copies of the discs) and they show up in finder but as a blank disc. I'm wondering if there was an update of some sort recently that started causing this issue somehow? Can someone help? Thanks!

Related Problem?
I have had my MacPro for more than a year, just updated to OSX 10.6.4
I have not been able to play a particular,commercially bought DVD. No clue about the format of it. It comes up as Untitled. My MacPro has worked OK with other video DVDs and a bunch of install discs. I just discovered this new DVD player problem today, with this new DVD just bought through snail mail.
However, this same new commercially recorded DVD plays beautifully on my old 17" powerbook bought brand-new in 2006, today running OSX 10.4.11
It is sad so many bloat features seem to cloud real needs of working people, or what else could it be? My system has had some other livable problems like the fact i had to trash the much needed OSX Dictionary Application, because it started opening up a window for every word i already looked up-- This problem seems to be due to Migrtation Assitant picking up some weird police state aps or what not. It is hard to live without Migration Assistant because aps like CS4 are so hard to get running on a new system. So grin and bear it.

Itunes won't read burned cd-r but applications like vlc does

Well as the title says I'm having some issues with Itunes not being able to read burned cd's of any brand. The cd's are burned as a red-book in waveburner and works on standard cd-players and for some reason when played through VLC.
But when I use the preview in finder and itunes all tracks are skipped.
This started to appear after a complete re-install of OSX and i have tried to re-install Itunes as described in the support.
Happy for any input that might ease my frustration
Best regards Jimmy

Hey, thanks for your reply. I ran Diagnostics and the results are as follows:
Retracts: 38
Reallocs: 56
Pending Sectors: 8
PowerOn Hours: 165
Start/Stops: 12666
Temp: Current 29C
Temp: Min 15C
Temp: Max 52C
I heard that a large number of Reallocs is bad; not sure if 56 qualifies as a large number. Would this somehow interfere with iTunes not being able to read the iPod?
EDIT: Your instructions say to attempt another Diagnostics after updating however my iPod will not update past 2.0.1 (I believe that is the last update that came out for iPod Classics), unless you'd like me to recover/restore it and then try again.

Vaio SVE15115FXS Won't read dvd/cds

Recently my Viao (model referenced in title) stopped reading dvds/cds. The tray ejects and the disc spins for a few seconds and then nothing. The drive is not listed in Explorer. I uninstalled the drive and restarted the PC but did not fix the problem. I've been searching for hours on how to repair this. Any advice you guys can provide is greatly appreciated. Thanks

Combo won't read burned DVD

Hi, i know this is not new but since i can't find any solution and apple support prefer staying behind the scene, i posted my problem.
I have a DVD with all my works files which is burned at the office using PC. Once i was home, i tried to copy the files to my emac (1,25 GH, 512, Tiger 10.4.2). It works for a while and then it stopped and saying can't find xxxxx file which is actually in the dvd. So i tried a couple times and did not work. I rejected the dvd for the first time it won't come out and i restarted the emac so it came out. After i restarted the emac, the combo drive won't take any burned DVD anymore ( i have memorex DVD) but it can take any comercial DVD or CD, e.g i insterted the Tiger upgrade DVD and it works good or Adobe CS CDs it works good. I was cleaning the lens using Memorex lens cleaner, it still throws my burned DVD out after a few second.
So what should i do? is it software or hardware problem? hey apple guys where are you !

The Apple Discussions are peer-to-peer exchanges among Apple users; if you want to contact Apple Support, try the "Contact Us" link at the bottom of the Discussions pages.
If you look over other posts in this forum, you'll notice a common current complaint involves using 8x DVD media; can you try using 4x media?
Also, there are differences between DVD-R and DVD+R media; for Ma cuse you'll generally want to use DVD-R.
As a general tip when burning CD-R or DVD-R on PCs to be read on other computers, burn the PC disc as a read-only (closed) disk. Leaving the disc appendable or multi-seeion capable can make it unreadable on other computers, even other PCs that don't have the exact version of the same burning software you used to create the disc. Finalizing or closing or making the dic read-only --- whatever the burner program calls that option, it tends to work better.

DVD RW DW-U10A won't read burned Dual Layer DVD

My friend created a dual layer dvd for me on his PC. I put it in my G5 and after about 15 seconds of the drive trying to read the dist it just gets spit out. It won't mount or anything.
Why is this happening? I've never had problems reading discs created on a PC. Is my drive incompatible with DVD DL+R media?

Hi,
I've been having a similar issues since not long ago. I think it coincides with Apple,s last security update (although I can't swear the 2 are connected).
I have a dual core 2GHz PowerMac G5 with a Pioneer DVD-R 110D Dual Layer.
I'm burning Dual Layers medias with Toast 7 (DATA, DVD-VIDEOS ETC). They all mount fine after and I can read the files etc. However if I insert the discs a few day slater, about 50% of them won't mount and are rejected without any error message!
Anyone else has this problem?
