CDs not recognized intermittently

I've had the Macbook for two days and have been burning my cd collection to iTunes, and when I insert a cd, there seems to be about a 1/10 chance that it isn't recognized by the Mac. It doesn't show up in iTunes or Finder. The only solution I've found so far is to reboot. Each time it's happened so far, the disc shows up as normal after the reboot. It "works" but the process is fairly annoying. Drive problem? Software problem? I ran software update for the OS and iTunes, but that didn't resolve the issue.

I have a similar problem on my imac 24 inch with 10.5. I am importing my cd collection into itunes and usually the first time I insert a disc it doesn't show up on the desktop. I have to push the eject button on the keyboard and when i insert the disc again it is recognized.

Burned CDs not recognized on PC

I burned two CDs several weeks ago with one movie each that was recognized and played by my daughter's PC. However, I have burned three other CDs with movies since then in three ways different to the first ones which were not recognized by my daughter's PC and, of course, were not played. I then burned another CD as I had the first two but this CD was not recognized by her PC.
Do you have any suggestions about burning a CD on an iMac that can be recognized by a PC? I don't understand why the first two CDs were recognized and playable and the last one was not.
Thanks for your help.

What was the video format of the movie that was successfully recognized and played on your daughters PC? What program is your daughter using to view the CD?
The movie files were in Quicktime which she has and used to view them.
What program did you use to burn the CD?
I used a burn folder from Finder for the movie CDs.
What is the video format of the other movies that you unsuccessfully burned?
Quicktime.
All CDs played on my iMac with Quicktime and also with RealPlayer.
Any suggestions?

Blank CDs not recognized by burning programs [SOLVED]

EDIT: By some divine intervention, the computer just started recognizing my blank CDs, I have no idea why it just started working, but it did!
Hi all, got a new laptop recently (Dell Vostro 1320) but burning programs don't let me choose a "destination drive", as if one doesn't exist. However, if I insert an acutal DVD, vlc-player will run it just fine. If I insert a blank disk, under gnome's "places" an option for Blank CD shows up, but when I click it, nothing seems to happen. How can I make burning programs recognize the existence of my drive? perhaps its not pointed in the right direction? I have brasero and graveman.
Here is my policy file for HAL
<config version="0.1">
<match user="tom">
<return result="yes"/>
</match>
</config>
I also have my CD/DVD lines commented out in /etc/fstab
#/dev/sr0 /media/cdrom iso9660 ro,user,noauto,unhide 0 0
#/dev/cdrom /media/cd udf ro,user,noauto,unhide 0 0
#/dev/dvd /media/dvd auto ro,user,noauto,unhide 0 0
#/dev/fd0 /media/fl auto user,noauto 0 0
NOTE: I've tried playing around with fstab, commenting, uncommenting, but to no level of success. Please let me know if you need me to post more outputs.
I will try to post some more information about my burning program preferences.
Thanks for your help, and hopefully, it can be resolved!

fstab wont help you at all - that's for reading, not writing.
I know zip about brasero et al, but cdrecord/wodim should be ok to use.
Most probably, your cd will be /dev/sr0 and to burn an iso-image you do something like this:
cdrecord -v driveropts=burnfree dev=/dev/sr0 -dao -eject -data /name/of/iso/image
I hope you realize that cd/dvd-burning is mostly a matter of transferring a whole image, you can't really use it as a 'normal' filesystem (at least as far as writing is concerned).
I guess someone will jump down my throat and tell me it is possible - and it is ... though not in the usual way of using a filesystem ...

OS X 10.5.7 + Battery Not Recognized (intermittent)

After I've installed the OS X 10.5.7 update, I'm having problems with OS X recognizing my battery. The MacBook starts as usual, but suddenly it shows the battery icon with and "X" (as it has no battery installed) and keeps working (note that the power adapter is not connected, so the power came from the battery and it have plenty of charge left). The MacBook do this several times (intermittent) when it runs with battery power.
The battery Cycle Count is 71, and my MacBook is 11 months old (so i have 1 month left before i've to get to expend the Apple Care Plan).
Any answer will be helpful.
Thanks

The symptoms are similar, when I'm using my Macbook only with the battery (remember it's a new one that the Apple Service have gave me) sometimes the battery is not detected and the system goes to sleep (even if a have disabled all the configurations in the energy saving menu).
I've tried to remove the battery and use the Mac connected with the AC adapter and that way it works great.
Today i've reinstalled the 10.5.7. update and I'm still having the same problem but not as often as before but the problem persists.
Next monday I'll be sending my Macbook to the service center and any news that I get I'll tell you.

CDs not recognized [SOLVED]

Hello,
I've been having a strange problem with getting any CDs to be recognized or "mounted" within Arch--they don't show up in pcmanfm's sidebar; DVDs and removable USB/SD work fine, however. What's even weirder is that Mplayer can find and play the CD.
I'm using:
kernel 2.6.31.6-1
hal 0.5.13-3
dbus 1.2.16-1

I've commented out the optical drives as mentioned in several places.
I also had to add "ck-launch-session openbox-session" to my openbox configuration, as I was getting permission errors with accessing removable media before and this seems like the solution. It didn't fix CDs, though.
This is the output of dmesg upon inserting a CD. I'll gladly post any other info as requested:

Certain cds not recognized

Since itunes was updated to 7.01, some of my CDs on my MacBook are spit back out. They won't load.---Those in question are published by independent labels---but they are still recognized by itunes for windows---(an earlier version). The problem seems to be specific to the 7.01 update for Mac OS. Any suggestions?

Certain CDs not recognized won't load ?? Craig Morgan.

I have a Craig Morgan CD that is not even recognized by iTunes.
Since itunes has no actual Open File button I cannot search for the CD either.
Anyone every had this happen.
I think it happened on Natasha Beddingfield too.
This is fresh install of itunes 8, no other music is loaded.
I don't have any other cd's laying around to test, but itunes has always worked
for me.

Certain Music CDs Not Recognized by SONY DVD RW DW-Q28A Superdrive

Subject drive recognizes all DVDs, CD-ROMs, and some (but not all) commercial Compact Discs. Case in point is "Diva," published by Nemo Studios under license to Angel Records. This is an audio collection of Sarah Brightman's performances. Inserting this disc (and probably others) into my PM Dual CPU 2.7 GHz G5 results in "spin-stop-spin-stop-eject." No icon appears; the disc will not mount. I have verified that other CDs mount and their contents will play in iTunes with no problem. The disc in question also mounts, opens, and plays perfectly on my wife's Windows PC.
The firmware of my Sony drive is "KAS7." Is there an available update? Could that be the problem?

"as I wrote above, after it failed to mount, my wife put it in her Fry's PC CD drive and it played perfectly. "
Mac drives are more sensitive than the pc drives. My pc drive plays anything including cracked CD/DVDs.
Again, try a drive cleaner. Another thing you can try is to repair permissions & restart your computer. Sometimes that is all it takes.

CDs not recognized: ANY HELP APPRECIATED

Hello,
I've been an iTunes since the first version and use it on every computer I own. Love it. I am frustrated installing it on some computers at work. I am a music educator and I like to use iTunes to organize and play my library of audio at school.
I have tried using iTunes (ver. 5., 6, and 7) on several different Dell laptops and have consistently had trouble playing (and importing) CDs. When I insert the CD, the Gracenote (CDDB) window pops up and disappears very quickly (too quickly to read...) and the CD never appears in the left panel. When I Run Diagnostics I get the following:
Microsoft Windows XP Professional Service Pack 2 (Build 2600)

So, the CD is read in the drive, but it still never shows in the left panel to play or import. Windows Media Player will do it, but hey, I don't want to use WMP! I want to use iTunes! I have tried updating the Intel chipset drivers as well, no dice.
Any help would sincerely be appreciated.

Me too! I have just updated to version 7.0.2, and now iTunes won't recognize any Cd's I put in the drive to import. It hovers for a while at CDDB Gracenote and doesn't respond. Me thinks this is some sort of 7.0.2 gracenote issue. I've never had any issues with iTunes like this before. I am running bullguard version 6.1, microsoft defender, zone alarm, spyware doctor and spybot search and destroy and none of them have intered before. any suggestions?
I think this is disgraceful that iTunes can put out a new version of iTunes with so many inherent bugs. i count my self lucky that it hasn't deleted my library. i'm off now to get an external drive and back the lot up, because i don't have any faith in itunes anymore. i have 13,000 songs, so i'd be a little ticked off!

Intermittent : The term 'get-date' is not recognized as the name of a cmdlet, function, script file, or operable program.

I have developed a batch harness whereby all scheduled tasks (W2012) invoke a common powershell script that acts as a wrapper to all our housekeeping jobs.
The first step in the wrapper is to create a Transcript file using following code
if ($Host.name -ne "Windows PowerShell ISE Host") # Transcript does not work within ISE
$timestamp = (get-date -format "yyyy-MM-dd-HH-mm-ss.fff")
$path = "c:\corp\$timestamp" + "_$pid.txt"
Start-Transcript -path $path -append
As expected the folder contains files with timestamp & pid in name

Do I have to code defensively for base Powershell functions?

MacBook Pro running Leopard has suddenly thinks audio CDs are blank. Also not recognized in Itunes.

MacBook Pro running Leopard has suddenly thinks audio CDs are blank. Also not recognized in Itunes. What should I do to determine whether it's a hardware or software problem? Or is there something unusual about these CDs?

I have the exact same issue.DVD's work perfectly, but audio cd's have stopped working. I think it's pretty recent, but can't confirm it because i don't use audio cd's daily. So I think it might be software related instead of hardware related. I Have a Macbook pro 15" mid 2009 running the latest OSX release.

CD drive not recognizing new CDs

Hi, my Toshiba Qosmio X500 is not recognizing any CDs. I put a CD in and nothing happens, I go into my computer and there is nothing there, please help, what should I do.

Same problem here but I think mine was broken by the guys at the Genius Bar. My hard drive went out about a year and half ago and was replaced. After that my CD drive was scratching CD's. I didn't want to give up my computer again so I procrastinated and took it in about 4 months later and they said a bar had been bent and they had bent it back for me. They tried to tell me it was my fault. The tech guy put in a CD and it took a long while to read but then it showed up. That was the last time it worked. Of course when I got home to upload the music CD's I had purchased since then it wasn't working. I was so disgusted that I haven't gone back. Whenever I put a CD in the drive spins very loudly for about 20 seconds and then spits out the CD. And usually scratches it too. The work around I have been doing is putting CD's into my husband's desktop and then he shares that disk drive over our network so I can transfer files onto my computer. Would love to know if anyone has found out if Apple is fixing this problem (since it sounds like a defective piece of hardware) if the computer is still under Apple Care warranty. Thanks!

Time capsule works as wireless router, but intermittently stops backing up because it is not recognized

So here is the scenario. I just purchased a new 2T Time Capsule about a month ago. At some point, about a week ago it stopped working correctly. A few things that I've noticed:
1. The wireless router works just fine.
2. Every once in a while (more often than not) my computer (Mac book pro) will not recognize the time capsule and it will therefore not do it's wireless backup. I can no longer use it to store data.
3. What works? Unplugging the time capsule for about 20 seconds and then reconnecting seems to fix the problem, but will then the same problem will recur spontaneously.
4. Sometimes, I'll restart my computer and that will fix the problem, but again time capsule will drop off from the shared devices.
5. Interestingly, when TC is not recognized by my mac book, the Home Sharing feature of Apple TV also is rendered non-functional.
Any ideas? is it a hardware issue? If so, is it my Mac book or my TC or both?
Thanks for your advice in advance

I have seen a few posts on this one and the issue is very likely to be the way Auto channel changes take place.. for some unknown reason, the wireless can still connect as a router but the arp address is lost in the ARP table on the computer. So open a terminal and type arp -a soon after a TC restart when TM can see it.. you will see the TC MAC address listed. Once the TC is no longer recognised again do arp -a and you will find the TC is no longer listed. It is possible to force a static listing to the ARP table, but it seems to be much easier and better to simply lock the wireless channel.
Using the airport utility go to the TC setup and open the wireless area. Airport on the top menu.. wireless on the tab under that. where it says radio channel selection change to manual.. give it a fixed channel, for 2.4ghz it is best to pick the least used channel and you will need to use some site survey software to do this.. kismet, inssider for pc is superior to most Mac utilities at the moment. There are only 3 non overlapping channels 1, 6, 11 (12,13 outside USA). Pick one. I would also give a separate name to 5ghz wireless so it doesn't switch between the two.. that means you will have to change manually if signal drops out as it does more readily on 5ghz. The locking of channels seems to help the Mac not lose the MAC address in arp..though the actual mechanism is unknown to me.

My computer is not recognizing cds

When I put a music cd in the cd drive the computer tries to read it for about 30-40 seconds then spits it out regardless of the cd. These are store-bought cds not something someone has made improperly.

Zap the PRAM and Reset the SMC; then, try again.
