Superdrive Sometimes Failing to Recognize DVDs
I've had my MacBook Pro for about 15 months and the Superdrive is now sometimes failing to recognize blank media, or ejecting commercial DVD's after playing the movie for a few minutes. Obviously the warranty has expired and I'm thinking of buying an external drive if the problem can't be fixed inexpensively. Any suggestions as to how to resolve this problem?
Thanks in advance.
Yes, I am having same problem. After updating to OS 10.5.2, my SuperDrive in my MacBook 2.2 GHz Intel Core 2 Duo will not play any DVD or Enhanced CD. (It will play audio CDs.)
For me, this is DEFINITELY an Apple software/firmware issue. When a DVD wouldn't play in my MacBook SuperDrive, I would instead use my MacMini successfully, which was running OS 10.4.x. I recently updated the MacMini by cloning my MacBook to it, and viola, succeeded in replicating the exact problem.
Also curious, my MacBook SuperDrive almost worked the first time I put my first DVD into it. DVD Player asked to set the region, which I did. It then refused to play the DVD or any other media DVD/CD subsequently.
I have no solution yet, but will share with all when I do.

Photoshop CC sometimes fails to recognize Nvidia card (GT 730M)
I run Photochop CC on my laptop and Photoshop sometimes fails to recognize Nvidia card (GT 730M), and I get an Intel driver crush notification.I set the Nvidia cardas prefered one for Photoshop and it still fails. Drivers are up to date. Any way to fix the issue?
If the Intel is the onboard graphics processor you could try disabling it in Device Manager and BIOS, and let the Nvidia card operate alone..

Anyone else seeing this - iDVD 08 *sometimes* can't recognize a superdrive
Anyone else seeing this - iDVD 08 sometimes can't recognize a superdrive in my 1-month old iMac
The error is "Your Macintosh does not have a supported SuperDrive. Please note that while you will be able to work with iDVD projects, you will not be able to burn a DVD disc."
Funny - it never said ths with iDVD 06
I'm seeing this about 20% of the time when opening iDVD.

Everytime I try to insert a DVD (feature film DVD) into my Superdrive, it fails to spin up and ends up spitting the disc back out. After 5 or 6 attempts, it finally spins up and mounts the disc. Why is this???
Has the drive always done this or is it new behavior? Which Superdrive do you have?
If this only happens with commercial videos, are they perhaps
rentals? Rental dvd's can be in pretty wretched shape and different drives can compensate for this to different degrees.
Some drives are better readers with better error correction
circuitry.
If they are discs that are in perfect shape I would wonder about the dvd read assembly. You could try a cleaning disk.
It could just be that the read assembly on the dvd side is bad. Not an uncommon problem (I had it with the original Sony drive in my MacPro and Apple replaced it > haven't heard of it happening much with the Pioneer drives).
Have you tried reading non-video discs with the MacPro that were burned by another machine? A bad drive can often read its own burns but not those made on another machine. -
W500 w/ Windows 7 64-Bit Ultimate fails to recognize some audio CDs
My DVD/CD drive (a HL-DT-ST_DVDRAM_GSA-U20N) in my Lenovo W500 laptop (running Windows 7 64-Bit Ultimate) fails to recognize some audio CDs.
It recognizes most audio CDs, but a few are not recognized by Windows 7 itself, or by any other program on my computer.
These CDs are recognized by other Windows 7 computers.
I don't think that it's a copy protection issue, since the CDs don't mention any copy protection scheme (and also since they work on other Windows 7 machines).
One CD that wasn't recognized by my machine was the second CD from a two CD set (the first CD was correctly recognized).
I have the latest updates for Windows, and all my programs, drivers, BIOS & firmware.
Thanks.What kind of behavior are you getting from the drive? If it's spinning up, down, and up again your lens might be dirty or the drive could be failing.
If you do clean the lens, be careful. Do your research first or you might make it worse.
Edit: Replacements are:
42T2511 or 42T2541 (DVD)
42T2543 or 42T2513 (DVD/CD-RW combo)
42T2545, 42T2515 or 42T2551 (DVD-RAM/RW)
You can get the 42T2543 for $23 and the 42T2545 for $45 on eBay. -
Scandisk or defrag fail to recognize hd volume
hello all, and happy holidays.
i've had this issue b4 but didnt pay too much attention to it, but now it has happened again so i am a bit bothered.
i have seagate 7200.7 120GB sata drive with ncq hooked to the nvidia sata controller #2.
The drive has 8 volumes (c-j), c,d,e,g,h are ntfs, the others fat32.
Sometime when my computer hangs and i've to reset it, scandisk fails to recognize some volumes (totally random this time f,i, always fat32) as valid win xp volumes.
I can still open these volumes and read and write to them, but cant run defrag (i use disk keeper pro) on them, or for that matter anyother hdd tools like windows scandisk etc.
Now when ever i reboot, scandisk kicks in complaining that it cant scan non-xp drives.
My options include turning off scandisk, reformatting (loads of data on them, really not a good option), find out whats causing it!!
So anyone here help me work on option three
Rest of the system is in the signature.
thanks.4184
Hello again tcdm1972,
This quote from a MicroMat technician is misleading and makes me wonder about abusingly promoting defragmentation (and using their products) as so necessary.
Yes, in certain rare cases one might benefit from defragmenting HD and HD free space, but in Mac OS X it is not so black and white question.
- In the more general usage of Mac OS X, defragmentation is actually counter-productive and defeats the very clever way Mac OS X has to rewrite every file on-the-fly onto the best possible location at this very moment, each time an application uses it.
Best location on the hard drive varies, depending on many more criteria than the simple contiguity.
About the term "optimization" in Apple software installs:
I find it misleading too, as all it optimizes is the launching of applications in Mac OS X
(it's the "update_prebinding" command really, nothing to do with defragmentation).
About OnyX, Yasu etc:
These too are small utilities to run quite harmless Terminal commands. They don't play in the same fields, nothing neither to do with defragmentation.
DiskWarrior too has yet another approach: Directory handling.
So, your original question about using iDefrag:
On their website they state
"To defragment your boot volume, you need to boot from a different volume"
as I said.
In your case, the solution is clear:
since you have two boot partitions on your HD,
- boot from Partition 1 to defrag Partition 2,
and
- boot from Partition 2 to defrag Partition 1.
That is, a copy of iDefrag installed on each of your Mac OS X volumes.

Hello, I have an IMAC (OS X version 10.8.3)
And when I put a blank disc (dvd+R 8.5gb DL), it's not even shown in Finder!
So, well, when I try to burn any files on it, it says:
"the burn to the SuperDrive drive failed. the burn failed because of a medium write error."
Please, help to solve my problem. I'm Russian & and it's really hard to find any help on Russian apple forums.

My MacBook Pro's internal SuperDrive has stopped recognizing CDs/DVDs after Yosemite install
After upgrading to Yosemite, my MacBook Pro's (early 2011) internal SuperDrive has stopped recognizing CDs/DVDs after Yosemite install. It takes them in and will eject them with the keyboard button, but they will not mount. Disk Utility shows the SuperDrive and shows the inserted media, but will not mount the disk. That button is grayed out. Please help! I still have training libraries and music I access on such media. Thx!
UPDATE: I discovered some forum posts about a similar issue with Mavericks that recommended re-installing the system to fix the problem. I realized that I rarely restart my computer unless there's an update that requires it, and decided before undertaking a full re-install of Yosemite to simply restart my computer again. THIS WORKED! The SuperDrive is now mounting CDs and DVDs. Not sure what the issue was, but if anyone else has this issue I hope this will save you hours of frustration.

Xterm sometimes fail to wrap when typing
When typing a long command (beyond the window edge) xterm will sometimes fail to wrap to a new line and instead begin writing over the current line. It's like it does a \r (carriage return) when it should have done a \n (new line).
The result is sort of what you'd get if you did 'echo -e "SOME_COMMAND_BLAH_BLAH_BLAH\rTHIS_SHOULD_BE_WRAPPED"'.
Of course this scrambles everything I do to an extend where xterm becomes unusable and often I have to close the corrupted xterm and open another. It's really starting to annoy me. I can't image what might cause this, but the problem seems to come up when I've been using the xterm for some time (some different tasks). Newly opened xterms are always fine.
Last edited by Lars Stokholm (2009-05-04 14:28:07)Use 'reset' to fix a "broken" terminal instead of opening a new one, this should ease things. Terminal state can be altered by certain control sequences/characters, e.g. if you cat a binary file you're likely to end up with a terminal that needs a reset. Other than that, a bad PS1 string may cause readline to get confused about the available line space if escape sequences are not wrapped in \[ and \].

At boot time (toshiba u300) alsa (or kernel maybe) fails to load sound.

I've followed this topics without luck.

First I worked around alsa sound state, it doesn't work, then I tried to point my laptop model in «/etc/modprobe.d/alsa-base.conf» file:
options snd-hda-intel model=toshiba
options snd-hda-intel index=0
options bt87x index=-2
options cx88_alsa index=-2
options saa7134-alsa index=-2
options snd-atiixp-modem index=-2
options snd-intel8x0m index=-2
options snd-via82xx-modem index=-2
options snd-usb-audio index=-2
options snd-usb-caiaq index=-2
options snd-usb-ua101 index=-2
options snd-usb-us122l index=-2
options snd-usb-usx2y index=-2
options snd-pcsp index=-2
options snd-usb-audio index=-2
And last I've tried to load Realtek modules in «/etc/modules-load.d/alsa.conf» file:
snd
snd_hda_intel
snd_hda_codec
snd_pcm
snd_page_alloc
snd_timer
snd_hwdep
snd_hda_codec_realtek
And here is that commands shows this sesion:

My next step is go into kernel but I think it's better to ask here first.
I have to say that before Arch it had installed Ubuntu 10.04 with OSS (problems with keyboard sound keys with alsa), lately before change to Arch I must to restart sound system before it works frequently with this procedure; «soundoff», then «soundon» absolutly freezes the laptop so I had to turn off it and turn on again, then «rm /usr/lib/oss/starting», and last «soundon», then it sometimes works.
Now my only way to have sound is to restart the system time and time again until it works.
Thanks for your advices.

Blacklisting [https://wiki.archlinux.org/index.php/Ke … acklisting]
Blacklisting, in the context of kernel modules, is a mechanism to prevent the kernel module from loading. This could be useful if, for example, the associated hardware is not needed, or if loading that module causes problems: for instance there may be two kernel modules that try to control the same piece of hardware, and loading them together would result in a conflict.
Some modules are loaded as part of the initramfs. mkinitcpio -M will print out all autodetected modules: to prevent the initramfs from loading some of those modules, blacklist them in /etc/modprobe.d/modprobe.conf. Running mkinitcpio -v will list all modules pulled in by the various hooks (e.g. filesystem hook, SCSI hook, etc.). Remember to add that .conf file to the FILES section in /etc/mkinitcpio.conf (if you have not done so already) and rebuild the initramfs once you have blacklisted the modules, and to reboot afterwards.
