AFTER 10.5.4 UPDATE "MEDIA NOT RECOGNIZED" WHEN BLANK DVD ON DRIVE

Hi, after update 10.5.4 my CDs and DVDs will be read and play in the Optical Drive, But when I insert a blank one, any kind, the finder will open and when I select to mount it "media not recognized" comes up. I have the same DVDs that Ive been burning to till this update with no problem at all.
I already did permissions repair.
Please help.
Many Thanks!

I have a problem pretty much like that too, I updated my mac, and now my superdrive won't read my discs, but unlike yours, it spits the disc out.
I did find out that it can recognize DVD +R, sometimes, but it can nolonger recognize DVD -R.
Also my superdrive makes a sound like this: http://www.imeem.com/people/2tOboJ/music/gQwemcsY/superdrive_problemwav/
Sorry if I'm hitching on your post Alex, I also have another problem, and that is I can see the "reply to this post" icon but I cant see any icons that say "post new topic" anywhere, I wonder why. =(

My imac is not recognizing any external dvd writer drive. I have imac with Core i7 and Mac OS 10.6.8. I have tried external dvd writers from Samsung and Amazon Essentials but the computer does not recognize any of them. Which Dvd writer is compatible?

I have an external firewire burner; it never shows on the desktop unless I insert a CD or DVD - that icon will then show (if I have my preferences set to show those on the desktop). Hae you checked in Disk Utility (Applications > Utilities) to see if it is listed under drives?

Logic Pro 7.2.1 Update is not recognizing my 7.2.0 app. HELP!

grrrrr, this is so frustrating!
Logic Pro 7.2.1 Update is not recognizing my 7.2.0 app. Any ideas?

To prevent cheating, the updater checks the receipts
first — receipts files look like regular package
files, but they're actually a list of pointers to the
files installed from that package, together with
their attributes: location, checksums, owner,
permissions, and so on... That's how the repair
permissions function works.
If you messed with your receipts folder, you may be
out of luck: in this case, re-installing everything
will rebuild the receipts and the updating
should take place.
Yet another option would be to use Pacifist:
http://www.charlessoft.com/
• it allows the user to create receipts for [.pkg]
packages
• it can be used to force installation of any file
from a given package
Be aware that Pacifist doesn't run any of the
pre-install, post-install, pre-upgrade, or
post-upgrade scripts, doesn't check already existing
receipts, and doesn't alter the permissions
afterwards, so you'd better know what you're doing...
nice illustration on the repair permissions....

[SOLVED]Hard Disk not recognized when installing

Hey all, I'm just starting with Arch and I've had some trouble installing it on my Acer netbook.
My first installation went well except that I had forgot to download the wireless tools so I decided to do a fresh install as I had no access to a wired connection at the time. The second installation attempt must have had some error on my part as Arch failed to start after selecting it from Grub, saying that the kernel was not available/not recognized.
Now my subsequent attempts at installing have failed because the hard disk is not recognized when running either cgdisk or cfdisk. Instead of showing my hard drive partitions after running
cfdisk /dev/sda
it shows my usb drive. If I instead use
cgdisk /dev/sda
it displays an error saying that the disk is damaged or not recognized. When I first saw this I thought my disk was failing, so I tried #! to see if it would show the same error, but it was able to recognize the entire disk and install correctly. Now, even after having the entire disk formatted as ext4 with #! installed, cgdisk is still giving me the same error about a damaged disk.
Am I doing something incorrectly or is there a fix for this? I haven't been able to find any information about this after a good while of searching.
Thanks for your help.

If you mean by trashing the USB flash drive, that it will delete all data and partitions on the selected drive it is correct, because:
dd if=/dev/zero of=/dev/$disk bs=4096 count=1
- this will delete all partition-table data
sgdisk -o /dev/$disk
- this will clear out all data. This includes GPT header data, all partition definitions, and the protective MBR.
/dev/$disk
- this will make you enter ncurses-based GUID partition table (GPT) manipulator, where you can create new partitions
You should only do this if you are certain of what disk it is.
Now if when you said this, you were meaning it will became broken, then it may be a special kind of usb drive because i've donne it many times and i've not broken any.
srs5694 wrote:My guess is that either your hard disk has become /dev/sdb (this can happen in some cases; disk identifiers aren't really fixed) or you're missing a driver for your hard disk controller because you've booted a different kernel or a different initrd file. Another possibility is that there's a hardware fault -- probably a loose cable -- that's preventing the kernel from seeing the disk.
If the usb drive is not where you installed arch, then you need to find if there are more recognized drives:
lsblk | grep disk
And see the uuid of the root partition you want, and add it to your bootloader boot line:
blkid /dev/sdxx

Try

I would start with
Removing and Reinstalling iTunes, QuickTime, and other software components for Windows XP
or
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
New cable and different USB port?
Runs this and see if the results help with determine the cause

After the latest OS update, Safari locks up when trying to flip back to the previous page

After the latest OS update, Safari locks up when trying to flip back to the previous page using the two finger sweep.

Try these in order testing your system after each to see if it's back to normal:
1. a. Resetting your Mac's PRAM and NVRAM
    b. Intel-based Macs: Resetting the System Management Controller (SMC)
2. Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
     Boot to the Recovery HD: Restart the computer and after the chime press and hold down the
     COMMAND and R keys until the Utilities menu screen appears. Alternatively, restart the computer and
     after the chime press and hold down the OPTION key until the boot manager screen appears.
     Select the Recovery HD and click on the downward pointing arrow button.
3. Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the Utilities menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
     Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).
4. Reinstall Lion/Mountain Lion, Mavericks: Reboot from the Recovery HD. Select Reinstall Lion/Mountain Lion, Mavericks from the Utilities menu, and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
Reinstall the 10.9.2 update: OS X Mavericks 10.9.2 Update (Combo).

Disabled ipod not recognized when plugged back in to itunes.

Daughter's disabled ipod (second time) is not recognized when we follow instructions to enable it and plug into itunes.

HT1808 is the article you need to follow. You need the section labeled "Placing the device into recovery mode."
You need to power the device off. Once the device is off press and hold the Home button or the button on the front of the device and while holding the Home button plug in the device and continue holding the home button until you see the image below.

Is the iPod Touch specifically stated as being compatible? Have you tried to perfrom a hard reset of the iPod with it still connected? To do this, press and hold both the Sleep/Wake and Home buttons together long enough for the Apple logo to appear.

Can anyone point me in the right direction for the link to download Acrobat 9 Standard? I found the link to download 9 Pro but not standard. Old computer crashed and new computer does not have a CDR/DVD rom drive.

Can anyone point me in the right direction for the link to download Acrobat 9 Standard. I found the link to download 9 Pro but not standard. Old computer crashed and new computer does not have a CDR/DVD rom drive.

Hi,
Standard or Pro would be licensed through your serial number, the download link and downloaded file would be the same for both of them.
Pro or Standard would be determined after you put in your serial number.

My iMac will not recognize a blank DVD-R that I am trying to burn. It also won't eject unless I "shut down"

My iMac will not recognize a blank DVD-R that I am trying to burn. It also won't eject unless I "shut down" and restart while holding down the mouse button. Anyone have any remedies?

I ran into a similar (identical?) problem. I inserted a DVD-R and my imac would not recognize it. The only way to eject was to do a restart. I tried some of the SMC reset stuff. That didn't work. I came across another thread on macrumors (http://forums.macrumors.com/showthread.php?t=336501)
that solved my problem.
I have an external Western Digital Passport drive that I use for timecapsule. It turns out
there are two files that WD adds to the /Library/LaunchDaemons that interferes with the
SuperDrive. I removed the WD files from the LaunchDaemons directory and everything works fine
now. Again, refer to the macrumors thread for more details.
The files I removed from the LaunchDaemons directory were:
com.wdc.WDDMservice.plist
com.wdc.WDSmartWareServer.plist
..yes I had installed the WD backup software to see if I liked it....I did not, but didn't realize this files would cause a conflict with the SuperDrive.

Hi,
You can get to the music folder when assigning ringtones.
When you edit or setup a contact you assign a ringtone.
Scroll all the way to the top in ringtones, and browse. You can
get to the music directory to assign a song as a ringtone.
I use "Truckin" by the Grateful Dead as my phone ringtone!
Here are the correct directories that should be on the media card,
and device memory. This is where Blackberry looks for the files:
