Data DVDs Not Mounting

Hi there -
My Power Mac tower is now suddenly refusing to mount my data DVDs - all are discs of photos and other non-video files. All of these discs were burned on this machine. And all are DVD-R's, and different brands of discs.
Is this possibly an issue with my version of Tiger? (I'm on 10.4.11) I have been on this version for a while, and I can't say when this problem would have first started -- I don't think I've tried to read these discs in months.
Anyone have any thoughts that might help?
Thanks!
Tracey

Hi Tracey, and a warm welcome to the forums!
It may very well be the burner going out, & the CD & DVD parts use different lasers, as well as Reading & Writing using different circuits & voltages.
What happens? Do they get ejected? Are they seen if you open Disk Utility?
Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if things work OK in Safe Mode.
Then move these files to the Desktop...
/Users/YourUserName/Library/Preferences/com.apple.finder.plist
/Users/YourUserName/Library/Preferences/com.apple.systempreferences.plist
/Users/YourUserName/Library/Preferences/com.apple.desktop.plist
/Users/YourUserName/Library/Preferences/com.apple.recentitems.plist
Reboot & test.

Blank cds/dvds not mounting, iLife '06 will not install

After auto upgrades to Tiger v10.4.8 blank cds and dvds will not mount but are automatically ejected. I have a superdrive Sony DVD RW DW -U10A. It will recognize and read cds and dvds that have data. I also attempted to install iLife '06. The installer v 2.1.0 said it could not install. Somewhere I read that these problems are related to the upgrades from Jaguar. Any ideas--chattrod

You posted in the wrong forum. This area is for "G5" iMacs. Your system info confirms you have a G4 iMac.
You need to respost in the G4 iMac (Flat Panel) Forums where the knowledgeable users using the same model iMac as yourself hangout & will be able to help you.

CD/DVDs Not Mounting But Drive is Recognized / SCSI Card Not Seen

Apologies for this mess in advance, but I thought it was worth seeing if anyone had an idea of what to try on either of these two issues from a system software perspective before I start breaking the computer apart and tinkering with hardware.
My G4 is the 733 MHz model which first shipped with the SuperDrive. That SuperDrive died years ago and I replaced it with an HP DVD Writer 300n which worked fine up until some version update of 10.4 though I can't recall the specific version. In any case, now the drive will not mount any CD or DVD that I insert, commercially-pressed or otherwise. The eject key on the keyboard functions properly, the tray opens and closes without problem and when a disc is inserted the activity light goes on and the disc spins for a minute and all seems normal, but the disc never appears on the desktop nor in any Finder window. The drive is still recognized in the System Profiler and I've double-checked the CD/DVD settings under System Preferences to verify that nothing is set to ignore there. I suppose it's possible the laser suddenly went bad, but as I said, the symptoms showed up following an update (though it was a while ago and at the time I had no need for a optical drive on this computer so I didn't address it then).
The second issue I discovered when I attached an external optical drive via the SCSI port I hadn't used in many years. That drive wasn't recognized at all and when I looked in the System Profiler the SCSI card isn't listed under PCI Cards. Is there a generic SCSI card driver I might be missing under OS X or will I need to open up the computer and determine which card I actually have in there?
Any suggestions would be appreciated and hopefully I've provided enough information to make that possible.

Hi K Roth, and a warm welcome to the forums!
I find Optical drives fairly short lived myself, but on the Internal, you might try PatchBurn...
http://www.patchburn.de/
Do you have another Mac with Firewire and a good optical drive?
If so you can boot the Other Mac into Target mode...
http://docs.info.apple.com/article.html?artnum=58583
Boot this G4 with the Option key held down, see if the Install Disc in the other Mac shows up as a boot choice.

Data DVD Not Reading On PC

Hi:
I'm preparing to send off pics I took and imported into iPhoto. I then exported them to a folder, and since there are more than will fit onto a CD, used Toast Titanium 7.0.1 to burn a data DVD with the Mac & PC format tab selected. The DVD will either not show up in one PC I tested on, or on the other it says the files are unreadable. Any suggestions TIA.

Did Toast compress them in order to fit them all on a single DVD? You might try using the Finder to burn the disk and use multiple disks to do the job. I've never had any problems with my burned data disks and PCs.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.≤br>
Note: There now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

Data dvd not recognized

Hi
Wonder if anyone can help...
I have recently had a show-reel put together and they have sent me a copy on a data dvd with AVI and MOV files on it. This is so I can burn it and upload it to websites etc.
When I load the disk it doesn't seem to be recognized. There is no icon on the desk top but The iDVD application does automatically open up though, however I can't find the files anywhere.
I have looked in disk utilities and the disk is listed but it wont let me verify it.
Does anyone have any ideas about why this might be and what I can do it about it.
I want to try and burn a couple of copies so any help would be great.
Thanks

Thanks for confirming that Import is correct.
When you say the Capture Scratch folders only hold captured material, does that include Imported material? And if so, when I look in the Capture Scratch folder and see not QT files (as I have seen in the handful of previous projects I have attempted) but small "FCE document files" then I do have some kind of problem, right? I'm just trying to figure out where to start in understanding this, and it seemed to me the external hard drive source was the new variable here; that maybe there was something I had missed in terms of what was required when using the XHD as a source instead of my own camera capture. If that is not the case-- that is, if a QT file is the same whether brought to the system through Capture or found on an HD and imported-- then I have to figure out what I did to screw up the Capture Scratch function. I have not done any render effects. I'm just setting up. I've not done much of this and none at all recently, so operator error is certainly possible. I'll reproduce the export and see if I can refine the settings. Thanks for your patience and thoughtful assistance.

Data DVD not recognised

I burnt my images on my old PC on a DVD, marking it as a data DVD and making it presumably compatible with other systems. It can be read by other PC's, but not by my new MacBook. It marks it as an unburnt CD!!
It reads CDs & DVDs just fine.
Please, if you have any ideas...
MacBook Pro 15" @2.1GHz Mac OS X (10.4.7)

Sonic is the name of the company (they bought Roxio), not the application. But anyway, I have Sonic DigitalMedia Plus on my Dell and I see an option to burn as Data > "Direct to disc" which would indicate it is probably using packet writing (similar to writing to a floppy or DVD-RAM), then they have the option to click "Make compatible" in order to share the disc. Maybe you didn't click that? If your other PC's also have the same burning software, they would be able to read it even without making it "compatible". Or make sure you are clicking on "Data Disc" instead when creating new discs.
Let me know how you made out.

MBP cd/dvd not mounting

I have just received my MBP back from the Genius bar where they had to replace the keyboard due to the left command key stop working.
I just inserted a music CD into the drive, the drive accepted the CD and I could hear the disc spin, but it does not mount to the Mac.
According to the Mac there is no CD/DVD onboard. Also I am unable to eject the CD...

CDs/DVDs Not Mounting

I fear my superdrive is failing again. In three years, this is the 3rd drive I've had--unfortunately it's now out of warranty.
I barely use the drive, but I seem to be going down a road that's familiar.
My Pioneer drive is recognized the hardware profile and by Patchburn, but putting any CD or DVD (even Apple's startup DVD) results in absolutely nothing mounting.
I've tried different users, I've tried zapping PRAM and throwing preferences out, but still no luck. I also haven't installed anything lately to prompt this.
Any thoughts for fixing this?
And if not, can anyone recommend a good EXTERNAL DVD burner that will work well with my G4 MDD? I'm not installing another internal one at this point...
- N

I put a Pioneer DVR-111D in my MDD G4, which came with only a Combo drive (now my 2nd optical drive). No problems with it, but then I'm running it in Tiger, which seems to make a big difference in component compatibility issues.
Those Pioneers are going for less than 50 bucks at numerous on-line retailers. External DVD burners are usually in 3 digits.

Data DVDs not reading correctly

For a while, I had been backing up data to DVDs, and I had never experienced issues retrieving the data from those DVDs later. However, now, when I try to retrieve data from DVDs, some files will copy correctly, while others will receive an error saying something along the lines of "incorrect permissions." I've attempted to repair disk permissions before, to no avail. I suspect this isn't due to the actual burning of the discs, because discs I haven't burned experience the same errors. (For example, I can no longer install Command and Conquer 3 because the installation process -- drag and drop -- fails with the same error as before).
Is there any history of this occuring? And if so, is there a solution, or do I need to get a new disc drive? Many of the files I can't retrieve are relatively important, and since most Apple-supported games are installed via drag-n-drop, I worry Command and Conquer 3 will be the last game I ever buy unless I get this fixed.

ASM not mounting after reboot of external storage

I have a setup with 4 internal drives and 12 external drives(external storage, multipath). The diskgroup was orignally created on the 4 internal drives and then the disk group altered to add the external storage. Everything was fine until the external storage array got powered down. Then we rebooted both boxes and ASM did not come up. I also see the HEADER_STATUS as UNKNOWN for all the external storage drives.

Burn to dvd not working

I am new to Final Cut Pro. I created a project, then burned it to a dvd with no problem. I later edited the project, then tried to burn that to a dvd and it will not burn.
I have no idea what I am doing wrong. With the project selected, I insert the DVD and wait for Finder to recognize it. I then go to Share>Burn DVD. I used the default settings both times as far as I know. There has to be a setting or something that I am missing. I am using a new DVD with nothing on it, not the same one as the first time.

Sounds like you made a data DVD, not a video DVD that will play in a DVD player or in a computer optical drive. (And I had read your initial post to mean that your disk was recognized in the Finder.)
If you do want a video DVD, then use Share>Burn DVD. If you want a data DVD, export a movie…using say, the Mac & PC setting in Apple Devices and then burn it in the Finder.
But I'm getting ahead of myself…which kind of DVD do you want?

Data DVD made from PC not mounting on OS 10.4.8, Any Ideas?

I am having issues with the mounting of data DVD's burned from a PC using Roxio mounting on my PowerBook. CD's mount just fine. Whst disk settings should I have when I am burning? The same disks that will not mount on the PowerBook do mount on a G5 desktop.

Welcome to the Apple Discussions
There are so many different codecs for video that you've landed on one that doesn't have a mac version installed.
First port of call, the Pentax site and see if they have an updated version for Mac.
Second, try install Perian: http://perian.org/ It's a collection of Codecs for QT that might help.

You could've backed up your iPad prior to the "forced" upgrade which, by the way, you could have cancelled. iTunes doesn't upgrade your iPad, automatically, on its own. You had to click the Upgrade button to initiate the upgrade. You didn't have to do anything with that button. You can just leave it be.
iOS 8 is garbage on iPad 2 and 3 and even though iTunes keeps giving me the Update button option, I continually choose to ignore it.
Ignoring the Upgrade/Update button doesn't affect the normal iTunes/iDevice syncing/backing up operations.
You could've just left that button alone.
When was the last time you backed up your iPad?
While there is no way way to revert to a previous iOS version once you upgrade your iDevices iOS, iTunes saves multiple backups of your iDevice and if you backed up your iPad previously to this latest activity, you should be able to restore your iPad from an older backup that should appear by date when you plug your iDevice into your Mac, was for iTunes to launch and sync your iPad, then cancel the backup in progress and use the Restore function in iTunes to restore your iDevice from another previous backup version date.
If your current version of iTunes doesn't recognize your iPad2 under iOS 8, you need to check the iTunes update feature, in iTunes or in OS X Software Update feature in OS X Preferences panel to see if there is a iTunes update available for OS X 10.6.8 Snow Leopard.

CD & DVD Blanks do not mount for burn in OSX 10.6.6

This is an issue with 10.6.6 or possible earlier update. I can mount and burn CD's and DVD's using 10.6.0. I have a disk recovery firewire external harddrive that when I use for diagnosis and repair. This has 10.6.0 as its system. When booting from this system I have full mount and burn functionality. Reboot to the system on my iMac results in the problem below
I am unable to burn CD'd and DVD's. I insert the disk, it goes in and remains in but then - Nothing. My prefs are set to Ask what to do, but none of the pref options have any impact. I can then eject the disk using the eject button. Disk Utility and System Profiler shows the Optical drive as
Media:
Type: CD-R
Blank: Yes
Erasable: No
Overwritable: Yes
Appendable: Yes
Write Speeds: 8x, 16x, 24x
If I have a CD-R in the disk- so the drive is clearly identifying a blank.
Inserting a DVD+R returns
Type: DVD+R
ID: RICOHJPN R02
Blank: Yes
Erasable: No
Overwritable: Yes
Appendable: Yes
Write Speeds: 2.4x, 4x, 6x, 8x
The optical drive is recognising the disk.
But the burn function is not booting.
This is independent of brand of disk. It loaded and burnt disks successfully previously and seems to be related to an OS update. I do this so rarely that I cant really date the start.
I am able to insert and read any type of burnt or recorded disks, CD's, DVD's and mount them.
Have repaired permissions and trashed anything that looks like a CD pref. Have the same problem on my wife's side so it looks like it is not limited to my user account but is a a high level system issue.

Funny, since the upgrade from 10.6.5. to 10.6.6. I too have problems with a formerly more or less perfect system.
Not my finder is freezing but I cannot read or write CD-RWs anymore and I've just discovered a data DVD which the MacMini will not read.
This was NOT the case before the update and it is not a problem with the CD's or DVD's as they can be read via an external drive.
What the **** have you done, Apple, to screw up my computer hardware through a software update?! Huh!?!?!?! FIX IT!!
(Really, I'm done with System upgrades. From now on, if the system runs well, no updates anymore. Not even if it's an "important security upgrade". Screw it. I'm speechless.

One of my partition is not mounted. I can't mount it, can't repair it. I have a lot of data in this partition. I can't erase it, how can I do now? pls help me.

No way around this. Your phone has to be restored using a computer running iTunes. Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.
