Lacie DVD burner - DVDs & CDs won't mount on the Desktop

Hi -
I've had an external Lacie Porsche DVD burner for about 11 months now. Two months ago, both CDs & DVDs stopped mounting on the Desktop. I've aleady verified that CD & DVDV mounting on the Desktop is selected in Finder General Prefs. All CDs mount fine when inserted in the internal CD burner drive.
The DVD burner shows up in ASP, iTunes & Toast as Ac NEC, model #2510A, I believe.
The Lacie product (model) # is 300759A.
Thanks, in advance, for any feedback.

You ought to try this as well on the hardware forum as well.

Burned archive CDs won't mount on OS 10.7.5

I have been archiving photos onto CDs for a few years, and most of them are fine. But there are 3 that won't mount (on 2009 iMac or 2007 MacBook both running OS 10.7.5), two from 2003 and one from 2005 (others from 2005 are fine). Does anyone have ideas about how to fix this? I've been googling for solutions without success.
Many thanks!

Additionally, if you must have them on CD or DVD, the only thing I would suggest is the rather expensive archive media:

I have burned some very important data as well as some one-of-a-kind foreign language movies to those DVDs. They as supposed to last 50 years or so.

Blank cds won't mount

Ever since I replaced my hard drive, blank CDs won't mount. Curiously, they are recognized by iTunes, but not for data purposes. I have to open disk utility to eject the disks each time I try. Any ideas?

I can grasp at straws as well as anyone.
Try changing the System Prefs/CDs & DVDs setting for blank CDs and determine if the computer responds correctly to any of the options.
I would also try logging out and back in. Or logging out and logging in as another user (create a new account if you have to).
If iTunes and Disk Utility see the CD when inserted, I am guessing you have a corrupted preference for System Prefs/CDs&DVDs. I'm not sure if there is a plist you can delete, or if even a PRAM reset might do it.

I have downloaded 10.5.8 combo several times and cannot get it to install because the disc won't mount or the installation gets hung up after restart. My current os is 10.5.1, and I am trying to upgrade to snow leopard. This is on a dual core macbook pro.

You don't need to update to Leopard 10.5.8 unless you want to keep Leopard. Upgrading to Snow Leopard requires that your purchase the retail install disk.
The following covers Leopard:
Some general advice on updating:
It is worth noting that it is an extreme rarity for updates to cause upsets to your system, as they have all been extensively beta-tested, but they may well reveal pre-existing ones, particularly those of which you may have been unaware. If you are actually aware of any glitches, make sure they are fixed before proceeding further.
So before you do anything else:
If you can, make a full backup first to an external hard disk. Ideally you should always have a bootable clone of your system that enables you to revert to the previous pre-update state.
Turn off sleep mode for both screen and hard disk.
Disconnect all peripherals except your keyboard and mouse.
1. Repair Permissions (in Disk Utility)
2. Verify the state of your hard disk using Disk Utility. If any faults are reported, restart from your install disk (holding down the C key), go to Disk Utility, and repair your startup disk. Restart again to get back to your startup disk.
At least you can now be reasonably certain that your system does not contain any obvious faults that might cause an update/upgrade to fail.
3. Download the correct version of the COMBO update from the Apple download site.
The Combo updater of Leopard 10.5.8 can be found here:
http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update
If you prefer to download updates via Software Update in the Apple menu (which would ensure that the correct version for your Mac was being downloaded), it is not recommended to allow SU to install major (or even minor) updates automatically. Set Software Update to just download the updater without immediately installing it. There is always the possibility that the combined download and install (which can be a lengthy process) might be interrupted by a power outage or your cat walking across the keyboard, and an interrupted install will almost certainly cause havoc. Once it is downloaded, you can install at a time that suits you. You should make a backup copy of the updater on a CD in case you ever need a reinstall.
Full details about the 10.5.8 update here: http://support.apple.com/kb/HT3606
More information on using Software Updater here:
http://support.apple.com/kb/TA24901?viewlocale=en_US
Using the Combo updater ensures that all system files changed since the original 10.5.0 are included, and any that may have been missed out or subsequently damaged will be repaired. The Delta updater, although a temptingly smaller download, only takes you from the previous version to the new one, i.e. for example from 10.5.7 to 10.5.8. Software Update will generally download the Delta updater only. The preferable Combo updater needs to be downloaded from Apple's download site.
Now proceed as follows:
4. Close all applications and turn off energy saving and screensaver.
5. Unplug all peripherals except your keyboard and mouse.
6. Install the update/upgrade. Do not under any circumstances interrupt this procedure. Do not do anything else on your computer while it is installing. Be patient.
7. When it ask for a restart to complete the installation, click restart. This can take longer than normal, there are probably thousands of files to overwrite and place in the correct location. Do nothing while this is going on.
8. Once your Mac is awake, repair permissions again, and you should be good to go!
If your Mac seems slightly sluggish or ‘different’, perform a second restart. It can’t hurt and is sometimes efficacious! In fact a second restart can be recommended.
9. Open a few of your most used applications and check that all is OK. In this connection please remember that not all manufacturers of third party applications and plug-ins, add-ons, haxies etc, will have had time to do any necessary rewrites to their software to make them compliant with the latest version of your operating system. Give them a week or two while you regularly check their websites for updates.
N.B. Do not attempt to install two different updates at the same time as each may have different routines and requirements. Follow the above recommendations for each update in turn.
Lastly, Apple's own article on the subject of Software Update may also be useful reading:
http://docs.info.apple.com/article.html?artnum=106695
[b]If you are updating Safari (or just have):[/b]
Input Managers from third parties can do as much harm as good. They use a security loophole to reach right into your applications' code and change that code as the application starts up. If you have installed an OS update and Safari is crashing, the very [i]first[/i] thing to do is clear out your InputManagers folders (both in your own Library and in the top-level /Library), log out and log back in, and try again.
So, disable all third party add-ons before updating Safari, as they may not have been updated yet for the new version. Add them back one by one. If something goes awry, remove it again and check on the software manufacturer's website for news of an update to match your version of Safari.
Most errors reported here after an update are due to an unrepaired or undetected inherent fault in the system, and/or a third party add-on.
Additional tips on software installation here:
http://docs.info.apple.com/article.html?artnum=106692
To reiterate, Input Managers reach right into an application and alter its code. This puts the behavior of the affected application outside the control and responsibility of its developers: a recipe for problems. That's not to say that issues absolutely will ensue as a result of Input Managers, but you, as a user, must decide. If the functionality of a specific Input Manager or set thereof is really important to you, you may well choose to assume the associated risk.
Again, the advice is to remove all Input Managers from the following directories:
/Library/InputManagers
~/Library/InputManagers
especially prior to system updates (they can always be added back one-by-one later).

CD-R not mounted on the desktop

Sinc ehte CD-R I'm use to use since years are no more mounted on the desktop i think i could have decided, by mistake, to flag the option as default not to mount them
If you see a dialog, you can choose an action from the pop-up menu and select “Make this action the default” if you want the same thing to happen every time you insert a blank disc.
The disc appears on your desktop."
Let's suppose i decided once by mistake NOT TO MOUNT the CD on the desktop, how can i come back and delete the choice i did?
Thanks

In Preferences, CDs & DVDs, simple select what you want to happen for blank CDs DVDs music, picture CDs or video DVDs.
It's all there. You can change it anytime.

When connecting to server the other computers will not mount on the desktop

Hello
I have three computers connected wireless and ethernet. When connecting to the imac and mac pro with my macbook pro the other computers will not mount on the desktop. I have never had a problem like this before.
The imac and mac pro will mount the laptop or imac and the imac will mount the mac pro and laptop.
When I connect to the server with the laptop I can access everything thru the shared folders but nothing will mount on the laptop desktop using the, connect to server.
External HD connected with firewire will mount and the internal cd/dvd will mount.
I have ran permissions repair on the laptop. Have I accidently changed some configuration I am not aware of?
Any help or advice is greatly appreciated
Thank You
Dick

Dick,
I know this sounds silly but while in Finder goto (Finder)/(Preferences) and then make sure your on the (General) tab, make sure all the things you want to show are checked.
If that doesn't help move the com.apple.finder.plist to the desktop you can find in in ~/Library/Preferences ( ~ = Your Home Folder), log out/log in, and see if that fixes the problem if not go ahead and move the plist file back.
hope that helps,

About cameras not mounting on the desktop in Tiger (10.4.3)

Information for those here who have problems with their cameras or chip readers no longer mounting on the desktop.
This has happened here too, with a Nikon D50 connected to an iMac G5 iSight 20". At first, I thought it was a lock file problem, caused by me forgetting and disconnecting the camera without first ejecting the desktop icon. But, I now think the problem is more likely caused by upgrading to 10.4.3, since I spoke with AppleCare today.
I was told that the 10.4.3 upgrade says (somewhere) that due to changes in iSync, cameras will no longer be mounted on the desktop. I made the observation that many users of digital still cameras prefer to transfer images from the camera (or chip) using the Finder. The operator said he would escalate this issue - he didn't know why this might have been changed, but seemed to understand that it would be an issue for a number of people.
Personally, I'm confused by the whole arrangement, which seems most un-Mac like: image handling prefs are actually set in Image Capture, despite the fact that the default app that launches when connecting a camera is iPhoto. Now, it seems, iSync is being brought into the frame (please excuse the pun!).
Why can't the action be defined in a General Preference pane, where it would be more easily found? Well, the answer is that it surely could be - and I would suggest that it should be. And I think the prefs should also include an option to have the camera/flash chip mounted on the desktop, for access in Finder too.
On a final note, the Nikon D50 is, I was told, not in the list of cameras supported by Tiger. Yet, when I checked with Nikon, they do not issue any drivers for the D50 and said that the drivers in Tiger are "D-series camera drivers" and, as such, are compatible with the new D50. Unfortunately, a lot of my time was wasted, because the AppleCare rep repeatedly wanted me to accept that the problem was due to the fact that this model of camera is not supported. This was despite the fact that I advised him of the fact that there are a number of threads here in the discussion forums, with users mentioning that they've had exactly the same issue with a variety of different cameras, of many brands.
I'll report back, as and when I hear anything further from the escalation of this issue.
Nigel

You have tried a lot of things, all correct, but have you repaired permissions since reinstalling Flash?
Repairing permissions is important, and should always be carried out both before and after any software installation or update.
Go to Disk Utility (this is in your Utilities Folder in your Application folder) and click on the icon of your hard disk (not the one with all the numbers).
In First Aid, click on Repair Permissions.
This only takes a minute or two in Tiger, but much longer in Leopard.
Background information here:
http://docs.info.apple.com/article.html?artnum=25751
and here:
http://docs.info.apple.com/article.html?artnum=302672
An article on troubleshooting Permissions can be found here:
http://support.apple.com/kb/HT2963
By the way, you can ignore any messages about SUID or ACL file permissions, as explained here:
http://support.apple.com/kb/TS1448?viewlocale=en_US
If you were having any serious problems with your Mac you might as well complete the exercise by repairing your hard disk as well. You cannot do this from the same start-up disk. Reboot from your install disk (holding down the C key). Once it opens, select your language, and then go to Disk Utility from the Utilities menu. Select your hard disk as before and click Repair.
Once that is complete reboot again from your usual start-up disk.
Also, how much RAM do you have? Some older G4's can struggle with today's streamed flash content.

CC Illustrator files (v17.0.0) won't reopen from the desktop. How can this be fixed?

CC Illustrator files (v17.0.0) won't reopen from the desktop. How can this be fixed?
Hmmm, the problem appears to have disappeared once I deinstalled Dreamweaver CS6. Coincidence?
Also our IT department sent me this, but no need for it at the moment:
Deleting the preference folder (in osx it's in "user/library/Preferences/Adobe Illustrator 17 Settings").
Illustrator will then create new preferences.

Seeing a camera mounting on the desktop

Hi, I've shot a 40 min video with a nikon coolpix but to import it, I've to go through Iphoto. The problem is that the file seems too long to be improted in Iphoto. I'd like to know how to do to see the camera mounting on the desktop in order to get directly from it the avi file.
May be you have another way to do it without opening Iphoto.
Thanx
Steve

As iBod pointed out Image Capture preferences determines what happens when you attach a camera to your Mac. Just like Safari determines your default browser.
I like to download my camera to a new desktop folder using image capture. I can then open iPhoto and select what I want to go to iPhoto. I keep the original download folders in a separate folder in Pictures to backup.

DVDs & CDs won't mount on my Macbook.

I have a 2008 Macbook that will no longer play DVDs or CDs. When the disc is inserted, the drive makes some funny noises (more than just the usual crunching sound and whirring) then after about 10 seconds the disc is ejected. I have tried several different discs all with the same result. I have tried inserting a laser lens cleaning disc and it gets ejected too. These same discs that I am trying to play worked just fine last week. I have tried modifying some settings in Preferences and I have restarted the machine as well as shut down and restarted. Nothing seems to help. Any suggestions? The OS X I am running is Snow Leopard if that makes any difference.

The gist of the topic surrounding compatibility of the Apple USB SuperDrive (recent version) with older models of MacBook/Pro, /Air, iMac (intel) that had built-in optical drives, is that the older models would see their internal drive as the correct boot drive for an OS X disc. And not see the newer optical superdrive, due to changes, as one. The older Apple USB SuperDrive model was different in this regard; as was the early model intended for MB/Air.
However, I've heard of brands such as LG who make a generic USB superdrive that is less costly and it has been said these can be used as an external USB boot drive for OS X discs.
In either situation, a superdrive's compatibility for simply playing or recording to media discs is one thing; being able to boot an OS X system on DVD media is another. So there is a gray area when interpreting this. I'd suspect a generic USB superdrive may be worth the effort due to the lower cost; should it not work out exactly, it will still work as a good player. It may also do OK even if the OS X may balk at recording media (had not read that it causes issues) in so much as a work-around would be to use other recording software to use the drive.
A standalone drive, if you talk to the vendor about your issue or need for compatibility, may be an answer; especially when the original internal superdrive has failed. This OWC page has a few different options; of course internal options need to match the computer specs. External options could work, however that's why I'd ask directly, by email or phone...
http://eshop.macsales.com/shop/optical-drives/superdrives/
There are a few items to note in this iFixit guide regarding the newest Apple USB superdrive that could make it worth consideration as a replacement, due to some kind of patch that may (or may not) work. Looks as though it could. Details and a method are referred to here:
http://www.ifixit.com/Device/Apple_USB_SuperDrive -- with more details about a workaround:
http://www.ifixit.com/Answers/View/23023/Can+I+use+the+AirSuperDrive+as+an+Exter nal+Drive+the+Mac+laptops
The method discussed in the above thread suggests a possible workaround, but may be too narrow to reasonably buy a new retail Apple USB Superdrive, to try it. The topic is interesting.
{Of course, there also are companies whose business is to repair and restore function to older Mac portables, and some are quite good at that; if you need an older model to continue use of software investment of a vintage era, compared to the latest newest models. OWC site has a few on occasion, & wegenermedia does, too; inventories vary. Or they could fix yours. There are times when it is good to have an identical spare computer; a backup device.}
There are a few options noted in following page, where LG, Samsung, & a few others are listed:
http://www.macmall.com/n/Best-External-DVD-Drive-Mac/macMainMenu-2286?q=macMainM enu-2286
Some users in the ASC discussions had good result from LG and Samsung models as external USB superdrives for use with older MacBook/iMac models whose internal optical drives had failed. Since the newest MacBook/Pro or /Air do not have optical drives, nor do the iMac or Mini, the newest Apple USB Superdrive would require a workaround to see if it could work. Some have done that, but I doubt they went out and bought the Apple model to modify it. First, it costs more than the other brands; and second, it is not recommended to modify the product because that likely would void Apple warranty.
Anyway, I'd consider a third-party name brand for the older product external superdrive replacement path; but the LG and Samsung may be able to work OK for burning discs, and to boot the computer from an OS X install disc. Some other brands of burners would prefer another brand of software to burn discs. •If you contact macsales/OWC, ask if they have a product that can use the OS X included drivers (so you install nothing) to burn DVD/CD, and about compatibility with commercial recorded discs; and also the question of importance with original install-restore or retail upgrade DVD, if they boot Mac System DVDs and support OS X like the original-internal optical superdrive.
Hopefully you can get a workable solution for your old MacBook.
Good luck & happy computing!

DVDs / CDs Won't Mount

Recently after burning DVDs - via DiskUtility and iDVD - burned DVDs will not mount: Instead after inserting and waiting the DVD simply is spit back out. Yes, I've run Disk Warrior; did fsck -y; Onyx.
What can I do now?

I've had the same problem. My SD will spit out the DVD-RW
from Staples. The drive does not show up in the HW section
of Disk Utility. This same DVD-RW works fine in my iMac G5.
(Only burns at 2x though)
I can use the drive to update/grade software using the CD
function. I can also play DVDs without issue too.
Arrrrggh!

DVD burned in tiger won't play on panther

Hi,
I have an iMac G5 with Tiger (10.4.2) in it. I just burned a DVD there and it plays fine on that computer and on my home DVD player.
However the DVD won't mount on my Flat Panel iMac G4 w/SuperDrive running Panther (10.3.9).
I have the latest software updates on both computers.
Has anyone come across this problem? Any solutions?
What other compatibility problems do I expect with this DVD?
I used to use the G4 for making DVDs that played on the G4 iMac, the G3 iBook, and other PCs. Will this DVD now work on all those other computers or is it only compatible with Macs running Tiger or worse yet, only G5 computers?

uh, chase, I think you're in the wrong forum.

WARNING! MEMOREX DVD-R keeps ejecting/won't mount

Ok..so I have an eMac (2004)
SuperDrive PIONEER DVD-RW DVR-107D
CDs & DVDs with data AND DVDs burned for DVD players DO MOUNT.
Then a DVD from Netflix loaded..so everything seems to work except DVDs burned to MEMOREX DVD-R.
A friend converted VHS stuff for me to DVD from a Panasonic VHS to DVD converter. Some DVDs mounted. The MEMOREX media he used did not. They do not want to mount.
So I will be testing other media again from this converter..But we have seem to have found a problem with MEMOREX media. (recordable 16x 4.7GB)
Also tried resetting the PRAM and looked all over for issues with my Pioneer SuperDrive. Found nothing
eMac Mac OS X (10.3.9) also have an iBook G4, G5 dual,

Memorex Media is Fair at best. Some of the older Optical Drives do not expieriance the problems that the newer drives have.
When you are burning be sure you friend has his settings correct for Mac and PC compatiblity.
Here is a Media quide to use when purchasing.
http://www.digitalfaq.com/media/dvdmedia.htm
Next be sure if you are using the newer high speed media that you read the back of the packaging and the media will burn at the lower speeds . It will read that this media will burn at 1X, 2X, 4X, 8X, and 16X. so no matter the drive you have it will burn this media.
Also, as you already know stick with DVD-R Media it is the most widely recognised and used, for computers and players alike.

DVD burned from img won't play in other players

In order to back up an old DVD I had to protect it from damage, I ripped it with handbrake and encoded it as a diskimage via iDVD. As the movie was 1.5 hours in length I used the professional setting under project info. After approximately 12 hours of encoding the disk image finished. I can open the disk image with DVD player on the mac and it performs perfectly. I used the disk utility to burn the disk image to a Memorex DVD+R without incident. This morning I tried the burned DVD in my xbox360 which read it as a mixed media disk and would not play it. Next I tried in my sony blu ray player which read it as a photo disk with no photos on the XMB.
What do I need to do to have the burned DVD work properly? Are the DVD+Rs bad or is it something with the encoding? Thanks in advance for your help. I am a pretty big novice to iDVD and the whole process.

To create an image file, launch Disk Utility and select File: New: Disk Image From Folder. In the window that appears, navigate to the desired folder (the DVD) and then click on Image. Give the image file a name, and click on Save when prompted. That’s it.
