Disk Images from DVD-R

Today my attempt to make an image from a home-made (& finalized) DVD-R failed with an "input/output error", which was presented when Disk Utility had finished reading the DVD-R into memory. (The DVD does also play fine on this G5.)
I was surprised, as I've done this just once before with success.
Is it possible that this is in fact due to the recording mode originally used to make the DVD-R? I'm not sure whether I used SP (2-hour) or LP (4-hr) for the one that worked, but I do know that I had used LP for the DVD that I've tried to make an image from tomight. I don't really want to have to sit through all the tapes to make the 4 hours again onto two new 2-hr DVDs
Hopefully someone will know if this is the problem, in which case I shall resign myself to the task, but if there's any chance something else is at fault - well, I look forward to your advice!
Many thanks,
Blackie

Yes, I did finalize it in the Panasonic, thanks, Ron. However, I note that I did have some difficulty - it failed the first time, but was successful the second time.
When attempting to "create image", initially I left the format selection on whatever it defaulted to. I then tried again with read/write.
I've just tried "replicating" your
issue (using a disc recorded from television on our
own Panasonic "standalone" in "LP" mode).
Brilliant, thanks - at least that clears that part of my question up
Any possibility that the disc you were trying to
copy from is slightly dirty or damaged? You might
want to simply repeat the attempt after giving the
disc a gentle clean.
Ah, now this sounds worth following up, especially given my comment at the start... So, I shan't try using DVD master, but I shall try cleaning and having another go with the default setting.
As I understand it, my Toast Lite won't do DVD-Video, and I've not yet had a need for DVDxDV though I have heard many good things about it, for when I find I do have the need So in the short term, if I can get the process to work via Disk Utility for this one DVD, I'll stick with that
So, I have something to try before I mark my question as solved, but I think we are probably getting there!
A thousand thanks,
Blackie

Disk Utility will sometimes refuse to make image from dvd disk

Our company puts disk images of media collections on a central server so that they are available to all the staff. But, recently I keep finding disks that refuse to be copied as a disk image. The Disk Utility runs for just a few seconds rather that the usual 20-30 minutes and the final disk image is only a couple of KB of data. I've tried the disks on multiple computers with the same results. All our macs have the same OS so I've been unable to test if this is an issue with the current OSX.
I thought there might have been some sort of data protection put on the discs, but was surprised when disks from the same collection of media would have different results.
These are not Video dvds, but rather standard UDF data discs, being copied to a network drive.
I'm able to manually create an empty image and copy in the data but this takes much longer.
Any help would be appreciated.

I was having similar problems, although I don't think my issues was related to a double-layer DVD. What worked for me was selecting File > New > Disk Image from Folder. Select the DVD in the file open/save dialog with the same options you used before (e.g., DVD/CD master, etc).

Creating a Disk Image from Compressor Fails

Hpefully some one can help me out here.
Here's whats going on and I've tried this on 2 different systems (iMac 24 inch OSX 10.9.4,Nvidia GeForce GT750M 1 GB, 3.1 Ghz i7 Processor 1 TB Fusion Drive, 16 gigs of ram & a iMac 27 Inch OSX 10.9.4 Nvidia GeForce GTX780M 4GB, 2.5 Quad-Core i7, 16 gigs of ram 1 TB Fusion Drive, both have the USB Super Drive from Apple connected to them)
Both are running Compressor 4.1.2. I'm trying to make a disk image from a Apple Pro Res 422 HQ Quicktime 29.97 DF (drop frame, NTSC) The file is big since it's HQ so it takes a while to compress. I'm using the Create DVD preset in compressor and choosing " When Done: Create DVD" then below that "Output Device: Hard Drive" Because I want to have a disk image for back up and future burning so I don't have to tie up any systems doing this again.
It get's the the very end where it has that disk burning icon come up on the dock and then a warning comes up saying that there was a "error making the disk" and then that's it. I want to be able to create a disk image. Old compressor (3.what ever) works great, takes a lot longer to compress things but at least I haven't run into this issue with it.
I've had my destination set to the internal drive's, external drives .... you name it I've tried to save it in different places. I've added a background picture, removed it, nothing seems to work ....
Please help and much appreciated if you can help me out here.
Cheers

Can't play Disk Image in DVD Player

I saved my iDVD project to disk image so I could view the video on my Mac Pro prior to burning the project.
When I double click the saved disk image icon, the archived file that I made earlier populates on the screen instead of the DVD player opening. That's strange?
I see an Audio_TS file, Video_TS file, and a DVD-ROM contents files instead of the DVD player. Why isn't the DVD player playing the disk image that I saved?
I also tried the process in reverse. Trying to open the saved disk image from the DVD Player and the saved disk image is all greyed out not allowing access to view the video.
Thanks in advance for any assistance.

All I want to do is just play the disk image.
Read through the following for help.
http://docs.info.apple.com/article.html?path=iDVD/6.0/en/18.html
http://www.kenstone.net/fcphomepage/image_to_diskstone.html
Once the disc image is created, double-click the .img and burn the virtual disc that should appear on your desktop, using Toast to burn the DVD. Disk Utility to burn the .img file. Usually, you can select a burning speed in Disk Utility.
There are variations to this process based on which OS X you are using...
Open Disk Utility (in Utilities folder in Applications folder), click on the virtual disc (maybe the .img) in the left-hand window. Click the Burn icon. A new window should drop down and your SuperDrive tray will open after clicking the Burn icon. Insert a recordable DVD. (Verbatim DVD-R preferred by me.) Click the Close button. Wait. Select a burn speed. If you hold your mouse cursor over the pop-up it says: "Select a slower speed to work around burn failures," so select 4x or slower for best results. Then click the Burn button.
-->If the virtual disk selection won't allow you to click the Burn icon, use the .img file instead. This may have changed in 10.3.9 and did change in Tiger.
Also, you can use DVD Player to play the virtual disk to check your iDVD project before burning to DVD. Launch DVD Player. File/Open VIDEO_TS (Open DVD Media... in Player 4.6). Find the VIDEO_TS folder and open that. (The audio folder is for DVD-Audio disks.)

Disk Utility 'Disk Image from Folder' looses file create date?

Hi,
I have been working on creating backups that maintain the files' create dates. I have found the following anomoly using Disk Utility.
If I create a Disk Image From Folder, the create dates of all files are changed to be the same as the last modify dates. Not what I want.
If I creat a Blank Disk Image, and then using Finder to copy the files to the Disk Image, the create dates remain unchanged.
I can then burn the backup CD's with the Disk Image and the files' create dates are maintained. So, future restore from the backup CD will contain the original files' create dates.
Does anyone know if Disk Utility's Create Disk Image from Folder is supposed to loose the files' create dates? What other file attributes are being lost? Mac OS X maintains all of these attributes, and create dates via Finder copies, I would expect the Disk Utility Create Disk Image from Folder to do the same.
Bob Horton

To follow up on this post, I know at least part of the answer. The difference between the two becomes clearer if you read the documentation (man pages) for hdiutil and asr. Image 1 will be created in file mode, whereas image 2 will be in block mode, ie bypassing the file system. Image 1 will consist of a series of files, whereas image 2 will contain a series of blocks, mirroring the original layout of the hard disk.
Technically the latter should be faster to restore (in block mode), although Apple recommend the first procedure (see man page for hdiutil). I haven't seen any evidence that images created in block mode can be mounted or restored, although you might be able to burn such images to a optical disks if applicable.
As I've pointed out in another thread (http://discussions.apple.com/thread.jspa?threadID=1508199&tstart=0) I believe that this functionality should not be offered in disk utility, and I consider it a serious bug.

Can't eject disk image from Finder in Mountain Lion

I just got a new MacBook pro. I'm running Mountain Lion (10.8.2). Any time I try to unmount an external hard drive or eject a disk image from the Finder, nothing happens (either clicking the contextual eject icon or right-clicking). The items in question are not in use when I try to eject them. I'm only able to do so with Disk Utility. Any ideas? I've repaired disk permissions but the problem persists.

I am having similar issues with my user account. It also is the same in Yosemite.
Disc images, external hard drives etc dragged to trash (get eject icon) are simply ignored.
Pressing Eject button in side bar of Finder are ignored.
It seems to be a permission/account issue as:
- using computer under a different account doesnt have this problem
- transferring account over to another mac continues the problem on the new computer.
Log file seems not to have any errors.

Can I import images from DVD to my HDD through bridge (I have Win 7

Hi,
I'm using Win 7 (and also have Bridge on Mac OS X). I'd like to import images from DVD to my HDD through Adobe Bridge. But I can't find the option to import from DVD in Bridge (either in Win 7 or Mac). My DVD drive on my Win machine is external while I have the regular internal DVD drive on my Macbook Pro. I'm trying to import images from DVD to HDD through Bridge. Go through the first round of select/reject through Bridge and then take them to LR for further edits.
I currently copy them from DVD drive to a USB pen drive. And then using the Bridge import dialog (when I plug in the USB again) copy them to my HDD. I do this becuase I also need to batch rename my files, add metadata and keywords during import. The simple copy/move function won't allow these additions and so I have to resort to this workaround of DVD to USB to HDD (thru Bridge). If I can import directly from DVD through bridge, it'll save me quite some time.
Look forward to assistance pls.
Thx,
Chinmoy

I feel a bit silly now. For 2 days I struggled and then posted my Q.
After posting the Q, I figured it out in about 15 minutes.
Insert DVD.
Open Br
Navigate to DVD
Select all images
Right Click - Batch Rename
Choose Destination Path and New file name.
And go!
If you've had the same problem I did, hope this helps.

Why suddenly unable to create a disk image from a CD?

I successfully created a disk image from a CD only 5 days ago. Now when I try to create a disk image from a CD (with Disk Utility) the Superdrive rumbles along for sveral minutes, while the progress bar indicates that it has reached the end of its progress.
Only after all that does a dialog box indicate:
"Unable to create "___.dmg"-Invalid Argument. "
I haven't added software but did upgrade to iTunes 6. Doubtful that could affect my abilty to create a disk image.
Would someone kindly shed some light on why this may be happening?
Steve

Is it strange that this problem seems CD-specific?
Some CDs are copy-protected and some CDs are not copy-protected; so, no, it's not strange at all that you should be able to copy some CDs and not be able to copy others.

"Disk Image from Folder" from iPod

Using Disk Utility, I have tried to create a disk image of my iPod using the "Disk Image from Folder" option.
These are the settings I am using:
Location of Image: Desktop
Format: read/write
It asks for my password, and then it briefly is in the "Initializing..." phase (less than a second), and then it gives me the error 'Unable to create "MATTSH_IPOD" - internal error.'
What should I do? I tried creating an image from another folder, it works fine.
I can't create an image by device, because I won't have enough free space...
Keep in mind I am running a new MacBook Pro (yay). Also note that the iPod is formatted in FAT32.
Any ideas??
Thanks in advanced for any help.

Hi Matthew,
I don't own an iPod, but here's what I'd try:
Quit Disk Utility.
First, download and install TinkerTool.
Then in TinkerTool's Applications section, choose "Enable extended options when converting disk images".
I don't know if you need to logout/login at this point.
Now open Disk Utility and try the "iPod image" format.
Let us know if it works for you.

Unable to create Disc Image from DVD

I get the following error when trying to make a copy of a family wedding DVD. I'm using Disc Utility and creating the image as a DVD/CD master (.cdr) file. It gets to about 3/4 of the way and then gives the following error.
The internal drive is a PIONEER DVD-RW DVR-K05

I do not know what that error means. However, if you open up the Disk Utility & go into it's Help Menu & in the search field type duplicating a CD or DVD. There you will find detailed instructions on how to create a disc image from a DVD.
Good possibility your answer may be found there and/or there may have been something you missed in creating a disc image.
Good luck.

System Image Utility 10.6.3 - fails when creating NetBoot image from DVD

System Image Utility 10.6.3, trying to create a NetBoot image from a bundled installer disc that came with a 27" Late 2009 iMac (iMac11,1). Image creation fails consistently, since the image that System Image Utility creates is only 901M.
Anyone see this before?

Hi Don, here's my guess...
The 901 number is additional space added in the scripts. This indicates that the source image size was 0.
Since you are making a NetBoot from Install media, under the covers the installer process is being run to create a NetBoot volume. The media shipped with the 27" iMac is most likely CPU specific and thus the installation fails because you are trying to create the image (i.e. install the system) on an unsupported CPU.
In order to produce a NetBoot from the install media, you'll have to create it on the 27" iMac.
Hi Brian,
Thanks for the response. This makes perfect sense. I'll give this a try and shout back!

Anyone know Disk Utility, Ignore Ownership, and disk image DL DVD issues?

I am currently having issues with backup DVD's I burned using Disk Utility. I can put the dual layer DVD's in and the system reads them. When I try to pull a file off the Dual Layer DVD a circle with an X appears notifying me that I cannot copy the files to my desk top.
When I check the DVD's permissions it reads Admin (me) read and write with the ignore ownership checkbox checked...which means I should be able to pull files off the DVD. The only way I can currently get information off the DVD is to duplicate the entire disk to a new folder by selecting the DVD while holding down the Cntrl key and selecting duplicate. I have had other issues with DVD's and disk images in Leopard....including having to eject either through disk utility or by selecting the image with the Cntrl key held down. Finder eject, keyboard eject, and the menu eject selections suddenly report that the disk is in use.
The DVD's were burned by creating a dual layer dvd image through disk utility with the read/write option checked.
After duplicating 2-3 disks, the system itself is unable to mount any more disks from the series of backups. When I look at disk utility it reads that the disk is not mountable. I have to restart my computer so the system can continue to read the backups.
My Itunes disk backups are marked the same way (ignore ownership) with admin read/write privlages....I have no problem pulling files off these disks.
I have tried both logging in as root and booting from an external drive...same problem. Is this some nasty Disk Utility bug? Is anyone else having bizarre permission related issues with Disk Utility and Disk Images.

When you create the image in Disk Utility, did you
change the 'Partitions' setting?
If you leave it to read 'CD/DVD', it will create a ISO9660/UDF image.
To be able to maintain permission and extended file attributes, you
need to select 'GUID Partition Map'.
I assume you used iTunes to create your music backup?
It seems it creates the correct image type for you.
Before sending this message, I actually created a single layer image,
copied some files to it and gave additional permissions to other users on my system.
Afterwards I copied the files to my Desktop, verifying that the attributes are still intact.
Best regards
(It took quite a while to burn this 4x DVD-RW Anyways, I hope I could help)

How do I compress a disk image (or DVD)

I have a DVD that's 7.6GB and I want to compress it and save it on my hard drive. It's a concert DVD (copyright protected I'm sure) so I want fairly simple access to it after compression. I made a disk image of the DVD and then saved the disc image to the desktop using Disc Utility. A disc image file that ends with ".CDR" is created and saved on the desktop. I have no problem opening the resulting file (.CDR disc image) and getting it to play in the DVD player or anything like that, however it's still a 7.6 GB file. Is there a way to compress the disc image? I read a post about dragging/dropping the disc image from the desktop into terminal (which I've never even opened before today) and then terminal would automatically compress the disc image. Is this correct? If it is, where is the resulting file (the compressed disc image) then stored? Is this even the easiest way to compress a DVD? Do I even need to make a disc image first, or is there software that will automatically compress the DVD for me and allow my DVD player to open it? It seems like there ought to be an easier way. What am I missing here? I'm not going to save a DVD (or disc image for that matter) that takes up that much space (7.6GB) on my hard drive. Thanks for any help. Michael

Copy protected DVD's (if that is what this one is) make copying difficult by intent. You can try MactheRipper to "rip" it to unprotected form, but please read & heed the caution about the legality of doing so at the developer's web site.
This app may or may not remove any copy protection, since DVD makers understandably sometimes modify their schemes in an attempt to defeat apps like this one. You may also need to make decisions during the ripping process that may affect the way the content plays. IOW, this isn't a 'one-button & your done' sort of thing.
That said, any unprotected DVD can be compressed in various ways by various apps, but you should be aware that compression affects playback quality. Different apps give you greater or lesser control over this & it may well be that compressing the content to a size acceptable to you results in quality that isn't acceptable.
The commercial apps Popcorn & Toast Titanium 7 are probably the easiest to use for this, but that is because they mainly are intended to compress 'jumbo' DVD's down to a size that fits onto regular ones, about 4.7 GB. For better control of compression vs. quality, you will probably have to use more 'geeky' stuff and/or use MactheRipper to discard whatever is least important to you.
If all this sounds like too much trouble, consider investing in more drive space for your .cdr files or just buying extra copies of the DVD's you need to archive.

Disk images from CDs are always damaged

I'm not sure when this first cropped up, but it's been happening for a while now. Every disk image I make from a CD, seemingly no matter what disk it is, gets flagged as possibly being damaged from the very first time I attempt to mount it. I've tried several different disk types, all result in the exact same thing.
The images appear to be effectively identical, with files and even icon-location exactly the same, but they still flag the error. The only thing that I think changed when it started is that I have an old copy of Toast (I think 7), and whenever I make a disk image there's a line saying that it's reading Toast 4.1 HFS Optimizer. Could that be related, and if so, how can I get rid of it?

Klaus1 wrote:
Most of us make CDs and DVDs from disk images.
Yeah, true. But where do you think those disk images come from in the first place?
As to the other two, I'm trying to make duplicates of many kinds of CDs. Games, videos, school (class-related) disks, etc, because carting around a dozen disks to make it through my day is just asking for some of them to snap or get huge scratches.
I'm attempting to make disk images through the Disk Utility.app, and that's been the source of the problems.

Encoding process isn't working properly while making the disk image (or DVD)in my iDVD program. Is there a remedy for this?

I've used Old Toad's suggestion and made a disk image first because the DVDs I've tried to produce show a few pictures in playback and then go white. The slideshow works fine in the iDVD program, and in the initial rendering stage all seems o.k. until the encoding step. Then, it processes 4 or 5 pictures, then goes blank but the music continues to be processed. Is there a remedy for this (I know Apple has ditched the program and the optical drives.) I deleted the project and tried making it over from scratch, but no luck.

I am simply lookig for some help not an argument. I am not an RF specialist however have setup a few wireless networks in my tenure at Wynn Resorts. I fully agree that wireless networking is an art and a science however the powers that be in Network Land have toughted wireless networking is the easiest and quickest way to get two computers to talk with one another. As I previously said I have already turned one (1) MBP in for this problem and Apple decided to replace it because they could not fix the problem with my particular MBP. This MBP was running Leopard when the problems started
I am having a hard time believeing that there are several other devicces in my home that depend on a wireless network to operate and my MBP is the only one having an issue. I took this a step further and decided to see what would happen if I tried to connect wirelessly via Fusion. In Windows 7 I am able to print and scan to my hearts content without any issues. I am able to browse the internet as much as I want. I close Fusion and try to connect to my printer via wireless and nothing.
In order to get Apple to help do I need to get a Network Analyzer and capture packets when I have these problems? Out of the 1000 + posts is there a consolidation of which answer is the best? BTW I am accessing the internet via a wireless connection using Fusion and Windows 7.
In response to Linc's comments, I will look at the router specifications however I did not qualify that these devices are not using the wireless connection at the same time. Right now I would guess there are maybe two (2) or three (3) at the most that are actively transmitting / receiving information. -- Thanks
