Problem burning a .dmg file

I have a G4 powerbook. I have burned dvd's before but I am know experiencing a problem. I created a home video that I then burned to dvd using imovie. I have done this a number of times before. After i have the finished product I then copy it and save it as a .dmg file. I was always able to make copies using the .dmg file, but when I burned it this time it burns it as a data file and not as a watchable dvd. Any ideas what I am doing wrong? Thanks

When it start working it should show a moving progress bar at the top of its window. If it just says "Working", something is wrong. Often this is due to a bad disk name. The name must be upper case only, with no punctuation (other than underscore _) or spaces. Only digits, _, or uppercase letters. Also the name can't be too long. Probably 31 characters maximum. If it still fails, it could be a problem with the files in your VIDEO_TS folder. If the VIDEO_TS file names look OK (compare them with a working DVD) you may need to use myDVDEdit

If it is a simple error, it will detect it and let you save a corrected version.

Burn a .dmg file on a pc, have it bootable on my g3

I recently purchased OS X Tiger. I backed up the CDs on my PC, now is there anyway i can burn the .dmg files to a disk and make them bootable on my Mac G3?
Thanks
Jeff

I guess that means they are not going to work as copies of the installer CDs.
Do you have the facility to make the copies on a Mac? That would be your best bet. You can make copies on a Mac as follows:
Duplicate a CD or DVD
1. Insert the DVD/CD;
2. Open Disk Utility, and select the DVD/CD from the left side list (select the DVD/CD icon on top);
3. from the DU File menu select New | Disk Image from Disk 1;
4. Choose to format the disk image as DVD/CD Master, name the disk image and click Save;
5. When the .cdr file is finished select it with mouse and press COMMAND-I to open the Get Info and check the box to lock the file;
6. Choose the .cdr file from the left side list, click Burn, and insert a new, blank DVD or CD.

Disk Utility burn error with dmg file

I'm using a Pioneer DVR 106D to burn a dmg file on to a blank DVD. I've done it many times before with the disk utility.
But now I'm getting this message when I try to burn the dmg or make a new image off the old DVD master:
"Device drained its buffer without burn underrun protection"
Can anyone please tell me how I can fix this problem?
Thanks
OS 10.3.9

I have encountered the same problem. I have a Mac Book Pro from 2007, and it has gone through 3 DVD writers so far, all of which have ruined DVD+R DL disks. I have occasionally been able to burn one, but usually during verify, I get this error message:
Communication to the disk drive failed: 0x8002022
And disk utility fails with a "Invalid B-tree node size" error
Oddly, when I try to burn a disk near capacity (6.5Gb or more) it is more likely to fail than if I burn a smaller disk.
I've been using Memorex DVD+R DL disks, but I have used other brands in the past but they have failed, too. Out of about 50 disks so far, I have had success with about 5.

FYI OS 10.4.9 can't read dmg files on an external hard drive

After I upgraded from 10.4.8 to 10.4.9, my G5 iMac would no longer read digital image files (dmg) stored earlier on my external hard drive. I tried various fixes from the Discussions topics. But the files would not read, giving me a: "Finder cannot complete the operation "file name XXX" ..... could not be read or written (Error code -36)".
I don't have a "fix" but I do have an inelegant solution to retrieving the files.
I plugged the hard drive into a windows XP computer (laptop) and transfered the files to a USB media reader (SD/memory stick type). The windows machine had no problem retrieving the dmg files. I then plugged the memory stick into my iMac and the iMac read the dmg files just fine.
The files are not corrupted and the disk drive obviously works, so I wonder what was different in 10.4.9 that made it quit reading the external hard drive, while still reading memory stick devices? Maybe 10.4.10 will resolve the issue.

Have u tried the usual? Safe boot. Delete finder plist files? etc. And the drives are formatted for mac yes?

.DMG files on a PC

Is there anyway to burn a .dmg file on a CD so that a PC can read it. I just tried it and it didn't work. The PC couldn't read the CD.

Hi, Abe.
Is it that the PC could not read the CD or the disk image?
CDs burned in Finder are compatible with Macs or PCs running Windows. See "Mac OS X 10.4: Creating a CD Formatted for MS-DOS (Windows)."
However, while "Disk Utility 10.5 Help: Formatting a disk for Windows computers" states:"When you create a disk image you can erase it and change its volume format so that other computers, such as MS-DOS for Windows computers or UNIX file system computers, can read it."Under Tiger, I've not found a way using Disk Utility to create or change a disk image with a Mac volume format to one formatted with the MS-DOS file system. Hence, a disk image created on a Mac using Disk Utility won't be readable on a PC unless the PC is running an application like Mediafour's MacDrive for Windows.
With Tiger, disk images now always use the Mac OS Extended file system. Under Panther, one could create disk images using the MS-DOS and UNIX UFS file systems, but that's been removed from Disk Utility under Tiger.
One can use the hdiutil command in Terminal to create a new, blank, Read/Write disk image, or an image from a folder, that uses the MS-DOS file system by including the
-fs MS-DOS
flag in the command.
For example, the following Terminal command:
hdiutil create -srcfolder ~/Desktop/Test -fs MS-DOS -volname DOSTest ~/Desktop/DOSTest.dmg
created a disk image:
• from the folder Test on my desktop (-srcfolder ~/Desktop/Test)
• in MS-DOS format (-fs MS-DOS)
• with volume name of DOSTest (-volname DOSTest) so that when it is mounted it shows as volume "DOSTest" in Finder.
• with the disk image saved as DOSTest.dmg on my desktop (the last parameter, ~/Desktop/DOSTest.dmg).
The command produced some error messages, i.e. two instances of
mount_msdos: /dev/disk3: Resource busy
/sbin/mount failed with error 18176
during the creation process which I have yet to explore, but it turns out the resulting disk image appears fine and mounts on my Mac. It mounts as volume "DOSTEST" (vs. volume name "DOSTest" but -volname may be case insensitive).
Disk Utility shows the mounted volume as having:
Format: MS-DOS File System (FAT-16).
One could then try burning that disk image to CD and seeing how a PC handles it. I don't have a PC running Windows handy at the moment, otherwise I'd try that.
Hope that helps.
Good luck!

My mac is a Mid 2012, 13'' MacBook Pro

I've been instructed to download an .exe file of Windows XP Service Pack 3 in order to update a corrupted and restored Windows XP in Parallels on Bootcamp.
I downloaded to my MacBook and tried putting the .exe file in a folder and burning it to CD but received this message
"The disc could not be verified and might be unreliable. Try again using a new blank disc. (Error code 0x80020063)"
Is there a way to burn just the .exe file alone directly from its location in my Downloads file to the CD?

I need to burn a .dmg to an external disk

Hi i need help to "burn" a .dmg file into an external disk partition so every time I conect it it open as if conect a disk with a dmg image burnt to it
Chucleskill 

Use Disk Utility to restore the dmg file to the partition. The partition already opens as a disk. If this isn't what you're wanting, be more explicit, especially what's on the dmg file.

I want to "burn" a .dmg (windows 7 file) to a bootable usb stick

I have a late 2008 Macbook Pro and the superdrive doesn't read or write any disks (a common problem with this type of syperdrive)
I want to install the dvd with Windows 7 on my Mac and of course i can't because of my superdrive problem.
I have converted the dvd to a .dmg file so that I can make a bootable usb stick.
But I can't "burn" the .dmg image to a usb. I've tried many ways to copy it but unsuccessful.
Can someone please help me?

Unable to burn DMG files to CDs on external USB2 disc burners?

Hello.
I am having difficulties burning 88.x MB DMG files to CDs (new CD-Rs and an old CD-RW) onto two different external USB2 disc burner drives (both have power AC connected: HP and LG Super brands). The new Mac Mini (no disc slot drive)'s updated 64-bit Mac OS X 10.7.4's Disk Utilities tries to burn and then fail right away or after a few seconds. The error says "Unable to burn 'whatever.dmg' (The disc drive did not respond properly and can't recover or retry." Nothing interesting in dmesg, but Disk Utility's logs had details: http://pastie.org/private/6tnqcnkwycr2yftp8gkzxw ...
I do see my drives' lights on during the burn. I can quick erase the old CD-RW fine. I can burn 538 MB from an 64-bit Windows 8 on my Acer AM3800 PC with the same discs and external burner drives without any problems. Also, I thought it was my USB cable extension, but it wasn't it. I don't use any USB hubs either. DMG files are fine too. I did notice copying from a CD to Mac Mini's local HDD was slow, but no failures.
What could be the problem? Is USB2 too slow or something? Thank you in advance.

Did you look at...
~/Library/Logs/DiscRecording.log
USB2 is slow, but not that slow, but have you tried reducing the burn speed?

Burn DVD/ dmg/cdr file question

Hi- What happened to the dmg files that used to work on external dvd/tv players?
I'm trying to copy a dvd (home movie/ no copy protection) from someone abroad. The region seems ok, the original plays on my computer, plays on my tv via a jvc dvd player and another phillips dvd player.
I make a copy of the original dvd, via making a disk image; the file format is not dmg but cdr. Burn is ok, will play in the computer, but WILL NOT play on the same tvs with the phillips dvd player, or the jvc dvd player. Any suggestions how I can get this to play via the dvd players? Is it related to now having the cdr files?
In the past I've made lots of home movies and was able to burn them to a dvd and they would play on the same dvd players. I think the file format was a dmg though. ??????

Yes. I see that on the old powerbook G4 and the new imac, the process is a little different, but playing around with this I see that if I burn the cdr image to the dvd it's fine,like as a backup for the disk image, but I assume it's not meant to play in an external dvd player. Is that right? When I burn the contents of the cdr image to a dvd and just get the video__ts folder, then it plays on the computers, and it does play on a newer, cheap phillips dvd player but not on the older jvc dvd player. The original dvd I wanted to copy was from outside the US, so I'm wondering if it's a region problem with the JVC.
Several years ago I did some work with imovie and idvd and burned dvd's and they worked fine in the JVC. The original dvd I was trying to copy today also works fine in the JVC. Just can't figure out what' the problem.

Burning DMG File To DVD

I am trying to burn Adobe CS4 dmg file to DVD as a back up. The size is 6.9GB so I am using a Dual Layered DVD which is at least 8GB. For some reason when I try to burn the dmg to DVD I get a message saying "disk doesn't have enough space. Am I doing something wrong? Here are the steps I took...
1) Inserted blank DVD
2) Added DMG file to Disk Utility
3) Highlighted DMG file within Disk Utility and chose the burn option from the menu
This method has worked previously with a 6GB dmg file of iLife using the same exact blank Dual Layered DVD. Also, FYI I am running 10.5.5 Thanks for any help. It's greatly appreciated.

Are you expanding the DMG (you don't want to)? Incidentally, the iLife copy is different than what you are doing. Are you trying to copy the CS4 disk? If so, DU can make an image for you, of the disk. Make certain you save it as a "master", not "encrypted", or any other choice. Then, as you explain, select it, and hit burn.

Problems with *dmg files

hi...
i can't install programs... i've changed once a *dmg extension... and now i just can't open to install aplications.
can anyone tell me what aplication opens a *dmg file or how i can i do to fix my problem...
thanks

enlarge on what you say about your problem please: are these files actually .DMG Disk image files ? If they are not, then, as our friend says you are doing the wrong thing: what are they? where did they come from ? how big are they ? etc...
OR do you mean you simply changed 'open with' once time with a DMG file.
best

I continue to receive "failed to mount" when trying to install .dmg files or updates. Has anyone found an answer to this problem? I am operating on Mac OS X 10.4.11

Problems with downloading dmg.gz files with Firefox

I've noticed some problems where Firefox has problems trying to download dmg.gz files, and it will spit out a bunch of garbled "code" to the screen instead of downloading the file. I tried the same file, just as a dmg file, and Firefox downloaded it just fine. Any ideas on what is going wrong here? Is this some limitation with Firefox and not understanding dmg.gz files, or is the disk image not being created and compressed properly, or is this a matter on the server that would have to be fixed?
I haven't noticed this problem of trying to download dmg.gz files with other browsers like Safari or OmniWeb.

I don't know where the filename->filetype mapping is in Firefox, but I do know that the popup menu on links includes a "Save link as..." item. So command-click or hold down the mouse button for a while or right-click on one of the links that causes problems and select that item. That will give you a standard "save as" dialog box and you can save the file. This trick works for any link and any filetype.

Problem opening .dmg files?

Hi all,
I've recently been having problems opening .dmg files -- specifically for a recent Adobe update, and the latest VLC update.
Checking with their support, it seems that it's not a problem that others are experiencing.
I get the following message:
I'm on the 2007 27" iMac, with my OS (SL) being up to date.
Any suggestions?
Thx!

Could be either.
Check out your own stuff as far as you can. Your router diagnostics page should be able to tell you what sort of download speed you're getting, or you can use SpeedTest http://speedtest.net/
Check your phone line from the main terminal to the router for loose connections, kinks that may be hiding broken wires and such. Check or replace the line filter that seperates the modem line from the phone.
Then get your ISP to check out their end, and the phone company likewise.
Hope you can find the source.
