Drutil

Dear Wise & Powerfule Masters of OS X,
I would like to use drutil to burn automatic backups. I have a script launched by crontab that looks like this:
<begin shell script>
cd #kks050305
cd Desktop #kks050302
mv 'Untitled DVD.fpbf' backup.fpbf #kks050302
cd #kks050302
nice tar --exclude=Deskto/backup.fpbf/ks.tar.Z -cvf - *|
compress>Desktop/backup.fpbf/ks.tar.Z
drutil burn
<end shell script>
As you may have noticed, the drutil syntax is wrong. What would be the correct syntax to burn the DVD?
I am open to any other improvements that you may suggest.
Your humble geek,
Kurt

Hi Kurt,
   You can't burn anything without a filesystem being created at some point that is appropriate for CDs. Thus, you can certainly provide a path to a .dmg or .iso file to "drutil burn". Of course you are also correct that drutil is sophisticated enough to actually create that filesystem for you behind the scenes. This is from the drutil man page:Burns a valid directory or image file to disc. The default is to burn the specified directory to a new filesystem. ... If a file is specified (valid image files only: .dmg, .iso, .cue/bin, and .toc) the contents of the image file are burned.In other words, drutil uses the distinction between a file argument and a directory argument to decide whether it needs to create the image filesystem. Therefore, it should work to simply put the tarball in its own directory and use the path to that directory in your drutil command.

Drutil problems

HI all, I'd like to solve some problems which may arise when i try to burn an audio cd
1) if cd is not inserted
2) if there is no audio file to be burnt
now if one of the two happen drutil just hangs and becomes unresposive.
So all i want to do is to killall drutil if one of the two happen.
Is that possible?
Thanks!
PS this is my rude try, which is not working (otherwise i would not be here ;-)
try
do shell script "drutil burn -audio -noappendable -drive 1 /myaudiofolder/ 2>&1 &"
on error
do shell script "killall drutil"
end try

I think you will need to check that the two conditions (disk inserted and valid file to burn) are true before calling drutil.
That is first make sure the filename you are passing to drutil exists and thne make sure there is a disk inserted in the DVD drive. Finder should be able to do both of there things for you. Once you know both conditions are true you can call drutil.

Problem specifying burn speed with drutil

Hello,
In another thread, I was looking for help getting hdiutil to write to an external drive. This didn't pan out so as suggested, I'm looking at drutil which supports multiple methods for specifying which drive to use. The only remaining problem is that I can't figure out how to specify the burn speed. I have a feeling I'm overlooking something obvious.
Any help would be great.
Cole

I tried drutil based on the syntax you used to rule out any errors I may have made earlier. If I include -speed, it just prints usage. If I remove -speed it works, but sounds like jet engine starting up:
<pre style="padding-left: .75ex; padding-top: .25em; padding-bottom: .25em; margin-top: .5em; margin-bottom: .5em; margin-left: 1ex; max-width: 80ex; overflow: auto;font-size:small; font-family: Monaco, 'Courier New', Courier, monospace; color: #222; background: #ddd; font-size: 9px; line-height: normal";>sw_vers

2009 MBP cd slot won't open - drutil not working either

Hey all,
My wife's 15inch Macbook Pro mid 2009 running Lion's superdrive slot stopped accepting discs. I was able to fix it a few weeks ago with Terminal drutil open or drutil eject but now nothing will work.
There is nothing IN the drive right now, but can't get anything in.
Short of taking it in for repair/replace... is there anything else I should try? I can't find any type of paperclip hole.
Thoughts?
Thanks,
CaptM

Sounds as if the SuperDrive has just given up the ghost.
You should take the machine into your local Apple Store and have them give you an estimate to fix the drive. If it means replacing the drive, that's something you can do yourself (and it will be quite cheaper than the Apple estimate).
If the drive does need replacing, shop at OWC for the correct drive for your model. They will also have installation videos.
Good luck,
Clinton

My iMac will not boot up from the Leopard upgrade disk nor will it eject it.

My iMac is very slow and sluggish. Followed online instructions to use the Disk Utility to run repair. After doing so it told to reboot my system from the install disk and then run the Disk Uitility to run repair from it. I put in my Leopard upgrade disk and tried to reboot. I get the chime and the Apple logo and hear the disk trying to be read, but after about 5 minutes my iMac shuts completely off. I have tried to eject the disk using all the methods found in the community and nothing works. I want to try my orignal Mac OS X install disk to see if that works. My computer is about a 2007 model. It worked great until just a couple days ago. Frankly I can't afford to take it in so I will have to figure this out on my own with your help. :-(

I cannot open terminal. When booting I get the gray screen with the Apple logo and the twirling comb goes for a while and shut the computer completely off.
I got into the single-mode user and learned the following: disk1s3: I/O error. SAM Multimedia: Read & Write failed, SENSE_KEY = 0x03, ASC = 0x02m ASCQ = 0x00.
Singleuser boot -- fsck not done
Root device is mounted read-only.
If you want to make modifcations to files: /sbin/fsck -fy
/sbin/mount -uw /
I typed in the drutil eject and got:
SAM Multimedia: Read & Write failed, SENSE_KEY = 0x03, ASC = 0x02m ASCQ = 0x00.
Library not loaded. Reason: not suiteable image found.
It did find:
/system/library/rivateframeworks/installserver.framwork/versions/a/installserver : unknown file type, firfst eight bytes: 0xCA 0xfe 0xba 0xbe 0x00 0x00 0x00 0x04 Trace/BPT trap.
I have tried holding the left mouse key, the eject key and nothing happens. To bad I can't pull the
thing out with tweezers.
So where do I go from here?

HT3413 How can I get composite video out of the 13" early/mid 2009 MacBook?

OK, the Mini-DVI - DVI Adapter "works with" the 13-inch, Early and Mid 2009 MacBooks.
But can it combine with a DVI to S-video and composite adapter so I can play video from my MacBook (one of the above) to my TV (composite input)?
It is stated in many places that the Mini-DVI to S-video and composite adapter doesn't "work with" these models, and I've proven that's the case.
But I can't find anywhere that explains why, or says more than "works with," or just tells me how I could get any external video from my MacBook other than VGA which is useless to me as far as I can tell.
Thanks for any help!

Five ways to eject a stuck CD or DVD from the optical drive
Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this: Open the Terminal application in your Utilities folder. At the prompt enter or paste the following:
/usr/bin/drutil eject
If this fails then try this:
Boot the computer into Single-user Mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.

Can't eject disc & it doesn't even show up on system!

I installed Parallels 5.0 from the installation disc, which seems to be installed just fine, but now I can't eject the disc and it doesn't even show up under devices. I tried all these things below except the last one (because I couldnt get my mac to start like it describes). What now? I just bought this Macbook Pro new a week ago - soooo annoying!
Ejecting a CD or DVD when all else fails
If you've tried all the usual methods of ejecting a CD or DVD from your computer's optical drive, there are some other methods you can try.
First, quit all applications that are using files on the disc. Then try one of these alternate methods:
Open Disk Utility (in the Utilities folder of your Applications folder), select the disc, and choose File > Eject.
Choose Apple menu > Restart and hold down the mouse or trackpad button until the disc ejects.
If your drive has an emergency eject hole, put the computer to sleep and insert a large, straightened paper clip in the small emergency eject hole of the drive (the location varies, depending on the drive). Push firmly until the disc ejects.
If all other methods fail, you can try to eject the disk using the firmware. (This may not work on all computers. For example, it does not work on Intel-based computers.) The steps below describe how to start up and briefly use the computer with only the firmware loaded, not the standard Mac OS X interface.
To eject a disc using firmware:
Restart the computer.
When you hear the startup sound, press and hold the Command-Option-O-F keys. (The Command key has an Apple on it.)
Release the keys when you see a white welcome screen.
At the prompt, type:
eject cd
Press Return, then wait a few seconds. The disc drive should eject the disc, and "ok" appears on the screen when the action is complete.
Type:
mac-boot
Press Return.
Your computer starts up normally and you see the familiar Mac OS X desktop.

Open the Terminal application in your Utilities folder. At the prompt enter or paste the following:
/usr/bin/drutil eject.
If this fails then try this:
Boot the computer into single-user mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
I suggest that to start with you shutdown the computer. If you are unable to remove the DVD then it's possible there's a problem with your optical drive. Take the computer in for service.

Opening/closing cd tray...

So I guess “drutil tray open/close” only works on G4s & G5s.
I had some fun with it at work today but when I got home
realized it doesn't work for my B&W G3.
Is there another command that'll open/close the tray or
am I outta luck on my G3?
Thanks in advance!
Mike

Thanks folks - but none of that worked.
I don't have a cd stuck in there or anything.
I can open it via terminal with a cd in the tray but
can't open/close an empty tray.
I'm just trying to do this in terminal for fun.
F12 does work but I'm trying to figure out
the unix command to mess with the wife's head
while I'm at work! hehe
Thanks again!

I've read somewhere that the G4 & G5 have a “powered”
cd drive??? - wouldn't all of them be powered???

You might need to use the command, disktool, instead.

My computer is showing a File Folder with a ? Symbol! PLEASE HELP!!!

My computer froze while I was doing homework so I tried to restart it and when I did, It doesn't show the apple logo but rather a File Folder with a ? Symbol! I tried reselecting the hard drive but it didn't show! I looked up how to fix this and tried it all and non of it helped me:/ I CANNOT lose my information on my harddrive cause I have very IMPORTANT work on there! I have mac OS X Lion! So I don't have a start up disk for that and the one i have is stuck in my computer right now! Apple won't help me and I need my computer soon! PLEASE HELP!!!

Reinstalling Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the 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.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main 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.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

How can I remove a CD in Combo Drive of Mac Mini?

This is a Mac Mini operating on OS 10.58. I have a CD in the combo drive, and it apparently has something recorded on it. I think this CD had started to be burned and I stopped it. The computer indicates that this CD is not blank. The result is that it will not eject, even after several attempts using the small eject arrow at the top of the desktop, the use of apple-E, and after repeated efforts with a complete shutdown -- still the disk is stuck in the drive. I suspect that it's in a loop situation, where it tries to run the CD with not effect, but it also cannot eject it.
I notice a small black square, appearing to be black plastic, at the far right end of the CD/DVD player slot at the top of the Mac Mini. In the old days there was such a hole into which one could stick a straight wire, like a heavy duty straightened paper clip, and it would physically eject a stuck disk. Is there such a thing on this Mac Mini?
Any good suggestions, please!? Thanks!!

Can't eject disk!

Hullo all, have had a frustrating time in trying to eject an install CD from my wife's MBP.
Set out below are some suggestions obtained from the web......nothing will eject the disk.
I am trying to re-instal OSX Snow Leopard then move to Lion. Have sucessfully deleted the hard drive using Disk Utility from the instal disk, but now I find I am in a loop!! Try as I might, the disk is firmly implanted in the drive, obviously it does not show on the desk top, as there is nothing behind it!! ie all HD deleted.
Any way out? Of course there musty be, but I am tired and have had an agruement with my wife over this issue!!!
Frustrations!!
Using Terminal was of no help!!
Ron
The suggestions were.....
From time-to-time, removable media (including CDs, DVDs and others) can refuse to eject via the normal Mac OS X methods -- pressing the keyboard eject key; using the Command-E keyboard combination; selecting the item in the Finder and clicking the Eject button next to its name; dragging the item to the trash; or pressing the F12 key.
A number of methods can be applied to help coax media out of an optical drive in such a situation. Before applying these methods, however, note that busy disks (either startup disks or disks with an open file) should not be ejected and will not using any of the aforementioned standard processes. As such, be patient with a disk that will not eject immediately. Sometimes a disk continues to be identified as busy for several seconds after any contained files are not in use, and waiting a few moments then re-attempting the ejection is successful.
Use Disk Utility to eject The first and simplest method, if you only want to unmount a single volume on the disk, is to use Disk Utility, located in Applications/Utilities. In Disk Utility, simply select the volume you want to unmount and click Eject.
Hold Down the mouse button at startup In some cases holding down a connected mouse button at startup will cause a misbehaving optical drive to eject its media.
Unfortunately, this method will not work if you are using a Bluetooth keyboard.
Also, for Xserve users, make sure that the machine is unlocked (using the included allen wrench) before holding down the mouse key during startup.
Boot into Open Firmware and eject If you have a Mac that will not startup properly and has a stuck disc, try booting into Open Firmware by holding down Command, Option, O key and F key during startup. After booting into Open Firmware, type the command eject-cd.
Using the Terminal There are two commands that can be used in the Terminal (located in Applications/Utilities) which can be used to force disk ejection:
The first command to try is drutil tray eject. Simply type in this command and press return.
The other method takes a little more work but can work in instances where the first method fails.
Type the command drutil list into the Terminal and press return . This will provide a list of all currently connected removable devices. [ScreenShot 1-DiskEject] -- connect FireWire/USB drives for this
Use the command drutil tray eject 1
In the above command, the number "1" should be replaced with whatever drive number you obtained in the first step.

You may have tried all the suggestions mentioned in this article - Apple Portables: Troubleshooting the slot load optical disc drive
You will probably end up taking the computer to an Apple store or an AASP. If you have Apple Care, call them and let them deal with it.

When I turn my MBP on, it makes a whirring and grinding sound for a few seconds (5 secs?) and then boots up normally. The sound appears to come from the right side, perhaps near/under the button.

The MBP makes no noise after this. I can't recall ever dropping it.
I purchased it in Jan 2011 (so I'm guessing it's a 2010 model? No idea. Has black keys & new, slim charger!)
Happens when I've turned it off and on & when I restart.
What do you think the problem is most likely to be?
I've had it over a year now so my Apple warranty is already up. I got it from John Lewis though, who give you 2 years warranty.
Both John Lewis & Apple stores are 1-2 hours away from where I live now.
Should I -
a) visit the Genius bar and hope they can fix it there and then? What does Genius tend to cost & can it be quick?
b) take back to John Lewis (and I guess they'll fix it for free under warranty but take a zillion years!)
c) find a repair shop where I live, who will look at it quicker but may also cost and arm and a leg?
d) any other suggetions? Maybe never turn the laptop off again ;-)
Thanks in advance for any help/advice/tips/solutions!
Carly.

OK - more details/info now.
When I use terminal and type this:
drutil eject
I believe the DVD drives makes the odd noise I heard when I booted the laptop up.
Any thoughts?
I'm guessing that means my fan/hardrive are actually OK then, and it's probably the mechanism in the DVD drive that is causing problems?
I'm almost certain there's no DVD stuck in there?

Unable to dismount Hybrid Karaoke CDG disk formats in Mac OS 10.5.6

Hi Everyone,
Ran into a problem today, when I put in a karaoke CDG disks from a company called "All Star Karaoke", I see an Audio CD mounted as well as a "Untitled" cd mounted. I cannot unmount these CDs unless I reboot and hold down the touch pad button. I have tried using DiskUtility to unmount, to no avail.
There is even a discussion of this issue in the kjams.com forum here:
http://karaoke.kjams.com/forum/viewtopic.php?f=1&t=336&p=1977
Does anyone have a solution or work around for this Mac OSX bug, besides using a sharpie marker to mark out the outer sectors?
