Disk Utility won't allow Master Boot Record?

Hello all -
I just purchased a WD MyBook 3TB hard drive for storing our movies on. We had our previous external hard drive (250GB) plugged into our Sony Blu-Ray player and it worked smoothly. But now, I plug in our new hard drive, and the blu-ray player doesn't recognize it.
I tried re-formatting the hard drive as FAT32 (same as the old hard drive), but that didn't work.
The only noticeable thing I see is that the partition map scheme of the WD hard drive is "GUID Partition Table", and the old hard drive's map scheme is "Master Boot Record". I went into Options in the Partition page of Disk Utility to try to change the WD hard drive to Master Boot Record... but it won't let me. It's greyed out. It's there as an option, but apparently not for my hard drive.
What gives? How do I get around this? Thanks in advance for your help!

Alberto you're right, but here's what Lacie answered:

hi, if you already have the disks RAIDed from OSX then you can't re-RAID them in Windows. The only thing you can do is set it to a RAID, volume scheme and file system that both OSes are able to detect.
Otherwise yes, if you haven't already set a RAID mode on another OS then the disks can do RAID 0 and 1 in Windows.

Disk Utility won't allow me to restore from image

I've been keeping pretty good backups for a while now and I have started using SuperDuper to keep whole DMGs as well as using Time Machine. Today I planned on restoring from an image I had made. However, when I go to use the Restore function in Disk Utility, it lets me choose the disk image but will not let me drag the volume on the destination field.
I've been having startup problems all day and I eventually got a 9972 error in Disk Utility.
I'm having trouble finding my install disks and this is my only real option for today. I can't find much about this on Google either.

There's no point in using a disc image for a backup. Better to simply clone to a backup drive then maintain the clone with incremental updates. Use a normal backup utility such as Carbon Copy Cloner or Super Duper.
As for the 9972 error you will find it's a really difficult error to correct. See the following:
How to Deal with a -9972 Error
Contributed by Fumiaki Kawashima
The error message, "Error: The underlying task reported failure on exit (-9972)" is a serious filesystem error in the Mac OS X Core Foundation. The problem can also lead to other critical errors such as "Keys Out of Order," "Invalid node structure" and/or "Invalid sibling link." The causes and scenarios vary. Troubleshooting a solution may depend upon computer configuration and whether the -9972 error is accompanied by other critical errors. This issue can also lead up to a kernel panic. If the error occurs when an external FireWire device is connected, disconnect it until you verify the device's compatibility.
Symptoms:
In most cases, you are unable to restart from Mac OS X.
* A volume is grayed out or not mounted with or without a kernel panic.
* A folder with a flashing question mark may appear.
* A bad partition map may be reported.
* A target disk mode solution may not work.
* Most likely, Disk Utility, Norton Utilities, TechTool and DiskWarrior cannot fix the issues.
* The high level disk format (Standard format) may unable to perform.
* You may unable to re-initialize the hard drive.
* A disk physically malfunctions in the worst case.
Example of an accompanied error message:
DiskWarrior normally fixes 1 to 6, but cannot fix errors 7 to 10 if the symptoms are very bad. There is no definite case.
01. Volume check failed
02. Invalid B-tree Header
03. Invalid map node
04. Invalid extents entry
05. Invalid clump size
06. Incorrect block count file
07. Invalid node structure
08. Overlapped extent allocation
09. Keys Out of Order
10. Invalid sibling link
Related documents:
What to Do When It Finds an Error
Technical overview of disk volume structures
Possible causes:
* Third-party FireWire device or enclosure, or other peripheral devices.
* Third-party mass storage drives or PCI card issues.
* Incompatible third-party kernel extensions.
* Mac OS X installer disc is improperly treated.
Solutions:
If possible and needed, back up data before troubleshooting. Methods (4) and (5) are for Power Mac desktop computers other than G5 models. The best bet is method (4) if you encounter multiple bad errors.
1. Unplug the power cord. Disconnect all third-party hardware except Apple keyboard and mouse before you start.
2. Do NOT re-install any third-party software/hardware until you completely solve the issue(s) and carefully investigate the compatibility with Mac OS X 10.3.x you install.
3. If another critical error "Invalid sibling link" is detected at any phases, disconnect and reconnect all internal power cords and data cables for hard drives and any ATAPI device. To do so, you may need to read the computer's CIP Instructions in advance. Normally, you do not need to remove third-party RAMs.
Method 1:
(1) Start up from Mac OS X 10.3.x Panther Full Install CD or DVD.
(2) Re-initialize and re-partition the hard drive. RECOMMENDATION: Select "Zero all data" option if "Invalid node structure" or "Keys Out of Order" error is detected.
If this method is of avail, go to Method 2 or greater.
Method 2:
(1) Start up in Mac OS 9.2.2 and shut down the computer.
(2) Start up from a copy of a Disk Warrior bootable CD for Mac OS 9.2.2.
(3) Run DW to fix the damage(s).
Method 3:
(1) Unplug the computer.
(2) Find a second ATA drive and jumper it as MASTER. Jumper the hard drive in question as SLAVE. Verify the jumper pin settings.
(3) Install Mac OS 9.2.x system on the MASTER drive, and update it to Mac OS 9.2.2.
(4) Start up from Mac OS 9.2.2. Re-initialize and re-partition the damaged hard drive with Drive Setup using the "Zero all data" option. Unplug the computer and reconfigure the jumper pin setting on the repaired drive for MASTER and the second drive for SLAVE.
(5) Restart from Mac OS X 10.3 Panther full install CD. Re-initialize and re-partition the repaired drive to install Mac OS X 10.3. Update to Mac OS X 10.3.7 via Software Update. Repair the disk permissions after each Mac OS X 10.3 installation and Mac OS X 10.3.7 update.
You may want to try starting up from Mac OS 9.2.x Full Install CD instead of from (2) to (4).
Method 4:
(1) Find a desktop computer that has an ATA controller PCI card (SCSI environment) and has two hard drive bays. This will make your damaged drive appear as a quasi-SCSI hard drive. Mac OS 9.2.2 must be pre-installed on the computer. I recommend a host computer that installs an Ultra DMA/xxx or xxx (ATA-x) interface equal to or better than the damaged drive with backwards compatible.
(2) Set the host computer's primary drive as MASTER and your damaged hard drive as SLAVE and install the damaged drive in the second drive bay of the host computer. Verify properly configured jumper pin settings in advance.
(3) Start up the host computer from Mac OS 9.2.2. Launch the "Drive Setup" utility. Re-initialize the damaged disk on the second drive using the "Low level format" option. It may take hours but less than "Zero all data" option. Note: Normally, a low level format with a quasi-SCSI drive takes much less (30 - 40%) time than an ATA configuration drive. Note that "Low level format" fixes all difficult logical damage.
(4) Put the fixed disk back in your computer's drive bay. Re-configure the jumper pin setting to MASTER before you place it into the drive bay of your computer.
(5) Restart from Mac OS X 10.3 Panther full install CD. Re-initialize and re-partition it to install Mac OS X 10.3. Update to Mac OS X 10.3.7 via Software Update. Repair the disk permissions after each Mac OS X 10.3 installation and Mac OS X 10.3.7 update.
Note that Panther's Disk Utility does not implement a "Low level format" option.
Method 5:
If Method 4 does not work or fix the damaged drive, let me know. You may need an advanced technique to fix it if the drive is physically not a problem.
OPTION:
Purchase a known good hard drive that conforms to your computer's ATA specification. Fix the damaged hard drive some other time. Nowadays, prices of hard drives are inexpensive.

DIsk Utility: Won't properly verify boot disk?

Has anyone else noticed this, or is there something wrong with my Mavericks install?
If I try to verify "Macintosh HD" in Disk Utility, i.e. my boot disk, the verfiy doesn't perform the last 2 steps and doesn't confirm that the disk is OK.
For a normal disk, it says this:
Verifying volume “Data”
Checking file system
Checking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
Checking multi-linked files.
Checking catalog hierarchy.
Checking extended attributes file.
Checking volume bitmap.
Checking volume information.
The volume Data appears to be OK.
But for my boot disk, all I get is:
Verifying volume “Macintosh HD”
Checking file system
Performing live verification.
Checking Journaled HFS Plus volume.
Checking catalog hierarchy.
Checking extended attributes file.
Then the verify stops.
Anyone else noticed this?
Incidentally, I am MASSIVELY underwhelmed with Mavericks so far. It seems full of bugs and glitches and is altogether worse than 10.8 so far.

Yes, it's a known issue and bug reports have been filed. If you check the log you'll see that the Verify actually completed.
You can file feedback here. The more who file the more chance it will get done.

Disk Utility won't allow permission verify/repair

I have started getting some odd behavior from Disk Utility. I have one hard disk on my Mac Mini which I have never partitioned. When I open Disk Utility it shows the disk but not the partition under it that used to appear. When highlighting the main disk the options to repair/verify permissions don't appear. Occasionally when I start Disk Utility I do see the main partition but a small (200Mb)unmounted partition also appears. As I said I have never partitioned the hard disk so I don't know where this small partition is coming from. I can't seem to get Disk Utility to consistently show me the main partition that is supposed to be there. Can anyone offer suggestions for why this is happening and how to fix it. I recently moved from 10.5.6 to 10.5.8, but this problem appeared just before the OS upgrade. Thanks.

That is indeed strange behaviour. I'd try reformatting and repartitioning your hard drive with Disk Utility, and then restore your data from your backups. Make sure you keep your backups up to date after that.

How do I install Lion on an MBP with Snow Leopard 10.6.8, Boot Camp'd XP and a Master Boot Record?

I think this is called "a pickle."
The machine is a 13" MacBook Pro, 2.66 GHz Core 2 Duo w/ 4 GB RAM and a 500 GB HDD.
The HDD has a Snow Leopard 10.6.8 partition, and a Windows XP partition, via Boot Camp. Its Partition Map Scheme, sadly, is a Master Boot Record. I need to reformat it to a GUID Partition Table scheme to install Lion, but when I attempt to boot it from the Snow Leopard 10.6.0 DVD to wipe the drive, it grey-screens. Dead end.
From what I can gather on the forums, I can't boot a 10.6.8 machine using a Snow Leopard 10.6.0 DVD. I can't find my grey DVDs for this machine – still looking for those – but I expect those won't work either, being Leopard-generation?
The machine works fine, for the most part, including the optical drive. Has occassional display and wake glitches. Its HDD is backed up on a Drobo via Time Machine. I also have a 15" MBP Core i7 (with the exact same problem: 10.6.8, XP, MBR) which I can use for Target Disk Mode via FireWire. If I try to wipe the HDD on the 13", using Disk Utility on the 15" via Target Disk Mode, will the 13" then boot successfully from the Snow Leopard 10.6.0 DVD?
I just want to wipe the 13" machine, reinstall a fresh copy of Snow Leopard, then update it to Lion and restore from Time Machine, and never touch anything Windows-related ever again. (And then do the same for my 15", for which I've found my 10.6.3 grey disc. Not sure if that's any more promising.)
Any help appreciated!

Sounds like something is wrong with your disk. Have you tried cleaning it?
The Snow Leopard 10.6.0 DVD is fine – it mounts on both my 13" and 15", and I successfully created an image of it on my 15". I also tried my wife's Snow Leopard 10.6.0 DVD, also clean, which produced the same grey screen result.
Have you tried to use boot camp to erase the Windows partition?
Yep, this is supposed to be the proper way to remove a Windows XP partition from Boot Camp, so this was the first thing I tried. I get the same error as everyone with a Master Boot Record scheme appears to get:
The startup disk cannot be partitioned or restored to a single partition.
Back up the disk and use Disk Utility to format it as a single Mac OS X Extended (Journaled) volume. Restore your information to the disk and try using Boot Camp Assistant again.
So, if I can't launch the Disk Utility from the Snow Leopard DVD, my next best guess is wiping it from my 15" over Target Disk Mode. However, if I try that, and still can't get it to boot from the Snow Leopard 10.6.0 DVD, then I'm stuck with an MBP without an OS.
My conclusion – that 10.6.0 DVDs can't boot to 10.6.8 machines – was based on forum posts about downgrading from Lion. I was wondering if there's a way to create a "10.6.8 restore DVD," and try booting from that. Shot in the dark perhaps.

Disk Utility won't let me format external drive to FAT32

Maybe this cannot be done or the answer is simple and I am missing it. I have a 1.5tb Maxtor drive hooked up via fw800. I want to have 120gb of this as Mac OS extended journaled to back up my internal drive via Time Machine. I want the other 1.38tb to be in FAT32 so I can share files between my windows and mac machines. I keep all of my external storage except for the backup partition in FAT32. I have never had an issue until I upgrades to Leopard and now when I click on the larger partition I only have the option for the 4 mac formats-- FAT32 is not available. I can format the entire 1.5tb to FAT32 but once I try and partition it only mac formats are available. I forgot to mention I just did the upgrade to 10.5.1 and the issue is still present.
How do I format the smaller partition as mac os extended journaled and the larger as FAT32? Any help is appreciated.
Thanks so much,
Patrick
PS. I did a search but did not find anything.

It may depend on the type of partition table scheme you are using (see bottom of page in disk utility for that says Apple Partition Map/APM, GUID Partition table/GPT or Master Boot Record/MBR partition map).
MS-Windows can read MBR scheme only (64 bit MS-Windows supports GPT, according to MS). If you have Apple Partition Map, your disk won't be usable on Windows. I suspect you have APM partition table and hence the disk utility is not giving the option for FAT32 format, since you can't use it under MS-Windows.
On the Mac side, all 3 schemes are readable (for bootability, you'll need APM on PPC Macs, GPT for Intel Macs). Time Machine doesn't need a bootable disk, but I'd suggest APM/GPT if you are using PPC/Intel macs respectively (but I'd think either will work for Time Machine, if you have a mix of Macs).
But here's the catch - Apple says Time Machine won't work with drives with MBR partition map (even though Macs are MBR-aware), so the issue for you is Time Machine's ability to use MBR drives. http://docs.info.apple.com/article.html?artnum=306932
I suspect unless you are on an Intel Macs (OS X) and use only 64 bit MS-Windows (using GPT)/Itanium, using the same disk for TM and FAT32 sharing between Mac and Win worlds is not possible. Not the desirable answer.
If you do want to experiment, make a temporary setup and try it out on both Mac side and Windows side first (on all your machines), before making a "production" system. You can select the DISK (first line on Disk Utility for that disk, not second line) and click on Options at the left bottom (it might have to be erased first) and then select the type of partition scheme. Note formats like HFS+/FAT32 are a level lower in the hierarchy than partition map/table.
Let us know what you find out/decide?

Disk Utility Won't "Repair"

My powerbook has been running slow lately so I wanted to do a disk repair however Utility won't allow me to run the 'Repair' function. I can Verify and Repair disk permissions and also Verify the disk but the button for Repair disk isn't even active. My Hard Drive is archived if that information is pertinent.
Please let me know if you've had this problem before or know what I can do.

You can't repair the volume you've booted from, which is why that option is grayed out. What you'll need to do is insert the first OS X DVD that came with your system (or the first Tiger disk), and boot holding the C key down. This will boot from the DVD, and then you can choose disk utility from the menu bar, and repair the disk.
In addition, you may want to download OnyX or Yasu to run the disk maintenance routines, which can help with overall speed by cleaning up your hard drive. This also assumes there is at least 10% space free on your hard drive. OnyX can be found at http://www.titanium.free.fr/pgs2/english/download.html and Yasu can be found at http://jimmitchell.org/projects/yasu/ .

Am replacing airport extreme with Time Machine and want to upgrade from Tiger to Snow leopard. Am told I should manually back up into T Machine before OS update but set up utility won't allow anything with OS below 10.5 and I'm 10.4.11. What to do?

I think you mean you are replacing your Airport Extreme with a Time Capsule. Time Machine is software integrated into OS X 10.5 & 10.6 used to automatically backup a system to an external HD. Time Capsule is an Airport Extreme that has a hard disk integrated into it that can be used for storage or as a Time Machine backup drive.
Because you are currently on Tiger 10.4.x you can backup to a external HD using SuperDuper or Carbon Copy Cloner. Having a backup is very wise before doing any major system update. After you have created the backup and have successfully upgraded to Snow Leopard you can still use the external HD for many things. The strategy I'd recommend is to use the new Time Capsule as your Time Machine backup and then use the external HD as backup using SuperDuper or CCC. Redundant backups is wise because backups can (and do) fail too! In addition both SD and CCC are bootable clones, this is useful in that if your internal HD crashes you can boot from a cloned drive and continue working until the internal HD is replaced.
Below are some links to some articles from MacWorld, I would recommend reading them where you find a common theme, redundant backups. Backup Plan I, Backup Plan II & Backup Plan III.

Master Boot Record is greyed out, so how to use?

How do I use Master Boot Record (in Mountain Lion, to partition an external Seagate Backup+ hard drive) when it is greyed out and I can't choose it? I tried turning off Time Machine, but that didn't do anything. I also tried installing various Seagate software (like HFS4Win.exe) because what I really want to do is use one partition on the drive as back up when I'm using the Mac OS, and the second partition as back up when I'm in Windows 7 (with maybe a third partition for storage for either/both - it's 3tb). I've spent a few days at the Seagate page and nothing suggested there works, but re-formatting the drive with Master Boot Recorded sounds promising, and it won't let me!
If anyone has a solution please let me know! I'm reasonably adept!

Hi Lee,
If "Manage Catalog" option is greyed-out, it may be possible that you are in the "eLive" room. As in "eLive", most of the File option are displayed.

10.4.11 Installed -Safari Crashes, Disk Utility Won't Open

Installed 10.4.11 yesterday via software update on our 2.0GHz Core Duo Macbook Pro.
After installing Safari crashes seconds after opening (it freezes then crashes) and then I downloaded the 10.4.11 update from Apples website (using firefox) but Disk Utility won't open it. If I try and launch disk utility myself it just bounces in the dock once and closes. Please help!

Same here - two identical iBook G4's, both updated to 10.4.11 - one is fine and everything works, the other one has the following problems: safari crashes 100% of the time, USB devices are failing to be recognised (mouse, storage key etc).
Looking in /var/log/system there is an error message saying a previous version of a kernel module is already loaded (cant get to the original error message text sorry!).
Looking on other forums looked like a simple 'trash the cache' fix - which I did - and hey presto the usb devices started working - but not safari. Messing around trying to flush out a safari cache failed after a few attempt, as did fixing file perms, zapping PRAM, booting from open firmware, and all the other usual things mentioned in the forums.
As it happens the iBook has nothing precious on it - so though to reinstall from the original installation disk. iBook G4 specific OSX Tiger distribution disk 1 inserted, but iBook now refuses to boot from it - holding down the c key on reboot just pops up a blue screen with a folder icon on it and an alternating finder and question mark logo - as in 'error I can't find a system on this installation disk' - the iBook then boots from the internal disk - getting nowhere fast.
Out come the Leopard install disks, and iBook quite happily boots from there and is right now doing a clean install from them (like I said nothing precious on there and thats why I cant get to the original error message...).
I've seen lots of posts about folks struggling to boot from the original install disks recently - wondering if patch 11 did something to knock the OSX version number on the machine greater than the version on the shipped G4 install disks??
And there is something very odd about patch 11 that seems to have hit this iBook and not my other one - they both installed fine, they have identical software apps on them and they are both the same spec.
Can't help more than this - but given I've seen these issues raised in several places worth adding to the thread.

How to set up Apple Partition Map not to be a Master Boot Record

Hi.
In order to copy Leopard install disk to a flash drive I need format the 8 G Cruzer (on which the U3 was removed) to set up Apple Partition Map not to be a Master Boot Record to be bootable on my Quicksilver G4. I never used partitioning before, step by step please.
W.W.

Hi, motsteve -
Forget booting USB on any G4
USB booting is possible on all G4s and later models starting with the G4 (AGP) models, per -
Article #58430 - USB Info and Benefits of Dual-Channel USB
I think I read somewhere (couldn't find it just now) that the earlier versions of OSX are not USB bootable, so booting to USB on G4s might need to be by using OS 9.
I've never tried USB booting. However, I have made a bootable Zip100 disk for my G4/500 (AGP), using its internal Zip drive. Did it just to see if it would work - it does. There's a fair amount of room left over on the 100MB disk, too.
Intel-based machines are also USB bootable, per this article -

Help ,Disk utility does not allow me to partition my internal HD

hello , i want to partition my internal hard drive but for some reason disk utility does not allow me to , when i click on the partition window everything is greyed out, i read on other thread that file vault might be the problem but is already off , i can t figure out what the issue is any ideas ??? here is a screenshot.

Not if you want to be able to restore the Boot Camp partition using Boot Camp Assistant. There are alternative boot loaders you can use to add Windows and Linux to an OS X drive. You would first need to restore your drive by deleting the Boot Camp partition you now have. Then take a look at The rEFInd Boot Manager: Getting rEFInd - Roderick W. Smith.

Desktop or Disk Utility won't show External Hard Drives

The Desktop or Disk Utility won't show 2 of my old external hard drives and so they are currently unsusable. My computer however recognise other external drives.
320GB Western Digital MyBook Premium model number: WD3200D032-000
500 GB Western Digital MyBook Premium model number: WD5000E032
I have same issues both of these external drives.
The blue circle lights come on so power is getting to it.
Tried 2 USB cables, one I know for sure is working - Nothing.
I am using Lion 10.7.4 on a mid 2009 13" MacBook Pro
All efforts to help much appreciated

No they haven't worked on this computer before. I using them on my old MacBook Pro (a computer which is no longer working) which ran Snow Leopard.
The 500GB drive "stopped working" with that old MBP too
But the 320GB drive was always working with old MBP if I remember correctly.

Disk Utility won't start up in 10.5.3

I have been unable to open up my Disk Utility at all. I was able to do so earlier, perhaps with 10.5.0 while I was mounting my external hard drive. Now, I cannot mount the hard drive, and therefore cannot use Time Machine all because DIsk Utility won't open. I've diagnosed my hardware with "Disk 1" and found no problem. And, I've reinstalled the operating system. Any ideas?

Chris:
I just had the same issue on my son's MacBook. As long as you have a wired keyboard, the following will work.
1. Shut down the computer if it is on.
2. Press the power button to start the computer.
3. Immediately press and hold the Command (Apple) key and the "s" key for single-user mode.
4. Type mount -uw / (then press the Return Key) wait for next line to appear with # root/
(there is a space between t and - and another space between w and /)
5. Then Type "passwd" (without quotation marks then press the Return Key)
6. Enter new password (this will be for the root user account) (watch your fingers when you type because it doesn't show what you are typing, then hit the Return Key after you type it.
It will prompt you to retype the new password again, so retype it again and then hit the Return Key) wait for next line to appear...
7. Then Type "reboot" (without the quotes and hit the Return Key)
after the computer restarts and comes up with the login window....
8. Login with any of your usernames just to get the desktop up.
9. After desktop comes up choose System Preferences, then choose accounts. Unlock if you have to and using the username: root ..... and the password you just setup in the single user mode You now should be able to make users including your existing user account an admin.
After you log back in under your real account, it is advisable to deactivate the root user account. To do this,
1. Click the Finder icon in the Dock.
2. From the Go menu, choose Utilities.
3. Open Directory Utility.
4. Click the lock in the Directory Utility window if you need to unlock the utility.
5. Enter an administrator account name and password, then click OK.
6. Choose Disable Root User from the Edit menu.
Hope this helps.
