OS X :: Reformatting The Internal Hdd Partition Table?
Sep 12, 2009
I've always just read them, but I need specific help this time! I have a 1st generation 13" white macbook with 2gb of ram and a 2ghz processor. I upgraded my internal hard drive to a 500 gb hard drive, and when I did that - for some reason, the default partitioning table was an apple partition. Now that I'm trying to install Snow Leopard, it says I need a guid partitioning table. I've cloned everything to an external drive, and I'm ready to reformat the partition table of my internal hdd to guid, but disk utility can't unmount the disk.

Have a macbook pr 17 with bootcamp.
the osx 10.6 partition is giving errors (the black and white multi language message that tells you to hold down the power button..)
have done a permissions repair, run techtool from a boot disc, all have failed to repair.
next step is for me to reintall snow leopard, and as i have no dual layer disks or usb keys i intend to install from external usb drive using the instructions here:
http://osxdaily.com/2009/09/02/insta...t-a-dvd-drive/
But how do i format the drive from within windows as boot recognisable from mac?
i have partition magic and cannot see ny option for osx extended or �GUID Partition Table?

recently i gave first ubuntu and then windows 7 a shot on my macbook. i partitioned the drive using bootcamp, then repartitioned the non-OSX-part with the ubuntu and windows installer. At the moment windows and OSX ar on my macbook, both are bootable and work, though the partition table in OSX' diskutil seems messed up. It shows that there is still a linux swap partition left. The windows NTFS partition is mounted on bootup but shows random (not human readable) folders in finder. Windows in contrast shows the partitions as they should be (and probably are, considering everything is working). How can i fix the partition table seen by OSX? How can it be that windows and OSX dont show the same partitions?

I am reformatting an internal hard drive in an enclosure to use as a media storage drive. I attempted to reformat the drive and partition it as a Mac OS X Extended however it will not erase the current volume and reformat. The volume on there currently is literally the HD with the old OS and Files and such on it, so am I missing a step in the reformatting process? Do I need to reformat as Free Space or FAT or what?

After getting Windows to reorganize my 2TB HFS+ partitions, I decided to create a small 300 GB partition on one of the volumes and format as NTFS for use in Boot Camp. I did this with iPartition (which was very easy), and when I booted into Win7 - all my HFS+ partitions, and the new NTFS partition were visible to Win7. I was a happy camper. After playing around in in windows for a while, I booted back into OS X, and much to my horror, all the HFS+ partitions on that drive, *except* for the new NTFS one, were not there! iPartition just shows a 300 GB contiguous space called Windows Work. In fact, my 2TB drive is now a 300 GB NTFS drive with a little free space. The rest of the 2TB's are gone....in OS X that is. I really need to get this data back so I can use it in OS X, so could anybody please tell me what I did wrong and how to get this volume's partitioning back to the way it was.

I think at one point (probably when I switched from my 80GB to my 500GB drive) I screwed up and made the partition format on my drive Apple Partition Format. As I was just doing disk cloning, Leopard had no problem with this, and never mentioned anything being wrong (if it did I could have fixed it back then). However now, when I try to upgrade to Snow Leopard, it complains about this, telling me I can't upgrade and my only real option is to back up my data and fresh install. Problem being, I don't have a 500GB drive laying around, and I don't have the money to buy a 500GB drive to use once to back up all my data. It pisses me off to no end that Leopard didn't complain about this when I first did it if it was going to be a problem in the future (back when I could have fixed it) and only now it's become a problem. I guess my question is, is there any way I can get by this problem and install Snow Leopard? Or am I gonna have to wait till my friend needs to wipe his PC again and borrow his HD for a night?

So much for upgrading... Does anyone have a fix for not having a GUID partition table scheme? I was hoping I wouldn't have clean install, I just got everything how I wanted it. *sigh*
Something tells me there's no way around this.

I decided I want to make my Mac HD one whole partition again but I don't know how to do it. I had tried using boot camp, but it was giving me an error. So I cloned my HD and now I've booted into the clone and am wondering how I can delete everything on the Mac HD and reformat it into just one partition. I tried searching but couldn't find it.

I'm planning to reformat the osx partition and I'm wondering if the bootcamp (or any other) partition will be affected. I'm not sure how it works... Or can I only reformat the whole hard drive?

I've got a Mac Pro (early 2008 edition) and I installed Windows 7 via boot camp. I no longer use the OSX on the main partition because I boot OSX on this computer from an external drive.
I would like to format the main partition (where my old OSX is) so I can use it for file storage from both OSX and Windows, but I'm afraid I might screw up the boot capabilities by doing so. Can anyone confirm that my Windows 7 boot camp partition will still boot successfully after formatting my old OSX partition to FAT32 (or whatever makes the most sense)?

I'm having problems installing OS 10.6 on my iMac. I had to replace my hard drive with a new 1TB drive and in trying to install the OS I get a message saying I need to use Disk Utility to repartition the hard drive using GUID Partition Table but I don't see any such option in the Disk Utility menu!

A while back i decided to get bootcamp up and running on my macbook. that's all and good except i made it a 20gig partition, which is good for practically nothing. i would like to increase it to 50 gigs or so and my computer wont let me do that. So i've decided to go with a back up on a 500GB western Digital Elements and start over new.

Despite reading several post saying its not supported by Apple, i decided to give a try on installing Win7 on my MP 1,1 and stumbled through some unexpected problems. First I used BootCamp3 and split one of my HDs into winBC partition/Mac partition, then restarted Windows 7 install. I stumbled into the first problem which was the installer, after reformating the BC partition, displayed an error code, 0x80300024, a hard drive problem error in fact. The solution to this was quite simple, the BCpartition was on drive#4in slot #4, i had to move this drive to slot#2, then the installation runned smoothly. When rebooting and starting Windows for the first time (finishing the installation), I saw the Windows animated logo then the screen went black and hanged and lead to a BSOD. The message is 0x00000116, a graphic problem. I tried booting in safe mode but it says I need to let Windows 7 installation finish before booting safe mode and since i cannot finish it, beacause of that BSOD... So its a no go for now. I ran into instructions 'Instead, restart and press a key to boot from the Windows 7 disc when prompted. Rather than running the installation again, choose the little option at the bottom to Repair your computer. Decline any suggestions that pop up until you see a list of options with Command Prompt at the bottom. Choose that option. At the Command Prompt, type DEL C:WINDOWSSYSTEM32DRIVERSATIKMDAG.SYS to delete the default ATI driver, then close the window and reboot. This time, Windows should successfully initialise a more appropriate display driver, allowing you into the desktop.'at [URL:...]These instructions are for the BC problems on the Imac, not the MacPro. However i ran into the same problems, so i tried the same solution. Unfortunately, the Dos command does not work. I feel the installation is close at hand, and very possible, we'll see later for the Bootcamp xtensions, Has anyone stumbled upon the same problem/ or has a remedy?

I have a 320GB internal drive on my Intel Mac Mini. I tried to make a windows partition using Boot Camp. After I dragged the slider to select the partition size (100GB) and hit 'next' it didn't work. A message came up and basically said it failed. I don't remember what the message was exactly, something like "Verification failed. Some files could not be moved." But now, my Mini thinks it only has a 220GB drive. I open Disk Utility and I tried to reformat but it will only go to 220GB. It seems I lost the other 100GB.

I would like to reformat my previously partitioned startup drive into a single partition. (G4 dual 533 running OS 10.4.11) I have carbon-cloned the startup drive contents to an external fire-wire drive which I hope to re-transfer back after reformatting my original drive into a single partition. I have designated the fire-wire drive to be the new startup disc.

Is it possible to reformat a single partition of a disk w/o reformatting the entire disk?Or must one reformat the entire disk? In DU, If I click on the volume/partition in question, I do NOT get the tab “Partition.” If I click on the disk, not just the volume/partition in question , then I do get the tab “Partition.” Also, does using DU to secure erase a volume by overwriting with 0s, cause a format issue? Some details on my other post:Create a bootable clone using Disk Utility

I have a new iMac 27" w OSX.6.2, 2.66ghz intel cor 15, w 4 gb RAM and a 1 tb internal HD. I have final cut xpress3.5, live type and sound track loaded onto it, besides the stuff that came with the package.
I have five separate external hard drives. Two of them are hot swap 800 enclosures for which I have 5 hot swap trays. I have about 3 tb external storage all together.
Is there any reason to partition the internal HD? I could get 4 250 gb partitions; or any other configuration. I have never done an HD partition, so I need some guidance about how to do it, if it is a good thing.
My thought is to use an external HD for scratch disc, and use one of the partions for "Time Machine" back ups. I realize that this is sort of silly, since it is still the same internal HD that is doing all of the heavy lifting for program operation. But this thing comes with 1 tb of HD space for some reason. I wonder why, if not to store something besides programs and audio render files.
I read that any 400speed external HD in a system will slow all of the faster drives. So my thought is to use only the hot swap 800 enclosures and hot swap drives with the new iMac, and leave the older 400 speed drives plugged into my iMac G5.
I could put the time machine back ups on one of the hot swap drives, but it would have to be plugged into the new iMac all of the time and I would lose the ability to drag (QT) files from that drive, to the other hot swap drive, or into the browser of FCX.
Could I set time machine to back up only on order? Then I could still use the hot swap enclosure with any one of the hot swappable drives, and use another external drive as a scratch disc and have them daisy chained into the iMac. I could back up at the end of every work session.

I am trying to create a partition on my internal HDD on 10.4.11. I have tried two ways.
Terminal way $ diskutil partitionDisk disk0s3 1 HFS+ rigantaHFS+ 15G
- That returned an error ( i would say plausible) " couldn't unmount disk for zeroing" " couldn't unmount disk (-1000) on disk0"
- i did try the same command line in single user mode but that did yield anything at all. I got the same error message.
Disk Utility (/applications/utilities/diskutility)
- I basically cannot partition my internal HDD without erasing my the entire HDD
- So my question is :"how to create another partition on my HDD, without erasing the entire HDD?"
I am using a PPC with tiger 10.4.11
PS: the reason why I am not using the disk utility on the install DVD is that I have lost them.

What is the best way to make a FAT32 partition on a MacBook's internal hard drive? (I plan to use it to share files between OS X and Windows.) I did some research on this, and some people say to use Disk Utility, however, the only disk format available for me is "Mac OS Extended (Journaled)" and there are no FAT32 or FAT or MS-DOS options. Perhaps those options were taken out since then(?). One other person said to create the partition using Windows, which I think would work, but I'm a little worried about that because I've read that editing partitions outside of OS X can prevent Boot Camp from seeing the partitions.
I'm thinking that my best bet would be using Windows to shrink its own partition, then turning the resulting unformatted space into a FAT32 partition. Since I'm not touching the OS X partition I'm hoping there wouldn't be any problems. I just wanted to confirm whether or not that would work and/or what a better method would be.

I have MBP 17", 2,53GHz, hdd is 250GB. I have a lot of music and pictures and quite lot movies. On the other side I have a lot mails. Is it better to make two partitions and keep them separate? What is your suggestion? If I decide to do that, do I need to remove everything from hard drive to make another partition? I never did it before on mac, but I remember that is necessary on windows.

I've recently experienced my 2013 MBP 13" getting slower and as the HD was getting full I decided to upgrade from 500GB to 1 TB.
The first disk i tried was the Seagate sshd slim hybrid disk. This disk was fine (and bootable) in an external USB enclosure, but once I cloned my MBP (using CCC) and mounted the disk internally it wouldn't boot. I tried formatting the disk using disk utility, both booted from the original HD i the usb enclosure and via the online recovery system. All to no avail. Disk utility kept giving error messages saying "can not make disk passive"(roughly translated from Danish).
At that point CCC tech support told me to get a new HD as he was certain it was faulty.
I did just that but now the new (WD blue 1 TB) drive can't be formated as well. I get the error: "wiping volume data to prevent future accidental probing failed"
I am at a loss as to what to do. The MBP works fine, albeit slow booted from the original HD, but I can't seem to partition any new drive.

I have a 13 inch Aluminum Late 2008 MacBook. Processor 2 GHz Intel Core 2 Duo, Memory 4 GB 1067 MHz DDR3, Software Mac OS X Lion 10.7.4 (11E53). Currently I have a 160 GB SATA disk as my hard drive a d 4 GB of memory. (Is it time to upgrade or what?) I recently bought a Western Digital 1 TB internal hard drive to replace my exisiting internal hard drive. I spent a lot of time last night trying to first- connect this new hard drive to my computer so that I can then clone the existing hard drive and then hoping that I would get that done so I could install the new hard drive. No such luck.
My current hard drive is partitioned as follows:
Name: Macintosh HD
Format: Mac OS Extended (journaled)
Size: 132.5 GB
Name: BOOTCAMP
Format: Windows NT File System (NTFS)
Size: 26.69 GB
When I was partitioning the new drive I did so as follows:
Name: Macintosh HD
Format: Mac OS Extended (Journaled)
Size: 973.51 GB
Name: BOOTCAMP
Format: MS-DOS (FAT) --- This was the only option that I was given that I thought would work. I did not have the option of "Windows NT File System (NTFS) to choose from. Question # 1: is that going to be a problem? I only run 1 program on Windows and that is the only reason I have BOOTCAMP on there at all. However, I do HAVE to have that program. Like I said it didn't give me the option to choose Windows so I didn't know where to go with this. Any help with that would be awesome.
Size: 26.34 GB (I just used the same size that was current, or close to it.) I connected the Western Digital 1 TB through an external device, partitioned it as stated above, and then used Carbon Copy Cloner to clone the drives. The first one went through fine. (It took 2 hours and I went to bed before it finished.) This morning I woke to see that it had gone through well. I then started the process with the BOOTCAMP drives. However, before I started it gave me errors stating that I wouldn't be able to run Windows off of the Cloned BOOTCAMP drive. Question #2: Is it because of the Format type I chose when partitioning?

Ok so I am making a presentation using Keynote '09. I have one slide that has a huge table of different appliances and their cost. Here is what I would like to do: the first row is entitled "refrigerator". I would like there to be one slide that just has the table title and this first row. Then I would like to show the next slide, which has pictures and descriptions of the specific refrigerator on it. Then, the next slide would be the table again, except this time another row would appear, in this case entitled "heating", then I could show the next slide which has info about the heating system, etc., etc. I have used Magic Move (and love it btw), but that can only be used on the slide right after the target slide, so that would not work for this since they have a slide in between them. I have no idea if this is possible, and maybe the only way to do this is to make a different slide every time, but if there is an easy way to do this that would be awesome!!
