Diskutil repair all partitions of disk1 (external drive)

Is there a way to run diskutil on all partitions at once rather then me doing them separately. Disk1s10
These partitions are on an external drive
Example
diskutil repairdisk /dev/disk1
Or
Diskutil repairvolume disk1
And so forth
I get unrecognized volume error -9958

Don't believe there is a repairdisk command there is verifyvolume and repairvolume. If its your root drive you''re trying to access try /dev/disk0s2 otherwise do
diskutil list
to display the know volumes

Using Disk Utility to create a partition on an external drive

Hi Everyone
I have a 250gb external HD drive which is currently split into two partitions of Fat32. I'd like to use this drive for storing images of OS X, but when I tried to create an image using the OS X startup DVD, I was told that FAT32 didn't allow large enough file sizes (or something along those lines) in order for me to backup my OS X.
Disk Utility appears to offer the ability to split partitions on the external drive, i.e. I can select the largest of the two partitions and choose to split it into two 96gb partitions. However, will this be a destructive partition process, and can I reasonably expect my external hard disk to be reformatted with a 96gb Mac OS X formatted partition whilst still keeping two FAT32 partitions and all the data that resides on them?
Any help is much appreciated!

You will not be splitting existing partitions. Instead, you will be creating a new partitions from scratch.
Run Disk Utility. Select the hard drive to be partitioned. Make sure you select the hard drive in the sidebar, not the volume indented below the drive. Go to the Partition tab. If you want one or more of the partitions to be MS-DOS, you must first click on the Options... button. Select the Master Boot Record option and OK. Select Volume Scheme of 3 Partitions. Now set up your three new partitions as you want them, in terms of size and format. For the Mac partition, select Mac OS Extended (Journaled) as the format.

Can i have my windows partition on an external drive?

hello all,
alright, so im looking at a laptop for college and after much research and a few trips to the apple store i want the new, 13-inch macbook pro, with retina display and a 256GB flash hard drive. i love this computer in every aspect except.... you guessed it, its small hard drive. i can always get external drives to make up the differance though, and their is always the cloud so i dont think ill have too much of a problem. but i do need to use some software for college that is only windows based. so rather then splitting up this already small hard drive can i just install windows onto my mac (because i already know i cant put windows on an external drive with boot camp) and make the entire windows partition on the external drive? this way im not losing any native space besides that used to hold windows and im not installing windows to an external drive so hopefully bootcamp wont have a hissey fit. can anyone tell me if this will work? or if this wont work can anyone give me any other solutions to having windows on my mac without splitting up my native hard drive? such as installing windows to my mac and making the partition in the cloud or something? just anything so i dont have to split my already small, yet extremally fast, 256GB hard drive.

You can install Windows on your internal drive and store your Windows data on any drive you want to use. Keep in mind that any Windows programs you install in Windows will be installed on your internal drive. So make the Boot Camp partition large enough for Windows and any programs you may install now or in the future. You will also need room for swap/page files and other activities such as installing Windows updates.
100GB will likely be a good size for the Boot Camp partition given that it is unknown what programs you will be installing.

Best way to set up partitions on 250GB external drive

Hi all,
I've decided to go with an Iomega eGo 250-GB FireWire portable drive to back up my iBook's hard disk (30 GB) plus to store my photos and maybe hold a bootable copy of OS9.
This is my first time using an external drive, so I don't really know how to go about setting things up.
What would be the best way to set up the partitions on the external drive?
1) I know I should create a 30GB partition for the iBook backup, but what about for the remaining volume? Is it best to leave it as a single large 200GB partition, or split it into two 100GB chunks? Other than the clone of my iBook, I'll mainly be storing photos (at the moment no more than around 10-12GB).
2) I don't yet have a huge iTunes collection, but if I later want to store iTunes music that doesn't fit on my internal drive, is it fine to put it in the same partition as the photos, or would it be preferable to create a separate partition?
3) If I want to install OS9 on the drive, how much space should I allot to it? Would this enable me to run legacy apps on my iBook?
4) Does it matter how I name the partitions (i.e. should the name for my iBook back-up be the same as the original volume or should it be different?)
5) As I still don't know exactly what I need, If today I decide to create only 30GB partition to backup the iBook, can I later partition the remaining space without having to start all over again?
6) Also, the drive came out of the box with Mac OS Extended format. Is this the best format or is there another that would be better?
Thanks for any advice

The answer to both question is that it's completely up to you. Partitioning or not partitioning won't affect operation significantly.
3) If I want to install OS9 on the drive, how much space should I allot to it? Would this enable me to run legacy apps on my iBook?
The iBook G4 can not boot from OS 9 so you would only be able to run OS 9 in the "classic" environment.
4) Does it matter how I name the partitions (i.e. should the name for my iBook back-up be the same as the original volume or should it be different?)
No
5) As I still don't know exactly what I need, If today I decide to create only 30GB partition to backup the iBook, can I later partition the remaining space without having to start all over again?
There are a few tools which promise the ability to change the partitioning without destroying the data on the drive. But you should never do this without making a backup of the data on the drive. Data loss can easily happen and in a big way.
6) Also, the drive came out of the box with Mac OS Extended format. Is this the best format or is there another that would be better?
That is the best format.

Clone a Mac Partition to an External Drive from within Windows 7 Bootcamp?

Anyone know if it is possible to clone the mac os x partition to an external drive from within Windows 7 bootcamp? I (like a few others) had a problem with the latest 10.6.3 update and I cannot boot into the mac partition but I can access it via bootcamp so I was thinking about trying to clone it to an external drive and then boot from the new clone and see if that works.
Appreciate your comments.

setup a 30GB partition on an external drive, along with a partition of 150% the size of your Mac OS X volume -- or larger.
Install OS X to 30GB.
While booted from DVD, before you install, you'll need to go to Utility Menu => Disk Utility to do the partitoning. While there, in DU see if you can repair your system.
And where is your TimeMachine or clone backup? The "Step #1: Backup before beginning your Boot Camp project."?
No way to backup or clone from within Windows, though you may be able to write to NTFS backup volume, UNLESS you bought MacDrive8 which allows read AND write to HFS+ from within Windows.

How to download all songs from my external drive into my itunes library

I have enough Gbytes to not use an external drive for my music.
How do I proceed to download all songs from the external drive on my internal drive?

Hello there, Laetidela.
The following Knowledge Base article offers up some great steps on how to move your iTunes library from an external hard drive to your computer:
iTunes: How to move your music to a new computer
http://support.apple.com/kb/ht4527
External drive
This option requires more work than Home Sharing, but it creates a backup of your iTunes library on the external drive in addition to moving your content.
Notes before you start:
You can use most iPods as an external drive.
Windows operating systems don't recognize Mac OS-formatted disks (HFS or HFS Plus formats). Because of this, you can't use a Mac-formatted iPod or external drive to move your music to a Windows PC. See iPod: How to determine iPod's hard disk format if you're not sure how your iPod is formatted.
Mac OS X can read Windows-formatted iPods and drives. This means there are many ways to migrate your information from your old Windows-based PC to your new Mac.
Mac OS X: To be sure external drives appear on your desktop, choose Preferences from the Finder menu. Be sure the options for "External disks" and "Hard disks" are enabled.
Part 1: Locating and consolidating the iTunes Media folder
Part 2: Copy iTunes folder from the old computer:
Part 3: Get iTunes ready on your new computer
Part 4: Back up any music that's already on your new computer
Part 5: Copy music to your new computer
Part 6: Add preexisting music that was on the new computer back into the library
Thanks for reaching out to Apple Support Communities.

Is it possible to store all photos in an external drive? How do I do it?

I have too many photos to store in my MacBook. Is it possible to store all photos in an external drive and still use iPhoto (or Aperture) to view them all?

Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

MacBook Air, can I partition my Mac external drive to have an ISO image file location for Windows downloads?

Hi, in preparation for installing bootcamp and windows 7, and in the absence of a DVD drive on my MacBook Air, can I partition my Mac external drive to have an ISO image file location for Windows downloads?

Can't boot from Windows partition or any external drives...?

My iMac just stopped booting from both my boot camp partition, and any external drives. I tried booting from a bootable flashdrive with drive genius installed, but it just booted OS X. Despite holding TAB, it just boots normally, as if I wasnt even holding it. I also tried installing rEFit, but OS X still ignores it and just boots normally. What's going on?!

...wow....nevermind, i just realized that i was hitting tab not option...good lord...ive been running boot camp for a long time too...alright well...thanks anyway lol

I am trying to back up a Mavericks partition to a partition on my external drive.

I am trying to back up a Mavericks partition to a partition on my external drive. I have erased the partition on the external drive but I keep getting an error message that the back up drive is full. I also have Snow Leopard backed up to the other partition on the external drive. When I first tried this, Time Machine tried to back up the entire MacBook Pro drive on the same external drive partition. It's as if it doesn't recognize the Mavericks partition on the Mac drive. Also, I can't delete the empty partition on the miniStack external drive.
Any help will be appreciated. Thanks!

How can I mount a Raid set (partition in an external drive)?

Hi,
I have 3 partitions in my external drive. I tried to create a concatenated Raid from 2 of the partitions. However, I end up with an offline Raid Slice (one of the partitions is under this slice) which is grayed out in Disk Utility.
When I try to delete the Raid Set, I get "Deleting RAID set failed. This RAID configuration is not valid" warning. When I try to erase the RAID volume, I get "Volume Erase failed with the error:The chosen size is not valid for the chosen filesystem." warning. I cannot mount the volume either.
So, I have 2 of the 3 partitions mounted. The 3rd partition (which is under RAID) is unmounted. Do you have any suggestions to have access to the 3rd partition?
Thanks.

Why are you trying to RAID two partitions on the same drive? Aside from the fact that it doesn't work it also makes no sense when you can simply create a larger partition by joining the two into one.

Success: moving bootcamp partition to an external drive

Background
Due to the relatively small, non-exchangable SSD on my Mac, I'd limited the bootcamp partition to 50GB when installing Windows. I needed to install new software in Windows, but was running out of space fast and didn't have the necessary space on the Windows side. I don't use Windows that often and for that reason, I wanted to move the Bootcamp partition to an external hard drive, freeing up space for the Mac side on the internal SSD. I'd read many conflicting reports on the web, some claiming they'd done it successfully, while others said it would be impossible, because Windows 7 wouldn't run from an external drive. I had a HDD in a USB 3 enclosure, and first tried to install Windows to this (using various guides on the web). I was very close to success with this USB 3 drive, but Windows would fail during start-up. Most reports claiming to have successfully been able to run Windows 7 from an external drive, had used Thunderbolt drives, so I decided to get myself a Lacie Rugged USB 3/Thunderbolt series Solid State Drive.
Hardware used
MacBook Pro 15" Retina Display (mid 2012), 2,3 GHz Intel Core i7, 8GB RAM, 250GB SSD
Lacie Rugged USB 3/Thunderbolt series, 120GB Solid State Drive
Software used
Mac OS X Mavericks, 10.9.2
Windows 7 Ultimate
Plus several free downloads from the internet, see description below.
Procedure
Step 1: Get the Thunderbolt drive to work under your Bootcamp Windows 7 installation.
This should be simple enough, but proved to be a little tricky. Here’s what I did (assumes you are running Mac OS X before you begin):
1. Make sure your Thunderbolt drive is disconnected before proceeding.
2. Restart your Mac and hold down the option key (alt key on some keyboards) during startup.
3. Choose the Windows drive to start up Windows 7 on your Bootcamp partition.
4. After log in to Windows 7, download the necessary driver software for your Thunderbolt drive (find it at the manufacturer’s homepage of your Thunderbolt drive - in my case lacie.com).
5. If the downloaded driver installer is in a compressed format (like zip for example) be sure to decompress it before running the driver installer.
6. Shut down your computer.
7. Connect your Thunderbolt drive to your computer.
8. Start up in Windows 7 (see items 2 & 3 above) and if it all went well, you should now be able to see your Thunderbolt drive under Start>Computer.
Step 2: Format your Thunderbolt drive in NTFS-format.
Still running Windows 7 with your Thunderbolt drive connected and visible to the system, it is now time to format your external Thunderbolt drive in NTFS-format. There are several ways of doing this. I used the procedure described here at tedhhack.co.uk.
Step 3: Follow the directions at intowindows.com to clean install Windows 7 onto your external Thunderbolt drive.
As described at intowindows.com, this involves downloading Windows Automated Installation Kit (WAIK) and running command line tools. At step 9 in the described process at intowindows.com, at the point where the installer asks if the drive you are installing to is a USB hard disk, the correct input is Y for yes, even if your external drive is a Thunderbolt drive (and obviously not a USB hard disk).
At step 10 in the described process at intowindows.com (Reboot your PC), remember to hold down the option (or alt) key at every restart in the installation process, so as not to start up in Mac OS X. Also, since your machine now has two Windows 7 installations, Windows Boot Manager will appear and ask you to “Choose an operating system to start” and there is a list of two Windows.
I don’t know how to tell which one is on the external drive and which one is on the internal drive at this point, but I started with the top one on the list and this turned out to be the one I wanted (the newly installed one on the external drive). If you pick the wrong one (on the internal drive) at first, simply restart the computer and choose the other one. You know you got the right one when the installation process continues and asks for further input.
After the Windows installation is complete (there will be at least one other restart required - remember to hold down the option (alt) key to start up in Windows, and choose the same Windows on the list in the Windows Boot Manager), you’ll be running a freshly installed, but crippled Windows 7, as you still haven’t installed the specific drivers for your hardware. But don’t worry, that will be fixed in the next step.
Step 4: Clone your Bootcamp partition from your internal drive to the external Thunderbolt drive.
In this step you will copy all the software, drivers, settings and other files from your Bootcamp partition on your internal drive to your external Thunderbolt drive. The easiest way to do that is to clone your Windows partition - and to that end you’ll need to download some free software: AOMEI Backupper Standard 2.0 fits the bill perfectly, as it will let you clone at the same time as resizing the partition to fit your external Thunderbolt drive (I went from a 50GB internal Bootcamp partition to a 120GB external Thunderbolt SSD).
1. Download AOMEI Backupper Standard 2.0 (I used the 17MB download for Windows 7), install it, and run it.
2. In the left column choose “Clone” and in the right column choose “Partition Clone”. By choosing Partition Clone instead of Disk clone, you won’t ruin the newly created (but invisible) boot partition on the external Thunderbolt drive.
3. Press Next and choose your internal Bootcamp partition as the Source Disk.
4. Press Next again and choose your external Thunderbolt drive (your newly installed Windows 7) as the Destination Disk.
5. Press Next again and you’ll get a warning that you will erase the contents of the destination partition and it asks if this is what you really want to do. Press Yes to this question.
6. Next screen is an Operation Summery. Toward the bottom of the Operation Summery screen there are a few interesting options: Edit Size of Partition, Clone Sector by Sector and Align Partition to Optimize for SSD.
7. If your destination partition is larger than your source destination like mine was, press Edit Size of Partition. This will take you to another screen, where you can drag to resize the partition. I dragged this all the way to the right to give Windows 7 the full size of my external Thunderbolt drive.
8. Leave the checkbox Clone Sector by Sector unchecked.
9. If your external Thunderbolt drive is an SSD, put a check in the checkbox entitled Align Partition to Optimize for SSD.
10. Now press the Start Clone button.
11. When the cloning process is done, exit AOMEI Backupper and restart your computer (holding down the option or alt key) to start up in your new clone of your old Windows 7 with all the same software, drivers, settings and files.
Step 5: Enjoy running all your Windows 7 applications from your external Thunderbolt drive!
Step 6: Here is where I need help/advice – can I remove the Bootcamp partition on my internal drive now?
I am reluctant to entirely remove the Bootcamp partition from my internal drive, as I am unsure whether this will disable me from starting up in Windows. I would love to hear from anyone here with insight on the matter.

Step 6: Here is where I need help/advice – can I remove the Bootcamp partition on my internal drive now?
To answer my own question in Step 6 above, no, or at least I haven't found a way yet...
Here's what I've done so far:
Used the Bootcamp Assistant to remove the bootcamp partition on my internal drive.
Booted the system with the option (alt) key pressed down and now there was NO Windows drive to choose.
Therefore I used the Bootcamp Assistant to install Windows back onto my internal drive (including installing Bootcamp drivers in the Windows environment). This time I chose the minimum partition of 20GB for the Windows installation on the internal drive.
Booted into the new Windows on the internal drive and installed the drivers for my Thunderbolt drive.
Restarted with the option (alt) key pressed down, chose the Windows drive, but Windows Boot Manager still didn't pop up to allow me to choose the Windows installation on the external Thunderbolt drive.
Booted from the Windows DVD and chose Repair.
Restarted with the option (alt) key pressed down, chose the Windows drive, and now Windows Boot Manager finally popped up, which allowed me to choose the Windows installation on the external Thunderbolt drive again, phew!
So, I can run Windows 7 from the external Thunderbolt drive, but I have to use 20GB of my internal drive for a Windows installation I'll never use. Not the best solution, but at least I've saved 30GB of space compared to my previous Bootcamp partition - and I now have enough space to install the Windows 7 software I need on the external Thunderbolt drive...

Moving all Video to an external Drive

Was trying to get all of my videos ... some in libraries by themselves, some in iMovie, some in iPhoto into a single library ... whether under iPhoto or iMovie so that I could get that big chunk of data off my hard drive and onto an external drive.
I also have movies on another iMac, that I would like to move off of that computer and move all data onto a separate external hard drive so that I can work on movie projects on either computer just my moving the external HD from one computer to another.
Any help ... appreciated!
Thanks!

Hi
iMovie'08
Do not move or alter any folder named iMovie Projects or iMovie Events on DeskTop/Finder !
If You do - iMovie will be confused and in some cases this might end up as un-repairably.
Moving - Can/Should only be done within iMovie and in iMovie'08 only Events can be
moved. Still this is the important one as it contains all raw material and takes up most space.
In iMovie'09 and 11 - Projects also can be moved to an external hard disk.
THE EXTERNAL HARD DISK - HAS TO and should.
• HAS TO - be Mac OS Extended formatted ! ! - nothing else will work OK with VIDEO
(all mine ext.HDs are journalled - works greatly for me)
• Should be - a FireWire one as it will work much better than USB/USB2
I which that libraries would be handled same way in iPhoto - BUT They are not - For best
info ask in iPhoto forum.
Yours Bengt W

Format and partition HD without external drive - how to...

Just got a new previous gen imac and before I start saving stuff, I want to partition the drive. I'm thinking this can be done with the install disc. I'm wanting to make a partition for a Superduper Sandbox, and a scratch disc for photoshop. Is there specific directions for doing this without an external drive anywhere?
I'm not sure how important it is to have a scratch disc as I'll have 3gb ram, and I'll leave a lot of free space....any thoughts on this?

You can do it from the install disk by booting from it then instead of doing an install select a language and then, go to the utility menu and select "Disk Utility". You can then create the partitions you want, name then, and decide the size of them. After that you will have to install a new OS. Remember that doing all of this will erase the drive, so if you have any data on it you want to keep you need to get it of first.
Mac Help can guide you through this process. You could also open up the Disk Utility application which is in your utilites folder and use those application specific help files. I am making this sound complicated but really, it is not.
