How to format boothcamp partition

I have iMac (Snow leopard OS) and a friend set up a partition and installed Windows but after years I realized I don't need it.
Is there anyway to format this partition so I can use it as another drive and can be browse from Mac OS?
This is my first Mac, I don't know how to manage the partition and I don't want to format the whole computer.
Thx

Use Boot Camp Assistant. Select the menu option to remove Windows and return the drive to a single OSX partition. Do not use Disk Utility, it will mes up your drive and you will need to reinstall OSX. Make a backup of your data before you start.

External drive, how to format and partition?

Hey everybody!
I'm about to buy an external drive for my mac. I am reasonably capable on a computer, but I've never done formatting or partitioning so I have two questions:
1) I just want to check that I do not need to buy a mac-formatted drive. A little big of googling told me I could do the formatting myself with Disk Utility, just wanted to double check that that was true.
2) Once I get my external drive, what I want to do is create two partitions within that drive, one for my Time Machine backup and one for random files and movies. I'm not sure how to do that (apparently I might need to pick different formats for each in Disk Utility?) so if anybody could help out that would be brilliant.
Thanks
(if that helps, I have a MacBook Pro with a 512GB hardrive, and I want to buy a 1TB external drive)

Hi,
Here is a link that will help you set up your external drive. http://www.cnet.com/how-to/how-to-set-up-an-external-hard-drive-for-use-with-os- x/
You won't need different formats for Time Machine backups and storage space partitions. However, given the size of your hard drive, 500 gb for Time Machine may not be enough. You could buy a separate one for Time Machine, budget permitting.
Check the size of your startup disk, and if it is only 250 gb or less, then 500 gb for Time Machine may be OK, for a while. It will soon fill up, but the older backups will be erased.
Regards.

How to format one partition from existing filesysem

Hi All,
I want to install ASM on my RHEL machine. There is one disk which has been partitioned into regular filesystem as follows:

My question is, how can I format and merge a couple of partitions from these to create a volume for ASM? Is it even possible?

now /dev/hda1 can be used as ASM disk.

login to ASM and update the asm_diskstring to include this disk and run "select* from v$asm_disk" we can see this new disk as CANDIDATE Or Provisioned

Dangerous - the default partition type of a newly created partition is ext3. Which means the kernel will view that partition as a regular file system - and will attempt to mount and use it. A sysadmin will not know, looking at the type of partition, that it is not an ext file system, but in fact a raw device.
One needs to avoid this confusion - as it easily can trash your entire database's storage (diskgroup). With the only option being to restore backups that likely is out of date, or non-existent. (given the lackadaisical attitude to use a file system partition as a raw device, it is a reasonable assumption that backups are in a similar sorry state)
PS. and the question was how to use /dev/hda2 - you described removing that partition and then using /dev/hda1 (which will likely trash the root file system).

2. Open /Applications/Utilities/Disk Utility.......
3. Select the physical volume (not any partition) in the left pane.
•Note the SMART status of the drive in DU's status area, lower.left If it does not say "Verified" then the drive is failing or has failed and will need replacing.
4. Click the”Partition” tab. You will see a graphical representation of the disk in the Volume Scheme display.
5. Select the number of partition(s) from the “Volume Scheme” pop-up menu. The Volume pane at the left will change to reflect the number of partitions.
6. You can resize each partition by....

Need to format the partition for Boot Camping to NTFS. How do I do this?

So yes, I have searched online to find a way to format the partitioned to NTFS so I can Boot Camp my Mac Mini and have found nothing that I can use. Instead, all I have found are horror stories of others messing up their Macs when doing this. I want to be sure I do this as correctly as possible because I do adore my computer.
For Boot Camping, I have followed the steps and started the installation of Windows 7 but when it comes to choosing the partition it says I can't because it's not in NTFS format. Any help on this would be greatly appreciated.

Heh! Yes, it's one of those things that are simple, once you know where to look. Glad you got it figured out.
You won't quite be done once Win 7 is done installing. You'll notice that the graphics in Windows likely won't be very good, and in general running kind of slow. That's because the Windows DVD had no drivers for Mac hardware.
So you need your Snow Leopard disk. Either the first gray disk your Mac came with, it if shipped with Snow Leopard, or the retail disk you purchased.
From the Windows 7 desktop, put the Snow Leopard disk in the drive. Windows will pop up the usual message about what you want to do with an external drive. Choose "Run Setup". It will run for a while as the drivers for your Mac hardware are installed for Win 7.
Once that's done, you'll have menu icon for Apple Software Update. Run that to see if it needs to download and install any other Boot Camp updates, which would any updated Win 7 drivers for you Mac.

Use the default format and partition step to format disk0 partition 1 in multiple disks sutiation

As we know,we need to disable the default format and partition step in ts to let mdt deploy os on C and leave the other partitions stay safe when there is only one disk on pc，and the way of installing operation system is logical drive letter store in a varible.
But what if there are 2 disks on pc，and for a record the disk 0 is always the OS disk,don't need to confirmed this.How can we modify the format and partition step to format only C on disk0 under this condition?then lead the mdt to do the rest deployment
by itself.
Thanks

You are pushing up against the design limits of MDT, and the more complex and/or arbitrary the disk configuration the harder it is for MDT to perform installations.
If you want to maintain the *existing* disk configuration, and just update the OS present, then the recommended course of action is to run MDT from *within* the OS (cscript.exe
\\server\deploymentshare$\scripts\litetouch.vbs), not from WinPE. When you do this, it's called a "refresh" scenario. MDT can capture the user files via USMT, and it knows which
partitions to use, because it's launched from within the OS itself.
Disabling the default Format and Partition step has other unintended consequences.

Can someone please tell me how to format a new disk to ZFS format?

I have a Sun v240 with Solaris 10 update 8 installed on a single 73GB harddisk. Everything is working fine. I just purchased a another identical harddisk online. I plugged the disk into my v240 and ran 'devfsadm' and solaris found the new disk. I want to add this disk to my existing ZFS pool as a mirror. However, this disk was originally formatted with a UFS file system. So when I run:
zpool attach rpool c1t0d0 c1t1d0I get:
/dev/dsk/c1t1d0s0 contains a ufs filesystem.I understand the error message but I don't know how to format the disk to have a ZFS file system instead. Note that I am extremely new to Solaris, ZFS, and pretty much everything Sun - I bought this server on eBay so that I could learn more about it. It's been pretty fun so far but need some help here and there.
For some reason I can't find a single hit on Google telling me how to just simply format a disk to ZFS. Can I use the 'format' command? Maybe you don't "format" disks for ZFS? I have no idea. I might not have the right terminology. If so, apologies. Can anyone help me on this?
Thanks a lot! =D

Yes, you were right. The partitions were totally different. Here is what I saw:

Then, after resilvering completed I ran:

I also shutdown the server to the OpenBoot prompt and booted off of the new disk and it worked! Also, my bootup time to login has drastically decreased - I would say it's about half the time it was before I added the mirror disk. So I believe the server is properly reading from both disks simultaneously in order to get better bandwidth. Cool! :)
Thanks for the help!

Unable to format or partition Toshiba External HD

Hello, hoping someone can help. I had a WD external HD that I was using as my Time Machine backup for my iMac. It crapped out and since that was the second Western Digital that had died on me in 2 years I decided to go with another brand. I got a Toshiba Canvio Slim 500 GB, one that just attaches right to USB port without external A/C adapter for power.
I plugged it in, it was immediately recognized and mounted, and time machine backed up my Mac in about 45 mins. Time machine seemed to be working fine on it for about a week, then all of the sudden it wouldn't recognize it anymore. Wouldn't show up on the desktop, disk utility, nothing. I read a few articles that seemed to suggest it might be a power source issue by the drive trying to draw too much power for the USB cord to handle. So I tried to remedy that by buying a USB hub. I hooked that up, now the drive shows up in disk utility but still won't mount.
I then tried to format the disk in disk utility but that failed giving me an error message that "file system formatter failed." I then tried to partition the disk into one partition and use the GUID partition table as I have an Intel-based Mac. The partition also failed with the same error message that "file system formatter failed."
Any thoughts??? I need help. I can't return it because it has all of my hard drive contents on it now which I don't want to hand over to someone else. But I can't even figure out how to format it and erase it.
Any help would be greatly appreciated. I am running version 10.9.5 of Mavericks.

Does the hub have it's own power supply?
Test with & without the hub.
You have tried different USB ports?
You have disconnected other inessential USB devices?
Is it a custom cable? Can you try another?
I'd also try recovery mode (cmd+r at boot, select Disk Utility) to see if that works any better - that could indicate the OS is at fault.

How to format "My Passport" for Time Machine

I have purchased a 1TB Western Digital My Passport Drive (an external drive connected via USB). How should I format this drive to use it with Time Machine?
I'm running OSX 10.6.8 on an Intel iMac (hardware circa 2005). I have been using Time Machine for several years, rotating through external disks. Thie new disk will replace one of the previous disks which has failed. I have forgotten how I formatted the previous disks. I'm primarily interested in whther to use HFS or whatnot. As to partitioning, the format will just be one partition for the whole disk.
I'm going to see if I can figure this out using Disk Utility, but in the mean time, does anyone have recommendations?
Thanks in advance,
Frank

Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select the WD Passport drive (entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

HT1338 how to format my hard disk

how to format my hard disk ....my mac book came with no cds

You do this either with a Mountain Lion install disc or drive, which you have to make yourself, or from the Recovery System. For the Recovery System, you reboot while holding down command-R. This boots from a (hidden) recovery partition that is on your hard drive; then you access Disk Utility and do your formatting that way. The Recovery system can do a new install of Mountain Lion from the internet from apple once you have reformatted your drive. Or you can make a ML installer disk from the installer files that you download for future reference.
Here's a page about Recovery mode: OS X: About OS X Recovery
and here's how to make your own ML installer disk: How to Burn OS X Mountain Lion to a DVD or USB Flash Drive..
BTW, you could have figured out all this yourself with a google search.

HT4522 Sounds fine but how do I add partitions in air port utility

Sounds fine but how do I add partitions in air port utility

It is possible to partition the drive, but you have to physically pull the hard drive from the Time Capsule and place it in a separate enclosure for the formatting operation, then reinstall the drive again back in the Time Capsule.
Unfortunately, in addition to a lot of work, this will void the warranty on the Time Capsule.
It is possible to create one or more disk images on the Time Capsule using Disk Utility.
While a disk image is not technically a "partition" in the normal sense, it will allow you to specify and reserve a given amount of space on the drive for the image or images that you create.

How to format external HD and install software on it? Help, please?

That's the theory. Note that you'll wipe the external drive in the process, so if there's anything you want on it, get it copied elsewhere first. It’s always wise to back up any important stuff on your MacBook of course before doing anything like this (but not to the drive you’re about to use!)
With the drive connected, open Disk Utility, highlight the external drive in the sidebar (that's the drive itself, usually listed by the manufacturer's name and the size of the drive). Select 'partition' in the tab bar, ensure the drop-down on the right is set to 'Mac OS Extended (journaled)', give the partition a name in the box above that (like 'ext HD' or whatever). Click on the 'options' button below the diagram and select 'GUID Partition Table' (very important - it won't boot SL with any other setting). then click the 'apply' button.
Once that's done, close DU and insert the 10.6 install DVD in the MacBook (or whatever the Mac is). After the licence agreement there’ll be a picture of Macintosh HD, but underneath should be a button saying ‘show all disks’. click that and select the external drive, then click install and follow the instructions.
Note that if you do this with the grey install disk that came with the computer, you will only be able to boot that computer with it, as it’s model specific. If the install DVD is a black retail one, it should theoreticaly boot any Mac (but note the licence conditions).
Once the install is complete, boot from the external HD by either selecting it under ‘startup disk’ in Sys Prefs, or by holding down the alt key during restart and selecting the drive from that screen. You can then install any progs you want and try them out from there. (don’t forget to reset the startup disk when you want to reboot from the MacBook).
If you don’t have a DVD, or you want a duplicate of your existing system, go with the clone idea, using CCC (not because it’s better than SuperDuper, but because it’s free if you don’t mind putting up with a few ads while it’s working!)
Hope that does the trick for you.

How much should I partition for Time Machine/Backup?

Hi all,
I upgraded my PB G4 HD to a 160GB recently and have just purchased a 1TB External HD. How much should I partition in the external to be used for Time Machine backup purposes of my internal HD? Will the same size suffice, or should I allocate more?
Also, I was thinking of formatting the drive so that it's both Windows and OS X friendly, but that means formatting it to MS-DOS something (I was just reading about it in another thread), will that cause any issues for the partition for Time Machine that I created? Thanks.

That's not practical. If you want to use the hard drive on a Windows machin while still being useful for Time Machine you should use MacDrive.

I would make the partition at least twice the size of the internal drive. Preferably, you would want 50 GB for a Leopard install that includes just the base operating system so you can boot off the 50 GB to recover your Time Machine data if your Leopard installer disc ever becomes unusable.
Also since you have a Powerbook, your 1 TB hard drive should be Firewire. USB will not boot Powerbooks. If it is USB only, you can remove the external hard drive case and replace it with one compatible with the drive inside that case from http://www.macsales.com/ that has Firewire.

Accidentally re formatted PC partitioned hard drive. now can't use.

Upgraded to Leopard. Installed boot camp. Runs PC side well. Accidentally re formatted PC partitioned internal hard drive (thought I was formatting an external back up hard drive). Now Windows XP gone and re installed Mac side too small to back up. Would like to combine hard drives to original Mac mini and start over. How do I do that? (I have Mac backed up on external drive from Time Machine and Windows as well as I can).

Run the Mac OS X install DVD, go to disk utility and delete the PC partition. Then Resize the existing Partition to fill the free space.
You don't have to re-install OS X if you don't want to, Leopard's disk utility has non-destructive resizing.
You can also try to perform this action from within the OS, although I've had a few problems with resizing before and find it works best straight off the DVD.
Good Luck!
