Partition Mac OS X El Capitan hard disk drive

When you sit down to do a partition of your hard drive, you are basically separating your storage space into different entities. Since physically, your hard drive is just one, it can be counted as a sort of organizational work for your computer. Partitioning your hard drive is good for your system since it allows you to keep a set of files separately from others. Partitioning is a useful tool for every computer user and it isn’t a difficult task either.

Partitioning in Mac can be done by Disk Utility which is an application that comes along with Mac operating system. What makes Disk utility the best choice is not just that it is free but also owing to a graphical interface that makes it convenient for the user, straightforward and pretty easy to use. Moreover the Disk Utility version present with OS 10.5 brings us many convenient features such as adding, deleting and resizing hard drive partitions without the need for erase the hard drive first. Addition of Disk Utility to El Capitan makes it the all purpose application in order to manage hard drives on Mac.

When you partition a storage device, it divides it into individual partitions which later occur as volumes in the system. If you need to do the partition in order to install multiple operation system, you would require partitioning the disk. For this, you can use Boot Camp Assistant if you are partitioning your internal disk for installing Windows.

How to add volume without deleting existing data

  • Open Disk Utility. Go to sidebar, select the ‘device’ and click on the ‘Partition Button’.
  • Click ‘Add’. This will allow the Disk Utility to create 2 volumes. It will let one of the volumes retain all the data while the other would be empty. (In case the original volume contains less than half of the data, then disk utility partitions the drive into 2 volumes of equal data. However, in case the original volume has too much data, then disk utility partitions in such a way that one of the volume is smaller than the other.)
  • In the pie chart, click each of the volume and rename it.
  • You can increase or decrease the size using the divider or simply enter it.
  • Click the format pop menu to select the format for each volume.
  • Click ‘apply’. In case you want to view the step by step process, click ‘show details’.
  • After the task if finished, click ‘Done’.

Once this is done, you can see the newly created volumes both on the disk utility sidebar as well as the finder sidebar.

How to enlarge volume

This option can be used when you have multiple volumes and you find that one of the volumes is running out of space. You can increase the storage of that particular volume without losing data. To enlarge, delete the volume that comes after it on the device. Now use the freed space to move and point of the volume that you want to enlarge.

  • Go to ‘sidebar’. Choose the volume you want to enlarge. Click on ‘Partition’.
  • Select the volume you want to remove from the pie chart on the left side.
  • Click ‘apply’. This will allow that particular volume to be deleted and add that remaining volume to the previous volume.
  • Click ‘done’.

Erasing and repartitioning your device

Use this when you wish to erase all volumes and create new ones.

  • Go to ‘sidebar’. Choose the volume you want to erase. Click on ‘erase’. The device that contains your start-up volume won’t be deleted.
  • Rename the Initial volume.
  • Choose format for the initial partition from the Map pop-up menu. Use an 11 character or less, name for MS-DOS and ExFAT partitions.
  • Click Erase> Done

Partitioning your hard drive may cause loss of data. In case, you don’t have a back up there may be chances that you end up losing all of your data. That is why, creating a backup should be your first step before doing the partitioning, for those who have lost data or partitions in their Mac can use a third party software in order to attempt recovery of your data.

Partition external hard drive for Mac Time Machine & Windows

Many Mac users have this obvious question as to “How to partition their external hard disk drive” so that it can be used for Mac’s Time Machine backup purpose as well as on NTFS formatted Windows system. Partitioning the external hard drive with HFS and NTFS format have below benefits:

  • The HFS formatted partition of the external hard drive can be used to take Mac backup through Time Machine application. To enable the Time Machine backups, the external hard drive must be formatted with HFS file system.
  • The NTFS formatted partition of the same external hard drive will easily let you connect the drive to Windows system and use it for file transfers. Either, format the same partition with FAT file system that will allow users to use the partition of the external hard drive on both Mac & Windows.

How to partition external hard drive with HFS through Disk Utility:

1. Connect external hard drive to Mac OS X

2. Press Command+Spacebar to bring Spotlight. Type Disk Utility and click on the application to launch Disk Utility

3. Select external media and click on ERASE tab

4. Select Format as – Mac OS Extended (Journaled) and Name the hard drive

5. Click Erase and again confirm Erase to proceed

1

6. After process finishes successfully, go to Partition tab. You will see the external hard drive has been formatted with HFS file system. Though, the external hard drive has only 1 partition. Unfortunately, Disk Utility won’t create another partition with NTFS file system. Now, we take the help of Stellar Partition Manager software in order to create a partition with NTFS file system.

7. Below is the screenshot of external hard drive that was formatted with HFS file system through Disk Utility. As you can see there is hardly any free spaces left to create another partition. But no worries, the software will resize the HFS partition and make room for NTFS partition.

2

8. Resizing of HFS partition done successfully. Now, enough free spaces is available for another partition.

3

9. From software top menu bar, click ADD. Give Volume Name and Partition Type. The partition type in our case is NTFS. Click the ‘Tick’ button to proceed.

4

10. As shown above, Windows partition with NTFS file system has been created. However, the size of the NTFS partition is too small. Let’s resize the partition to a suitable size. You can allot all the available free spaces to the Windows 7 partition.

5

11. Resizing of Windows partition done successfully. From the software top menu, Click START button to save all changes. Process is underway as shown below:

6

Once done, the drive will be consists of 2 partitions – HFS and NTFS. User can use these partitions as per their requirements. User can also choose to format the partition with FAT/EXFAT in place of NTFS. However, unlike FAT, NTFS and HFS partitions, EXFAT partition can’t be resized.

How to Partition Mac Hard Drive using Disk Utility or Partition Manager Software

Many of you have different types of data stored on your Mac OS X. Haven’t you? For example, your personal collection of photos, videos, movies and many other important things. Now, main question is how do you able to manage all these important things altogether? Don’t you get confused when looking for a specific file in your system? Well, each person answers these questions quite differently from others. Do you know why? Actually, this is just because of the data storage scheme pre-exist on the HD. Well, no matter whichever scheme they follow, it would be best if the partition of your Mac OS X hard drive store different types of files on different volumes.

When it comes to partitioning a HD, Mac OS X leads the count because it facilitates partitioning its hard-drive into 16 different partitions. However, disk partitioning on Mac system is not as easier as it appears on Windows.

Besides, delving deep helps you make out that apart from making data storage better and access efficient, HD partitioning keeps the user data secure from each threat to the boot volume. Suppose, all of your data is stored on the Mac boot volume along with the main system files and your Mac OS X fails to boot all of a sudden, then you would no longer be able to regain your data, even if you reinstall your OS X. This is because reinstalling Mac OS X would overwrite the data already existing on your hard-drive. In contrast to this, partitioning your Mac hard-drive allows you save all of your important data separate from the system files, which keeps it protected from each threat to the boot volume.

Additionally, you can install multiple operating systems (i.e. Mac as well as Windows) on separate partitions of your Mac drive, which keep your Mac data accessible even if your Mac system fails to boot from the primary boot volume. In order to perform all partitioning related tasks, Mac partitioning tool is the major requirement. However, you can also use Disk Utility as the default partition manager Mac OS to perform these tasks.

Disk Utility as the Mac partition manager

Mac OS X has an inbuilt disk management tool – i.e., Disk Utility, which is easily able to format as well as partition the Mac HD. Therefore, no matter whether you are going to partition an external or internal hard drive, steps to partition Mac drive will not differ. To know how, you need to take the below mentioned steps:

(1) Formatting Mac Drive

You cannot use a complete brand new hard-drive on a system until you make it usable. This process is termed as formatting the HD. In order to make a hard-drive usable on Mac OS X, first you need to format it as Mac OS Extended (Journaled). For this, first you have to hook this hard drive to your Mac with a USB cable. After that, you need to follow these steps:

As you attach a brand new drive to your Mac system, Disk Insertion message pops up. On this message box, click initialize button to launch Disk Utility.

Step 1: In the left pane of Disk Utility, highlight this hard-drive and then simultaneously go to the Erase tab at the right.
Step 2: From the Format menu, choose Mac OS Extended.
Step 3: In the Name field, specify a name for this drive.
Step 4: In the end, click Erase button.

(2) Partitioning Mac Hard- Drive

Once disk formatting process is finished, a message will pop up to notify the same. After that, you can proceed to partition it. For this, take the following steps:

Step 1: With the external drive selected at the left, go to the Partition tab at the right.
Step 2: Herein, click Options button and choose GUID Partition Table (on your Intel-based Mac) in the window that opens.

(Important: Choosing GUID Partition Table for a drive enables Intel-based Macs boot from it.)

Step 3: After that, click OK button.
Step 4: Click the Volume Scheme drop-down menu and choose the number of partitions to create on this drive.

(The number of partitions you choose in Volume Scheme menu will slice this drive into its equal number of partitions.)

Step 5: now, select a partition in the graphical view and give a name, choose a Format, and type the Size for this beneath the Volume Information area.
Step 6: Likewise, format other partitions as in Step 5.
Step 7: When finished, click Apply button.

Use Mac Partition Manager Software:-

As you know, Mac OS X facilitates partitioning its hard drive both during and after its installation. You may find disk partitioning task a bit difficult, but you can perform it easily if you have a reliable partition manager Mac OS application.

Step 1: Install Mac partition manager software.
Step 2: Now, Go to the Applications and launch this app.
Step 3: Select the disk that your need to partition and select the total number of partitions to create.
Step 4: After this drive is partitioned, select one partition and format it with Mac file system.
Step 5: Similarly, format the other partitions as well.
Step 7: Finally, save the modification done so far.

Once finished, you can use these volumes for both saving data and installing Mac OS X. You can install Mac OS X on any of the partitions created as above. However, in case you need to install Windows, you need to format the selected volume as MS-DOS (FAT).
Final Conclusion:-As for now, you have made out how to perform partitioning tasks using Disk Utility as well as a partition manager software like Stellar Partition Manager. Therefore, based on your convenience, you can use the one you find best as per your suitability.

Why partitioning Mac hard drive is a good idea

Mac Hard drive partitioning – of course you’ve heard of it, but don’t really understand how to do it or even why. Your colleague has his personal Mac’s HDD partitioned and he has been doing that ever since he got his first PC. On discussing with him, he fills you in on the reasons that he thinks make it a good option. You’re intrigued and even consider doing it yourself. But when you read up about it, you find out that first you’ll need to erase your entire hard drive’s contents (there are software available that let you partition without having to erase it), it can lead to wastage of space and even adversely affect your hard drive’s performance. You’re back to square one.

If you find yourself stuck in one of such situations quite often and can’t decided whether to partition Mac or not, we’ve got some more food for thought for you. Relax! We won’t confuse you further; we’re here to help. Partitioning your Mac hard drive is actually a good idea and we can give you 5 good reasons why. Check them out and hopefully we’ll gear you up to take the plunge.

What does partitioning Mac hard drive mean?

Let’s just go through this quickly to clear any doubts that you may have. When you purchase a brand new Mac, it comes with one startup drive that could be a traditional platter based hard disk drive (HDD) or in a few cases, a solid-state disk (SSD). Named “Macintosh HDD” by default, this is where all your system files reside and where you can store additional data and continue to work from. While this arrangement is fine for most people, to reap some additional benefits, you can split up the storage space on the disk into sections and dedicate each one to a unique purpose. Doing so also helps keep your Mac more organized and keep your data structured. The sections that you create on the disk to logically divide the total space on it are called partitions and this process can be applied to any internal or external disk.

why-partition-mac-drive

What do I gain out of partitioning?

A lot actually! As already mentioned, a cleaner, more organized Mac definitely means a healthier Mac. Keeping the data structured means better protecting it from vulnerabilities. The more isolated crucial or a particular kind of data is, the better in some cases.

Moreover, consider the following solid advantages of Mac hard drive partitioning:

It can help you use multiple operating systems on the Mac

This is the most common reason most people partition their Macs – to use boot camp. If you wish to use both Windows and Mac on one machine, a dedicated boot camp partition allows you to do so easily. Using Boot Camp Assistant (built into OS X 10.5 Leopard and later versions), you can create a special partition on your Mac that’s dedicated to your Windows installation. However, to use this utility you’ll have to make sure there are only 2 partitions on your hard disk, one for OS X and one for Windows. Boot Camp Assistant doesn’t work on already partitioned disks. There are other software available (like Open Disk Utility) that help you create more than 2 partitions on your Mac hard drive in case you wish to go further and create a third partition for Linux.

It enables you to switch between multiple OS X versions

If you have an Intel-based iMac (early model) that’s capable of running multiple OS X versions like Leopard, or Snow Leopard, you can create multiple partitions on your hard drive and dedicate one to each. That way you can use more than one OS X versions on one Mac. To switch between them (say, for testing purposes or to use some specific app or software that runs on a particular OS X version), just open the System Preferences -> Startup Disk pane, select the partition you want and then Restart the Mac. You’ll boot to the selected OS.

It allows sharing the iPhoto library between 2 or more user accounts on the same Mac

As per Apple’s suggestion, if you wish to share one iPhoto library between 2 or more user accounts on the same Mac, one way to do that is to move it to a volume where ownership is ignored. Of course, the other volume shouldn’t be the startup volume although it could be an external disk or another partition of your hard disk.

It helps repair disk problems

Having a second partition is also justified when it comes to running a repair program like Disk Utility from a volume other than the damaged one. To run such a repair program on a volume that develops errors, you need another volume that could be an external hard disk, a bootable DVD or another partition that includes a bootable copy of OS X and some repair utilities. Such a volume can serve as the boot-up volume in case the original startup volume is in a crisis.

It enables better backup management

When it comes to backing up, what better place to store it than another partition on your internal hard disk. Well, actually the best place to store it would be in an external disk and at a different location but you could have at least one copy of the backup within immediate reach if your startup volume fails. Plus a partitioned hard drive also gives you an option to store one copy of the bootable volume on one partition and use the other for versioned backups.

To sum it up

Convinced yet? We’re hoping you are! Mac hard drive partitioning could turn out to be great for you if you keep all the basics in mind and have backups of all your data. Data stored on different partitions is more secure, more organized and better managed.

How to add More Space in one Mac Volume by Deleting Other

Even though disk partitioning is not a major concern on Mac, it becomes quite difficult to partition disk when it contains important data. In fact, the task is termed as repartitioning Mac drive.

Partitioning Mac drive, though, is not as easy as that of Windows’. However, it is yet recommended because it facilitates storing different types of data separately. Besides, it facilitates installing multiple operating systems (i.e. Mac as well as Windows) on separate partitions of your Mac drive. Well, following are its additional advantages:

Since partitioning your Mac drive makes multiple partitions available, by storing different types of data (viz. movies, pictures, songs, apps, and professional documents) on separate partitions, you make data storage efficient. Besides, it makes looking for a specific file quite easier. Suppose, you are looking for a particular audio file, though you can search it in the Finder, easy and efficient storage format helps you find it quickly.

Additionally, partitioning your Mac drive makes your data quite secure, as it keeps your data apart from the boot volume. Suppose, if your Mac drive has only one partition (i.e. the boot volume, Macintosh HD), it is evident that all your data is stored on the boot volume along with the system files. In this case, as long as your Mac is running, you can easily access your data. However, you would no longer be able to access your data in case your Mac fails to boot. In contrast, having multiple partitions allows you store your data separate from the boot volume, thereby avoiding all threats to your data.

As an additional feature, having multiple partitions on your Mac drive allows you multi boot your Mac system. Suppose, your Mac drive has multiple partitions, one of which you can use to install another operating system (i.e. Windows or Mac) on it. In case your Mac system fails to boot from the primary partition, you can boot it from the secondary boot volume. In this way, it makes your data accessible. Meanwhile, you can repair the primary boot volume or even reinstall Mac OS X on it.

Partitioning Mac drive – Disk Utility as the Mac partition manager

As mentioned earlier, data storage on a hard drive having multiple partitions is much better and more efficient as compared to a hard drive having only a single partition. Well, in order to help you out, Mac OS X allows partitioning its hard drive into a number of volumes. Besides, in case you need to delete Mac partition, you can go for it anytime. However, have you tried partitioning your Mac drive on your own? Well, if not yet, then you may not find yourself confident enough to delete the required partition.

You may wonder that why one would need to delete any of his Mac partitions, but the need actually arises. Suppose, your Mac has 5 partitions (including the boot partition) having data stored on them. You suddenly notice that the volume containing your personal collection of movies is overfilled. Now, since you need to enlarge this volume, you can either shrink or delete any of the secondary volumes. For this, you need a professional Mac partition manager or you can do it using Disk Utility as well.

Case I: Shrinking Mac volume to enlarge the overfilled volume

Disk Utility is the Mac inbuilt disk management tool, which allows you format, partition, erase, image, clone, and repair Mac disk easily. Well, in order to enlarge one Mac volume, you need to have required amount of free space, which you need to trim from other secondary volumes. In this regard, following are the steps you need to take:

Step1: Launch Disk Utility (follow Applications > Utilities > Disk Utility).

Step2: In the left pane of Disk Utility, select your Mac drive and go to the Partitions tab at the right.

(In the graphical view of your Mac drive, you see that each volume contains two colors, where one is white and other is blue. As per the color scheme, the blue color in the partition denoted the data, whereas the white color denoted the free space.)

Step3: Now, select the volume that you wish to trim the free space from.

Step4: Hold the volume from its bottom-right corner and drag it upwards to shrink it.

Step5: Likewise, you can shrink other volumes if you need more free space.

Step6: When required amount of free space is available, hold the target volume from it bottom-right corner and drag it downwards to enlarge it.

Step7: Finally, click Apply button

 

Case II: Deleting a volume to enlarge the overfilled volume

Well, you can also delete one or more Mac volumes if they are empty or contain useless data. Following are the steps that you need to take to delete Mac volume:

Step1: Follow the Step1 and Step2 as discussed above.

Step2: In the graphical view of your Mac drive, select the volume that you want to delete

(Make sure you select the correct volume, as deleting the wrong volume will lead to data loss.)

Step3: With the target volume selected, click the delete (-) button that is given beneath the graphical view of your Mac drive.

(Deleting this volume create the free space on your Mac drive.)

Step4: Now, follow the Step6 and Step7 as discussed in the previous section.

Step5: Exit Disk Utility.

Well, apart from Disk Utility, you can also use a commercial Mac partition manager to perform these tasks automatically. Besides, make sure the one you choose is reliable.

Mac Partition Manager vs Disk utility Mac

Mac is equipped with an in-built partition manager and disk management tool named Disk Utility. It facilitates a wide verity of features to perform multiple disk and disk volume-related tasks, such as backup, verify disk integrity, repair, formatting, partitioning, erasing, and cloning disks, etc. Most of the users use this module on Mac in order to complete multiple actions. However, there are some other tools too that can help to manage the Mac efficiently and also include some additional modules that disk utility doesn’t equip with.

Stellar Partition Manager is included with all the features of disk utility with some additional ones that make it better and preferred partition manager software. Let’s discuss about both the partition managers and compare both of them on a Mac OS X.

Drive Partition with Disk Utility

Disk utility is a very efficient and easy to use module on OS X, which reduces the complexity of disk management. You can easily create, remove, repartition or resize the Mac drives whenever needed, while keeping the data safe. However, in order to perform the resizing process on a partition with disk utility, you need to empty the next volume in the disk.

At times, you need to enlarge your boot volume if it is running out of space. You can do it with Disk Utility. To initiate the process, you need to delete the partition that comes next to the boot volume or any other partition on the disk and then move the partition’s end point into the freed space. However, disk utility doesn’t allow you to enlarge the last partition on a disk. Resizing the boot volumes with Disk Utility is not always a good idea as if something went wrong, then it may result data loss. Therefore, make sure that you have backed up complete hard drive using Time Machine or any other backup service you prefer before you begin.

This volume enlargement process could be more complex as Disk Utility does not list the free space along with other partitions under the Partition tab. After successful enlargement of required boot drive, if the enlarged partition doesn’t use the complete space from the deleted volume, you can use the remained space to create a new partition in the unused space.

Resize with Stellar Partition Manager

Stellar Partition Manager provides you a reliable way to manage your partitions without involving any risk of data loss. It will reduce all the complexities and make it easy for you to manage hard drive partitioning on Mac. This professional partition manager software lists all the available drives attached to the concerned Mac machine, you can select any drive from the list and manage its respective volumes with powerful modules. When you run the Stellar Partition Manager, you will be able to see the graphical structure of the selected drive with free and occupied spaces in the middle pane of the main window, where the right pane will show all the drive information.

The middle pane of the software is used to choose a volume from its bottom right corner, and drag the space either upwards or downwards to shrink and enlarge the size respectively.

Additionally, Stellar Partition Manager also includes multiple other powerful modules, such as deleting, hiding, formatting, and revealing, and rolling back the changes done in previous step. The rollback feature allows you to revert to a previous state of a volume, in case you have performed it accidentally. In addition, this tool also allows you to protect or hide your important files or partitions from anyone, who you do not want to see them.

Conclusion

Stellar Partition Manager and Disk Utility, both are equipped with multiple common features like formatting, partition, resizing, and deleting Mac volumes, which make them equally well, but still Stellar Partition Manager has some additional features like hiding/revealing a volume for data security, which makes it a better tool than Disk Utility.

How to Resolve POSIX Error during partitioning & Formatting USB drive in Mac?

Usually, Mac operations do not create issues unless there is some unavoidable circumstances do not appear. People who use Mac systems in their daily life routine, might have faced different unknown errors while partitioning or formatting Mac hard drive, external drive or a USB flash media. Here, in this article you will get to know about such errors that you may come across while performing different operation in Mac hard drives using Disk Utility.

Posix

Image Source: CNET

For Example, if you are trying to partitionand format various Mac based USB hard drives, and suddenly you have encountered an error message ‘Disk Erase failed with the error: POSIX reports: The operation couldn’t be completed. Cannot allocate memory‘ and your work stopped in mid. Basically such type of problem is not common in all types of disks. These errors are more specific for the USB chipsets and firmware versions or settings in certain drive enclosures. Except this, there could be multiple errors that your Mac system could have been affected by concerning POSIX error. Most of the people think that this error might have resolved by replacing drives, swapping or wiping drives, replacing memory modules, installing OS, etc. and get confused again when the same issue replicates.

Solution

Whenever you encounter a POSIX error message while working over Disk Utility, the first thing you should do is to check whether your system boots up or not. If yes, then verify whether it copies and pastes files over System Disk. However, if not, then try to boot up your system from external OS drive and when your internal system drive is mounted, try the same process of coping and pasting again for your internal drive.

In case you are unable to write on disk or disk taking long time to boot, then there is a high possibility that the actual problem is specifically for USB connections such as: the SATA cable or SATA cable assembly in the portables.

Therefore, check USB connections to troubleshoot such issues, specifically those ones, which are connected with drives and change SATA (assembly) cable connections before concluding that the system Drive is failed. Now, check whether they are able to properly format through those connections. If by using another alternative connection, your drive starts working normally and you are able to format it, it means that the problem is with Disk Utility itself. The disk utility is not able to manage specific partition setups over the USB connection.

If your problem is to overcome the default partition scheme or formatting issues over USB connections while using Disk Utility, try to use terminal commands as an alternatives option, where initially you have to format the drive, after that it will become accessible via Disk Utility again.

You have to find out the disk identifier for the attached USB drive before running these commands. In order to do this, run Disk Utility and choose the drive device itself. Now, select the ‘info’ button and note the name of the ‘Disk Identifier’ field.

‘diskutil’ command

Enter the ‘diskutil’ command in the Terminal to format the drive. Now, replace the ‘NAME’ with your desired name of the drive, and ‘IDENTIFIER’ with the drive’s ID found in Disk Utility:

diskutil eraseVolume HFS+ NAME IDENTIFIER

‘fdisk’ command

This is an alternative command to the “diskutil” command is ‘fdisk’, which is used to create partitions and set up the drive. Like the diskutil command, here also you need to replace the IDENTIFIER portion with the ID found in Disk Utility:

fdisk -a hfs /dev/IDENTIFIER

With the use of these above mentioned commands try to manage the drive again in the Disk Utility.
