Why partition an external hard drive mac

Instead of forcing you to buy a separate system for each. Sometimes, you might require accessibility of both the operating systems: Mac and Windows.

In such cases, having two separate system is not a smart option when you can easily both on Mac using BootCamp Assistant. Start-Up Disk Errors can happen anytime, anywhere and with anyone. To resolve start-up volume disk errors, the solution is to run a repair program from another volume a bootable DVD or external hard drive. But, if you already have a partition on your main disk that includes a repair utility and a bootable copy of macOS, the repair job will be quite easy.

Sometimes, you might require sharing Photo Library between more than one user accounts. Obviously, you cannot do it on the main startup volume. But, if you have separate partitions on the internal disk, you can do it as those partitions does not have ownership.

Apple comes with an inbuilt backup feature—Time Machine to facilitate this need. In case, you have more than one partition on your disk, you can easily backup over there. This will not only offer you ease and convenience in backing up but also helps you to reduce the unnecessary cost of buying a different hard drive.

In present digitized era, system failure is quite common. In case you have a single partition to store your data and system files and a system failure happen then, as consequence everything will vanish.

But, on contrast, if you have separate partitions for both, then certainly you will not lose your data as system files and other data are separate. It is quite logical to say that, a drive works in complete synchronization when it has fewer data in comparison when it has large chunks. Page content loaded.

To do that all you do is drag up the partition in the partition window from the bottom right hand corner. You can still use the Time Machine partition to store other files. Time Machine stores its backups in a folder called Backups. So the rest of the drive can be used for whatever you like. I do have mine partitioned so I could also clone my boot drive to that other partition. I also have a complete copy of all the data that I have on my second physical drive in my Mac on that same TM partitoin on the external.

I have no problems keeping TM backups and that other data on that one partition. After reading your replies, I'm wondering if the info. I was given today by an Apple emp was incorrect, but let me see what y'all think:. My new MacBook Pro will be used for the same, but expanding it's use to include my business marketing, billing and the like. I don't need all the old files off either computer, but would like the option of having some I may need on a hard drive in case I need to refer to them.

SO, I bought a 1. Given the size and how I'm using it, I would think 1. The Mac emp told me today that this is not how the hard drives work and that I would be better off to use a small, maybe hard drive to store the old files from my PPCs and use the 1. Thanks so much for your insight and confirming what made sense to me as a convenient way of backing up my new laptop whilst storing items I needed from my old laptop.

What is your advice to this? I am really hoping to reformat it to exFAT format. If an external hard drive partition has a cluster size of 16 kilobytes, then even an empty file that has been saved will be that size. The larger a partition is, the larger the cluster size will be; creating two or more partitions on a large-capacity hard drive reduces the cluster size of each partition and helps you make better use of your storage space.

Whether because of work requirements, software compatibility issues or simply because the user is a computer enthusiast, some people with high-capacity hard drives choose to install multiple operating systems so that they can use a different OS at different times. Each operating system needs to be installed on a different partition in order to function properly, so the external hard drive needs to have at least one partition for each operating system installed.

Some computer users who partition external hard drives do so because it aids their file organization. They might choose to have one partition for documents or music, another for installed programs and a third for storing drivers or other files. This cuts down on time spent searching for specific files, as each partition has only specific file types on it.
