What Is an External Hard Drive for Mac?

Most people who have used computers extensively know what hard drivesare. They are devices, usually built-in to the system, that are used for storing large amounts of data. All software on a computer, including the operating system, is installed and stored on the internal hard drive. Many computers, including Macs, tend to come with small internal hard drives or solid state drives that will quickly become full, especially with heavy computer users, and the need for expanding the internal storage comes into play.

One of the best and easiest ways of increasing the storage capacity of your Mac is by connecting an external hard drive. External hard drives are generally the same as internal drives, in that they are a physical drive that stores data on spinning metal plates. In the case of an external hard drive, the drive itself is stored inside an enclosure that includes the proper ports for connecting it to your Mac. Most external hard drives connect to a Mac either through the USB port, or through the Mac's Thunderbolt port, and thus will likely come with the appropriate cable.

If you are looking for an external hard drive to connect to a Windows PC instead of to a Mac, check our reviews of five of the best external hard drives for safe data storage.

What Features to Compare

Most external hard drives that are available on the market are actually compatible with a Mac, even those that are labeled as being for Windows PCs only. A Mac is able to interface with and read data that is stored on an external hard drive that has been formatted for PC. However, Many of the tools that are included with the external hard drive may not be compatible with the Mac, which can be a problem if you wish to utilize those tools. For finding the best type of external hard drive to connect to your Mac, there are a few things that you will want to pay attention to before purchasing an external hard drive.

Capacity

The total capacity of an external hard drive is going to be important, especially for those who work with lots of data. The larger a hard drive is, the more data that can be stored on it, so those who have large data workloads will want to buy the highest capacity hard drive possible. Thankfully, many of the hard drives featured in these reviews come in multiple capacities, so there should be plenty of choice for both low and high capacity hard drives.

Operating System Support

Many external hard drives will show that they are compatible with both PCs and Macs, while others will show that they are compatible only with one or the other. As stated above, virtually any external hard drive will work with a Mac, including those labeled as being for PCs only. However, finding a drive that lists itself as being compatible with both will be ideal, especially if the hard drive is going to be shared between a Mac and PC computer. A Mac is able to read PC formatted hard drives, but a Windows PC can't read a Mac formatted drive, so if you need to share the drive between both types of systems, get one that is listed as being compatible with both.

Interface

The interface is what the external hard drive will use to connect to your Mac. The two main interfaces you will find are USB and Thunderbolt. If you are using an older Mac that does not have a Thunderbolt port, then you will want a hard drive that connects through USB. Likewise, if you need to share the drive with a Windows PC, USB support for the drive will be a necessity.

Backup Support

Many external hard drives will come with backup software that is ready to use, whereas others will come with no software at all. Almost any external hard drive is going to be compatible with Apple's Time Machine backup software, but if you prefer to use different backup software, you might want to opt for an external hard drive that comes with its own backup software solution.

Although most external hard drives should work fine with your Mac, keeping the above characteristics in mind when looking for the best external hard drive for Mac will ensure that you make the best choice possible.

Connecting an External Hard Drive to Mac

Best Backup Drive For Mac

Those who are either computer novices or who spend much more time doing productive work on a computer than in getting to know the ins and outs of it may be unsure of what needs to be done to connect an external hard drive. Thankfully, it is a relatively simple procedure, especially with a Mac. Most hard drives that advertise themselves as being Mac compatible will often come pre-formatted with a compatible file system, usually either HFS+ or NTFS (Windows file system). It should be noted, however, that Macs can only read data from NTFS formatted hard drives, not write to them. Some other hard drives may come without being formatted, although this is actually rare. For those that are already formatted, simply plugging the drive into the USB or Thunderbolt port should be enough. Once the drive is connected, the Mac should automatically recognize the drive and place an icon for it on the desktop.

Formatting an External Hard Drive

In the case of getting an external hard drive that is either unformatted, or pre-formatted for Windows as NTFS, the formatting procedure is still very simple. When the drive is connected to the Mac, it may or may not show an icon on the desktop. Drives that come pre-formatted as NTFS will display the icon, but usually give you a warning that the drive is read-only. If this is the case, or the drive is not appearing on the desktop, then you will need to open Disk Utility by clicking on the Go menu at the top, select Utilities, and then select Disk Utility.

In the Disk Utility window, you should see the external hard drive listed there, and labeled as an external drive. Select the drive, and then select Partition near the top. Here you can set a new name for the volume, choose the size of the partition up to the maximum possible size, and also select the file system to use for the drive. If you are needing to read and write data to and from the hard drive, then you want to format the drive as 'OS X Extended (Journaled)'. Once the drive has finished partitioning and formatting, it should be ready to go, which will be indicated by the drive icon appearing on the desktop.

For those who need further assistance with connecting and formatting a new external hard drive for Mac, this page has more detailed instructions on this process.

Backup Data to New External Hard Drive

Some of those who purchased a new external hard drive for Mac may want to use the drive for backup purposes rather than for extending their total storage capacity. If you are wanting to use the drive to make backups of your important data, this can easily be done through Apple's Time Machine utility. When an external hard drive is first connected to the Mac, you may see a pop-up asking you how you want to use the new drive. On this pop-up, clicking on 'Use as Backup Disk' will automatically prepare the drive to be used for backups. If you want the backups to be password protected, then selecting the 'Encrypt Backup Disk' checkbox will ensure that only you have access to the backup disk.
