How do I find my internal hard drive on my Mac?

Finding your internal hard drive on a Mac is easy once you know where to look. The hard drive is where all your files, applications, and operating system are stored on your Mac. Knowing how to locate it can be useful for a variety of reasons, from checking storage space to troubleshooting problems.

What is an internal hard drive?

An internal hard drive is a storage device located inside your computer. It is a physical component that reads and writes data through mechanical spinning platters or flash memory. The hard drive is what stores all the data on your Mac, including:

  • Operating system files like macOS
  • Applications and software
  • Documents, music, photos, videos, and other personal files
  • System settings and preferences

Hard drives come in two main types – traditional hard disk drives (HDD) and solid state drives (SSD). HDDs have physical moving parts that access data, while SSDs are faster solid state memory with no moving parts. Most modern Macs come with fast SSDs, while older Macs likely have HDDs.

Why would I need to find my internal hard drive?

There are several reasons you may want or need to locate your Mac’s internal hard drive:

  • Checking storage space – Knowing where your hard drive is located allows you to easily check the used and available space.
  • Adding new hard drives – If you want to upgrade your storage capacity, you’ll need to know how to access the internal drive bays.
  • Replacing or upgrading your hard drive – You can swap out the existing hard drive for a new one if needed.
  • Troubleshooting – If you’re having system issues, you may need to verify or repair the hard drive.
  • Partitions – Viewing the partitions on the internal drive can help troubleshoot or divide storage.
  • Wiping data – You may want to wipe and erase data before selling or recycling a Mac.

How to find your internal hard drive on a Mac

There are a few different ways to locate your Mac’s internal hard drive depending on your needs. Here are the most common methods:

1. Check About This Mac

The easiest way to find basic information about your Mac’s hard drive is to use the Apple menu:

  1. Click the Apple menu icon in the top left corner of your screen.
  2. Select “About This Mac” from the dropdown menu.
  3. Click the “Storage” tab at the top of the About This Mac window.
  4. You will now see details about your startup disk (main internal drive) including size, space used, space available, and more.

This will show you the high level details of your internal storage drive without needing any technical knowledge. From here you can check the capacity, see what types of files are using the space, and decide if you need to upgrade your storage.

2. Use Disk Utility

For more detailed information about your internal hard drive, you can use the Disk Utility application:

  1. Open your Applications folder, then go to Utilities and double click on Disk Utility.
  2. Make sure Show All Devices is selected in the top left corner so hidden devices appear.
  3. The left side panel will display all connected drives and volumes. Look for your internal hard drive here.
  4. Select the internal drive and detailed information will be shown on the right such as name, format, capacity, partitions, and S.M.A.R.T. status.

Disk Utility is helpful if you want to verify the health of your drive, reformat it, partition it, erase data, and perform other maintenance tasks.

3. Find the physical location

To find the physical location of your internal hard drive, you’ll need to open up the computer. This allows you to see where the hard drive is placed in relation to other components:

  1. Shut down your Mac and unplug all connected cables and devices.
  2. Use a Phillips screwdriver to unscrew and remove the back cover.
  3. Identify the hard drive which is usually a rectangular metal box or circuit board near the center.
  4. Some Macs have shortcut panels to access the hard drive without fully disassembling.
  5. Once located, you can remove the hard drive if needed.

Physically accessing the hard drive allows you to replace it, connect it externally, or diagnose any potential hardware issues affecting it.

How to check the hard drive on Mac startup

If your Mac is having issues booting up properly or starting up to a usable desktop, you may want to check the internal hard drive right from the startup.

Here are a few ways to check the hard drive while starting up your Mac:

  • Restart while holding the Option key to open Startup Manager – This will show available startup disks.
  • Restart while holding Command+R to boot to Recovery Mode – Here you can use Disk Utility.
  • Connect the hard drive externally using another computer or enclosure.
  • Start up from a bootable installer drive to test the internal drive.

Checking the hard drive at startup can help isolate the issue before fully loading the operating system. Any detected problems may require reinstalling macOS, erasing/formatting the drive, or replacing the drive entirely.

Tips for managing your internal hard drive

Once you’ve located your internal hard drive, here are some tips for properly maintaining it:

  • Monitor storage usage – Keep an eye on used space in About This Mac and delete unused files.
  • Use Time Machine backups – Regularly back up your drive to protect your data.
  • Keep macOS and apps updated – Updates can fix bugs and optimize performance.
  • Avoid force quitting – Forcibly quitting apps can corrupt files over time.
  • Watch drive health – In Disk Utility, check S.M.A.R.T. status for any issues.
  • Consider upgrading – Replace an old HDD with a faster SSD or get a larger drive.

Properly maintaining your Mac’s internal drive will keep it running smoothly for years to come.


Locating your internal hard drive is straightforward on a Mac once you know a few different methods. Checking About This Mac gives you a quick overview, while using Disk Utility allows more detailed status and maintenance. Physically removing the drive allows you to replace or externally connect it. Proper drive maintenance will ensure optimal performance.
