Q: How to sync OneDrive to an external hard drive?

'OneDrive has become an integral part of my storage needs. I use it to store both work and personal files. However, my OneDrive is now flooded with files and narrowing my storage limit. Can I sync it to an external hard drive?'

Being one of the most popular cloud storage platforms, Microsoft's OneDrive offers a huge convenience to users. It not just sync all your files and data across different devices, but also back them up on the internet. Nevertheless, the free service gives 5GB storage to users, which seems to be less if you have a large number of files. Thus, depending on your storage needs, the OneDrive folder may consume a significant amount of storage. So, it is wise to have an alternative second storage drive. You can arrange this storage right into your system, inside an external hard drive, or even in another partition.

When you sync OneDrive data to your computer, then by default, it will save all the data on your local drive. You can find it in the User Folder. So, it might take a lot of storage space if you have lots of data to sync. Anyway, if your computer has a hard drive with a large capacity, then it may not affect largely. But it can pose a problem if it has just 128-256 GB SSD.

Fortunately, you can choose the location where your OneDrive will save all synced files. In short, it will allow you to store all synced data on a large capacity internal or external hard drive. Here we will discuss two different methods to do so.

Part 1: Benefits of Syncing OneDrive to an External Hard Drive?

OneDrive is quite popular among users as it allows everyone to manage their work and personal files from anywhere. You need to install the OneDrive application on your device. After that, the files that you store in the cloud will sync to the local storage in real-time. You can also enjoy a couple of additional benefits that are mentioned below.

1. Work In the Absence of Internet Network

No matter which device or platform you use, OneDrive lets you manage and access files from anywhere. Once you install the OneDrive application, it will sync all the data stored in it to the local storage. The syncing takes place in real-time. Besides, the real benefit of this platform is that you can use it offline. All you have to do is sync your OneDrive folder with any removable storage device, especially hard drive.

2. You Can Avoid Accidental Data Loss

There is nothing as frustrating as accidental data loss. The files may corrupt online due to various reasons, particularly ransomware virus attacks. Therefore, you must prefer to take offsite backup OneDrive folder. Syncing your OneDrive to an external hard drive will place an extra layer of protection to it.

As you can see, OneDrive is very convenient and handy when you manage multiple devices. Syncing keeps your photos, videos, and work files secure both online and offline. Now, the question is - how to sync this cloud platform to your external hard drive? Well, you can do it by using any of the two methods given below.

Part 2: How to Sync OneDrive to an External Hard Drive?

In the first method, we recommend using the best sync tool - AOMEI Backupper. It is a reliable and secure folder sync tool that comes with a lot of other features. Not just OneDrive, but you can also use this tool with any other cloud platform such as Dropbox and Google drive. With this tool, you can sync a few selected or all files of your OneDrive folder to an external hard drive.

Well, syncing can never be this easier. This tool lets you schedule a sync task as per your convenience. You can set it to sync your OneDrive folder on a daily, weekly, and even monthly basis. Besides, you can also try a real-time sync feature, which is available in the Professional version of this tool. In short, this tool is going to lessen a lot of hard work and time. So, let's find out how to use AOMEI Backupper to sync your OneDrive to an external hard drive.

Before we begin with the stepwise procedure, make sure that you have installed the desktop app of OneDrive, and it is properly configured. Once everything is well set in its place, you can go ahead with the steps below.

Step 1: Downloading the Software

You should first download the folder sync tool. For that, get the setup file of AOMEI Backupper software and install it.

Step 2: Go to File Sync

Once the software is installed, open it. You will see multiple options on the main console. From there, click on the 'Backup' tab, and then select 'File Sync' located on the right-hand side.

Step 3: Add OneDrive Folder

You will get an option to add the folder that you want to sync. Therefore, press the 'Add Folder' tab so that you can select the source folder, which is the OneDrive folder in this case.

Notes: You can further customize your folder selection process to only include a few selected subfolders.

Step 4: Select the Location

You selected a source folder in the third step. Now, you will need to choose a destination path i.e. a particular folder on your hard drive.

Step 5: Set the Sync Schedule and Start Syncing

As discussed earlier, this tool gives you an option to automate your syncing process. To do this, you can click on the 'Schedule' option at the bottom of the window and do the required settings. Once you complete setting up a schedule, click the 'Start Sync' button.

Now, let the software finish its task. The sync process will complete after some time. Thus, a sync tool comes in very handy when you want to sync OneDrive to external storage. Note that AOMEI Backupper can serve more beyond syncing. It will also help you clone the hard drive, do system backup, and many other tasks.

Part 3: How to Transfer OneDrive Folder to an External Hard Drive?

Users most often don't want to keep their OneDrive folder. In this case, they can change the location and their OneDrive folder will be redirected to another location. You will find the OneDrive folder placed in its default location i.e. C: drive of your computer. Thus, if your system drive corrupts, then it will also corrupt the files saved in your OneDrive folder.

Therefore, if you want to protect your important files and folders, then you must think of transferring the OneDrive folder to an external hard drive. You can transfer it manually by following the below steps.

Step 1: Go to the OneDrive settings by right clicking the OneDrive icon located on your taskbar.

Step 2: Now, head over to the 'Account tab' to locate an option that reads 'Unlink OneDrive.' When you click this option, a new screen (OneDrive setup window) will pop-up.

Step 3: In the third step, open the File Explorer on your computer and go to the OneDrive folder. Now, you can see a 'Move to' option on your screen. Make sure you select a folder located in your external hard drive.

Step 4: Now, move all the files and data of your OneDrive to the folder located in an external hard drive. After that, go to the OneDrive setup screen that was popped-up in step 2. Write down your login credentials to enter the OneDrive account.

Step 5: You will get a 'This is your OneDrive folder' window. At the bottom of this window, you can find a link 'Change location.' Click on that link to choose a new location for your OneDrive folder.

Step 6: Lastly, you should press the 'Use this location' button.

In this way, you can modify the location of your OneDrive folder, which was previously set to C: drive. This default folder location is not safe, especially if you think your system drive may corrupt over time.

While transferring your OneDrive folder manually may sound like a trouble-free task, it may turn challenging when you have a large amount of data. Moreover, doing any task manually brings in errors such as missing a particular subfolder, duplicating any important file, or accidentally deleting it. Therefore, you should go for an automated process, which ensures accuracy and complete safety.


No one can predict the life of computers or any other electronic gadget. These devices can stop working or start malfunctioning over time. In either case, you may lose your important data. Therefore, it is wise to have two separate homes for your data. Besides safety, you also get a lot of other benefits when you sync OneDrive to an external hard drive. We have already discussed all those benefits in this guide.

When it comes to syncing your OneDrive in real-time or schedule the entire task according to your preferences, then AOMEI Backupper should be your first choice. This amazing sync tool will ease your syncing task to a great extent.

Disk Drill brings deleted files back from the dead.

Most of the time, when you connect an external hard drive to your Mac’s USB port, you soon see it mount on the desktop. Apple likes to ensure these are easy to find, so they also appear in the Finder in the left-hand column under Devices, since Mac’s treat them the same way as another computer.

However, sometimes, an external hard drive doesn't show up. It’s annoying, especially when you need to transfer something right then. And besides, there can be a risk that data on the external USB pen, hard, or flash drive is corrupt, which means you can’t transfer what you need between devices at all.

Corrupt data can be one reason your Mac won't recognize an external drive, but there are other reasons too. Let’s take a look why this is happening and how you can get an external drive to appear on your Mac and get recover data to access to your documents.

How to fix an external disk drive that won't show up on a Mac

Why an external disk drive is not showing up? There could be a few reasons why a USB flash drive isn’t making an appearance.

Open an External Drive Not Showing on Mac

Get a huge set of top utilities for troubleshooting external hard drives not mounting on a Mac

Start with the basics:

  1. Check whether the drive is properly plugged in. It sounds obvious, but since this relies on a wire - either a USB cable or HDMI cable - if it’s not connected properly then it won’t appear on your desktop.
  2. Faulty cable. Assuming it’s plugged in correctly, not wobbly or loose, the cable could be at fault. Try connecting the same device with a different cable.
  3. Damaged USB or flash drive port. It could be a hardware issue with the Mac. If you’ve got another port, try connecting the device to that one.
  4. Reboot your Mac. Sometimes, if a USB disk won't boot, the cause is macOS issue. Hopefully, some data damage that can be fixed by restarting. Choose the Apple menu > Restart. Or press and hold the power button and, when a dialog box appears, click the Restart or press R. Restarting your Mac essentially clears your macOS’s memory and starts it up fresh.
  5. Incorrectly formatted drive. Not every external drive is optimized for Macs. It could be that you are trying to connect something only fit to interact with Windows devices. If you’ve got a PC or laptop, it’s worth connecting and seeing if you can access the files through another device. The best way to look for an incorrectly formatted drive is to go to
    Apple (in the top toolbar menu) > About This Mac > Storage.
    See if the external drive shows up here. For more information, go to the same menu option, then select System Report.
  6. Mac not formatted to display external drives on the desktop. It could be that your Mac already recognizes the device, but just isn’t showing its icon on the desktop screen. Even if that is the case, the drive will still appear in the left-hand column of the Finder menu under Devices. You should be able to access your drive that way, and, in the Finder menu under Preferences > General, you can check External Drives to ensure that from now on it shows up on your desktop too.
  7. Reset NVRAM. To do this, shut down or restart your Mac, switch it back on and immediately press these four keys together for at least 20 seconds: Option, Command, P, and R. It should look as though your Mac has started again; if it has, release the keys when you hear the second startup chime. Hopefully, the hard drive has shown up now.
  8. Check Apple’s Disk Utility to see if an external drive is showing up. Disk Utility is within System Preferences, or you can find it using Spotlight. If it is visible, then click the option to Mount, which should make it visible on the desktop and in the External Drives option in the Finder menu.

Unfortunately, if none of those options has worked and the external drive still isn’t visible, then it could have crashed, or be well and truly broken. But there might still be a way you can recover the data on the external drive.

How to show connected devices in Finder

  1. Go to the Finder menu and select Preferences (Cmd+comma).
  2. From General tab tick External disks to ensure that from now on it shows on the desktop.

In the Sidebar tab you can choose which folders and devices will be shown in the left-hand column of the Finder window.

How to add cloud storages to Finder

You can also mount cloud storage as local drive on your Mac. By connecting Google Drive, Dropbox, or Amazon to your computer, you get more space for securely accessing and sharing files. For your ease, add cloud drives to Finder with CloudMounter app, so that you keep them close at hand. You can read detailed instructions on managing cloud storage as local drives here.

Repair the failed external drives with First Aid

If your drive is having problems, you can try to fix them yourself with First Aid and therefore get access to your files. First Aid tool will check the disk for errors and then attempt a repair as needed. It helps to verify and repair a range of issues related to startup HD and external drive problems. If you are able to fix the hard drive or SSD in your Mac (or an external drive) using Disk Utility you will hopefully be able to recover your files.

To run Fist Aid on an external hard drive:

  1. Open Disk Utility. You can searching for it using Spotlight Search or via Finder > Application > Utility
  2. Check on your external hard drive, click the First Aid tab and select Run to start running diagnostics.

If First Aid successful in fixing errors, the external drive should be available to mount. If the utility unable to repair issues, your drive truly is broken or formatted using a file system that the Mac cannot read - in this way we suggest you follow the next steps to recover data from a damaged disk drive.

How to recover data from a crashed drive

Thankfully, there is an app for that. Disk Drill is the world’s premier data recovery software for Mac OS X. Powerful enough to retrieve long-lost, mistakenly deleted files from Macs, external hard drives and USB drives and camera cards.

Get a file recovery app

With Setapp you get a pack of professional tools for file recovery and Mac maintenance.

An easy way to recover lost files on an external hard drive

Providing you already have Disk Drill Pro version, which you can get automatically by downloading from Setapp:

  1. Connect your drive to the Mac.
  2. Quit all other applications on the Mac, especially those that may be trying to access the external drive (e.g. iPhoto, Words)
  3. Launch Disk Drill.
  4. Click on the external drive that you are trying to recover files from. If it has partitions, you will see all of them. If, however, you still don’t see any volume to the external drive then you may need to try some of the steps above again or read the Disk Drill Scanning FAQs.
  5. To avoid the external drive being accessed during the recovery process, click Extras next to the drive or drive partition or file, then select Remount Volume As Read Only. A padlock will appear, protecting the drive during the process.
  6. Now click Rebuild (or Recover) next to the file(s) you are trying to recover. Once the scan is finished - it may take some time if the files are large - a list of files will appeal.
  7. Next, click Mount Found Items as Disk button on the bottom-left below the scan results.
  8. Disk Drill “strongly suggest saving the files to a different drive than the one you are trying to recover files from. Saving to the same drive substantially lowers your chances of recovery.”
  9. A drive icon will appear, which once you double click will give you the option to open the files as you would do before they were lost. Drag them to another location, such as your desktop or a folder on your Mac.
  10. Open the files to ensure they have been recovered properly and safely eject the external drive.

Disk Drill does have other ways to recover lost files but assuming there aren’t complications, this method is the most effective. Disk Drill Pro recovery app is available from Setapp, along with dozens of Mac apps that will make your life easier. Never have to worry about a crashed or corrupted external drive again.

A few more tips on getting your files back

  1. Macs and third-party apps that look after Macs, such as Disk Drill and iStat Menus come with a S.M.A.R.T. (also known as Self-Monitoring, Analysis and Reporting Technology) status monitor. If a SMART check reports errors, then it could mean the hard drive is at risk of failing completely. Within Disk Utility and Disk Drill, there are several solutions for this: Repair Disk Permissions and Repair Disk. If neither work, it’s recommended that you backup all of the data from the disk, erase, then run a SMART check again. The external hard drive should show up as Verified.
  2. Partitions can get lost within hard drives, temporarily hiding all of the information contained within. Disk Drill can help to identify and restore this information.
  3. Within Disk Drill, you can restore data when a hard drive is damaged or add formatting, which is also something Disk Utility can help with.
  4. CleanMyMac, another useful app available from Setapp, can help you identify external hard drive errors and repair them. It is an essential tool worth trying when you’re having external hard drive difficulties.

Alternative ways to recover data from an external hard drive

Reset the System Management Controller (SMC) if your Mac shuts down when you plug in an external hard drive. Then use a different port to connect the external hard drive. If you’ve got a battery that you can’t remove:

  • Shut down and unplug the power adapter
  • Press Shift-Control-Option and the power button at the same time. Do this for 10 seconds
  • Release all keys
  • Plug the power adapter back in and switch your Mac back on

For Macs with removable batteries, you need to switch them off, remove the battery, then press and hold the power button for 5 seconds. After that, put the battery back in, plug in the power adapter and switch the power on again.

What’s your file format? One reason your Mac isn’t recognizing the hard drive is the file format. Windows uses NTFS file formats, while Macs, up until the introduction of Sierra, have used HFS+. Now, Apple has introduced the Apple File System (APFS) for newer operating systems. It is possible to format a hard drive so it can be read on Mac and Windows computers, providing you format using exFAT. However, if you’re having problems accessing the files and the issue is due to formatting, you will need to connect it to a device it can be read on, and then format the files correctly for the computer you are going to use it on next.

How to make Ext2/Ext3 drives readable on Mac

The common issue is Ext2- and Ext3-formatted drives are not readable on macOS. There are two ways to access such external drives on your Mac – via Linux OS or FUSE system. The easiest would be installing Linux to a secondary drive or virtual machine.

If you go with Linux installation, dual boot your Mac with Linux on another drive and use FAT32 as a transfer intermediary. If you don’t have a drive to install Linux to, use virtual machine as an interface for it. Transferring can be done the same way – with FAT32, or via network.

Another option for reading Ext2/Ext3 disks is mounting disk with Filesystem in Userspace (FUSE). Basically, it works as an extra interface enabling file system access via specially installed modules. Here’s how to mount drives with FUSE:

  1. Install FUSE for macOS or MacFUSE as well as fuse-ext2 module.
  2. Use the following Terminal command to enable Disk Utility’s debug menu and see all partitions: defaults write com.apple.DiskUtility DUDebugMenuEnabled 1
  3. Attach your Ext2/Ext3 drive and locate the device name via Disk Utility.
  4. In your user account, create a folder to be used as a mount point.
  5. Use the following Terminal command to mount the drive as read-only: fuse-ext2 /dev/disk2s2 /Volumes/mountpoint
  6. For write support, use the command: fuse-ext2 -o force /dev/disk2s2 /Volumes/mountpoint

And that’s not the only case where Terminal helps you access external drive.

Employ the handy all-powerful Terminal, which always comes forward with solutions for difficult problems. Especially if System Information does recognize the USB or hard drive, but continues to hide it from you, disconnect the drive and try to find it using the Terminal, which you can find in Applications > Utilities.

  • Once in the Terminal, type in the command diskutil list
  • A list with information about volumes and drives should appear
  • Look for a section labelled /dev/disk_ (external, physical)
  • Make a note of the whole line after the word disk
  • Now put the following command into the Terminal diskutil info disk followed by the number or digits assigned to that disk
  • Now you should see detailed information about the drive, therefore confirming that your Mac can and does recognize it
  • Eject using the Terminal by entering the command diskutil eject disk followed by the number or digits assigned to that disk
  • Physically remove the disk from you Mac
  • Plug it back in and your Mac should recognize it

Hard Drive Sync Software Mac Free

Console is also reliable when it comes to solving tricky problems, although it isn’t always that easy to use. You can find Console under Applications > Utilities > Console. Console shows if an external drive or any error is detected under the Errors and Faults tab. If no errors show up, then the problem is not caused by the device.

External Hard Drive Sync Software

To sum up, there are lots of potential solutions for a Mac not reading an external hard drive. If we were to pick one, Disk Drill seems to be the most well-rounded, offering plenty of customizations and power in an easy-to-use interface. Disk Drill Pro recovery app is available via Setapp, along with 150+ Mac apps that strive to make your life much much easier. At the very least, you’ll never have to worry about a crashed or corrupted external drive ever again.
