Disk Drill brings deleted files back from the dead.
Disk Utility is the perfect choice for creating a partition of your Mac’s hard drive. How to Backup a Mac to an External Hard Drive. Insert your drive and use the Disk Utility app to format it. Open two Finder windows. One should show your internal drive, while the other should.
Disk Utility is a built-in app in macOS. When you open this app, it will show all the hard drives and devices on your Mac. You can use the erase function to format a hard drive or device. However, when the hard drive has been erased by Disk Utility, most of the formatted data can be recovered by data recovery software. Start Menu for Mac.
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.

Start with the basics:
- 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.
- 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.
- 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.
- 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.
- 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. - 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.
- 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.
- 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
- Go to the Finder menu and select Preferences (Cmd+comma).
- 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:
- Open Disk Utility. You can searching for it using Spotlight Search or via Finder > Application > Utility
- 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.

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:
- Connect your drive to the Mac.
- Quit all other applications on the Mac, especially those that may be trying to access the external drive (e.g. iPhoto, Words)
- Launch Disk Drill.
- 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.
- 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.
- 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.
- Next, click Mount Found Items as Disk button on the bottom-left below the scan results.
- 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.”
- 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.
- 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

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

If there’s one thing you need to remember when dealing with high-tech devices, such as laptops and desktops, is that you should always have a recent backup on hand. While it’s true that Macs are as dependable as computers go, no one is protected from their processor overheating, battery dying, files being corrupted by malware, or just a spilled cup of coffee.
External hard drives have been around for decades. First they connected to your computer through USB-A ports and could hold just a few dozen gigabytes. Eventually, they learned to transfer files over WiFi and grew up in size to a few terabytes — becoming de facto the best personal cloud storage available to most people.
Get the best backup app
Keep data safe, whatever hard drive you use. With Get Backup Pro, there’s zero chance you lose anything important on Mac.
But with the explosion of smartphones and streaming services, the amount of media data being saved on our devices has greatly exceeded what regular hard drives can offer. Today, most of us need a robust and expendable home cloud storage solution that’s able to protect our data seamlessly in the background.
What Is A NAS Hard Drive?
NAS (or network attached storage) in many ways is just the right answer for those who want to upgrade from outdated external hard drives and beginner My Cloud app look-alikes.
A network attached storage device is not only capable of wirelessly storing everything you’ve ever created (they generally start at about 2 TB) but also divide its capacity between a few people (so every family member could have their own drive, for example), stream media to Apple TV or Bluetooth speakers directly, and act as a central hub for all storage, with all your other hard drives connected to it.
So let’s look at the best NAS for Mac on the market in 2020, covering every target audience segment.
Simple: Western Digital My Cloud Home
When you just want to graduate from an external hard drive to a network attached storage for Mac, there’s no better candidate than WD My Cloud Home.
Western Digital doesn’t even call this network storage a NAS drive but rather addresses it as a personal cloud storage device. Still, My Cloud Home encompasses all the attributes of grownup NAS drives without the price tag. It goes from 2 to 8 TB in storage capacity, can save all your information via WiFi automatically, allows remote access through a My Cloud app, features shared folders as well as individual volumes, and is capable of streaming to Sonos, Google Chromecast, and more — all starting at just $159.99.
Powerful: Western Digital My Cloud Expert Series EX2 Ultra
If you want to combine the ease of use we’ve all come to expect from WD devices with a power of true NAS storage, take a look at the WD My Cloud Expert series.
The EX2 Ultra is a real NAS drive that could come unpopulated (without hard drives) so you can install your own storage or take up to 28 TB right from the manufacturer. Unlike My Cloud Home, EX2 Ultra introduces RAID (redundant array of independent disks) options that let its two hard drives clone each other and carry the same information for maximum protection.
In addition, WD My Cloud Expert EX2 Ultra is powered by a dual-core processor for ultra-fast streaming and encrypts your hard drive volumes by default.
Affordable: Buffalo LinkStation 220D
In some cases, you might care less about how intuitive your NAS storage is, what you’re really after is a cheap NAS with good security built in. That’s where you should try Buffalo LinkStation 220D.
While LinkStation 220D might not win any awards for its user-friendliness, it’s a straightforward unpopulated NAS for Mac that starts at $119.99 and includes RAID support (with an additional USB-A on the back) as well as drag-and-drop backups.
You could set up a shared folder through Buffalo’s Navigator app, but it would be more difficult than you think. Same with getting your iTunes streaming server to work. Overall, good enough for straightforward tasks.
Advanced: Synology DiskStation DS218
Stepping into high-end but still consumer-oriented NAS storage solutions, we can find Synology DiskStation DS218. It comes unpopulated to let you combine your own storage devices and features a Gigabit Ethernet port for connecting to your router as well as three USB-As for any other storage volumes you might be using.
DiskStation DS218 is RAID-enabled and can act as a media server with real-time 4K video transcoding to Apple TV or any other player — all running on a quad-core 1.4 GHz processor. Some would say DiskStation might simply be too much for a casual user, and they will be right. But for some, it’s just what they were looking for all along.
Professional: Drobo 5N2
Those who work in the fields of photography, animation, or video production know how much unique data could be worth. From that perspective, Drobo 5N2 is not an expensive device at all, although it starts at about $550 unpopulated.
Drobo 5N2 features five hard drive slots, some of which can be used for RAID and some for actually expanding the NAS storage capacity. Two Gigabit Ethernet ports can be combined into one to provide astonishing transfer speed for the high-end devices that can handle it. This NAS even features its own internal battery for a complete fail-proof setup.
How to properly back up your Mac
Whether you’re using NAS or a regular external hard drive for your backup plan, you need to know how to approach backups in a comprehensive manner, so you don’t forget any important files.
Get Backup Pro is one of the most versatile backup managers you can find. It instantly connects to your NAS drive and offers incremental backups on a set schedule or cloning options that allow you to reboot your Mac from an external drive should it break. Get Backup Pro’s speed and reliability are unparalleled, far exceeding those of Time Machine, for example.
How to recover lost files from an external drive
Mistakes happen and regardless how robust your backup solution is, there would be a moment when you’d accidentally delete a file not backed up anywhere else, be it from your Mac or an external drive. What do you do now?
Disk Drill is master data recovery software that’s able to get into the deepest corners of your data volumes and retrieve information that you thought was forever gone. Your best friend here is to act quickly and launch Disk Drill right after you saw a much-needed file disappear — that’s why keeping this app in your toolkit at all times is a true secret lifesaver.
