We\u2019ve seen situations where something as basic as a restart or even logging out and back in can solve the problem. There\u2019s no need to jump to drastic measures right away when a quick fix can often get the job done.<\/p>\n<p>If you\u2019ve already done all this, feel free to skip this section.<\/p>\n<div class=\"frame_bg frame_bg--default\"><div class=\"frame_bg--title\"><\/div>\ud83d\udc49 <strong>Tip. <\/strong>We&#8217;ve seen cases where third-party software interferes with external drives, so it&#8217;s a good idea to temporarily disable any apps you think might be causing issues. Or, try your external drive on a different MacBook or Mac to determine whether the problem is with the drive itself or your computer.<\/div>\n<h3><span class=\"ez-toc-section\" id=\"step_1_check_usb_connections_and_cables\"><\/span>Step 1: Check USB Connections and Cables<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The first thing to look at is the connection. A loose or worn-out cable is often the culprit, and checking this can save you a lot of time.<\/p>\n<p><img fetchpriority=\"high\" class=\"border-gray aligncenter wp-image-8287 size-full\" src=\"https:\/\/www.insanelymac.com\/blog\/wp-content\/uploads\/2024\/10\/external-hdd.jpg\" alt=\"Check USB connections\" width=\"1500\" height=\"1125\" \/><\/p>\n<ol>\n<li>Unplug the external hard drive and plug it back in. Make sure the USB cable is fully inserted into both the Mac and the drive. Even if the connection looks fine, a slight misalignment can stop the drive from mounting.<\/li>\n<li>If reconnecting doesn\u2019t work, the cable itself could be faulty. USB cables can wear out or get damaged over time. Try using a different cable that you know works with other devices to rule out a bad cable.<\/li>\n<li>Sometimes the USB port on your Mac is the problem. Plug the drive into a different port on your Mac. If your Mac has both USB-A and USB-C ports, try the other type with an adapter if needed.<\/li>\n<li>If the drive still doesn\u2019t mount, try plugging it into another Mac or even a PC. If it mounts on another device, the issue is likely with your Mac, not the drive.<\/li>\n<li>Some external hard drives, especially larger ones, require external power to operate. If your drive has a power cable, make sure it\u2019s plugged in securely. Without enough power, the drive won\u2019t mount.<\/li>\n<\/ol>\n<div class=\"frame_bg frame_bg--primary\"><div class=\"frame_bg--title\"><\/div>\ud83d\udc49 <strong>Tip. <\/strong>USB hubs can sometimes cause connection problems.

It offers a powerful <strong>byte-to-byte backup<\/strong> feature, which allows you to back up data from drives that macOS can\u2019t mount. It is different from regular backups. This feature is specifically designed to handle compromised storage devices. The byte-to-byte backup creates a complete virtual copy of your external drive so you can perform scans on this backup instead of your drive (scanning a compromised drive can sometimes cause additional damage.)<\/p>\n<p><strong>\u2705 Why Disk Drill Is our go-to tool?<\/strong><\/p>\n<ul>\n<li>Works with various storage devices, including external hard drives and USB drives.<\/li>\n<li>Supports all common external drive formats like <strong>APFS<\/strong>, <strong>HFS+<\/strong>, <strong>FAT32<\/strong>, <strong>exFAT, and NTFS<\/strong>.<\/li>\n<li>Offers an intuitive and modern design.<\/li>\n<li>Backup features.<\/li>\n<li>The ability to preview files.<\/li>\n<li>Disk Drill operates in a read-only mode (it only reads data from the storage device without any changes to it), and in the case of the byte-to-byte backup, this is even safer.<\/li>\n<li>It works on both macOS and Windows.<\/li>\n<li>Regular updates.<\/li>\n<li>Additional features like <strong>S.M.A.R.T. monitoring<\/strong>, which tracks your drive&#8217;s health to prevent issues before they happen, <strong>Clean Up<\/strong> tool that helps free up space, and a <strong>Data Shredder<\/strong> that securely deletes files you no longer need.<\/li>\n<\/ul>\n<p><strong>Here\u2019s how you can create a backup with Disk Drill:<\/strong><\/p>\n<ol>\n<li><a href=\"https:\/\/www.cleverfiles.com\/download.html\">Download<\/a> and install <strong>Disk Drill<\/strong> from the official website.<\/li>\n<li>Choose the option to create a <strong>Byte-to-byte backup<\/strong>.<img loading=\"lazy\" class=\"border-gray aligncenter wp-image-8291 size-full\" src=\"https:\/\/www.insanelymac.com\/blog\/wp-content\/uploads\/2024\/10\/disk-drill-btb-usb.jpg\" alt=\"Create a Byte-to-byte backup\" width=\"2422\" height=\"1632\" \/><\/li>\n<li>Select your external hard drive from the list of detected devices in Disk Drill.<\/li>\n<li>Click <strong>Create Backup<\/strong>, then choose a location where you want to save the backup. Make sure this location has enough free space\u2014ideally more than the size of your external drive. For example, if your external drive is 500GB, you\u2019ll need more than 500GB of free space on the destination drive or your Mac to store the backup.<\/li>\n<li>The backup process can take a while, depending on the size and condition of the drive. Allow Disk Drill to fully complete the backup without interruptions.<img loading=\"lazy\" class=\"border-gray aligncenter wp-image-8292 size-full\" src=\"https:\/\/www.insanelymac.com\/blog\/wp-content\/uploads\/2024\/10\/disk-drill-created.jpg\" alt=\"Disk image created\" width=\"2402\" height=\"1550\" \/><\/li>\n<\/ol>\n<p>Be aware that to recover files from this backup, you&#8217;ll need the PRO version of Disk Drill.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"step_2_how_to_recover_data_from_the_disk_image_back_to_your_external_drive\"><\/span>Step 2: How to Recover Data from the Disk Image Back to Your External Drive<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Now, scan the byte-to-byte backup you created.

These methods can help you tackle deeper issues that might prevent your drive from mounting properly.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"method_1_check_disk_utility_for_errors\"><\/span>Method 1: Check Disk Utility for Errors<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The first step in advanced troubleshooting is to check for file system errors using Disk Utility. This built-in tool can help identify and repair problems that may stop your drive from mounting.<\/p>\n<ol>\n<li>Press <strong>Command + Space<\/strong> and type \u201cDisk Utility\u201d to open the app. You can also find it in <strong>Applications &gt; Utilities<\/strong>.<\/li>\n<li>In Disk Utility, look for your external drive listed on the left side.<\/li>\n<li>If the drive is visible but not mounted, look for the <strong>Mount<\/strong> button at the top of the Disk Utility window.<img loading=\"lazy\" class=\"border-gray aligncenter wp-image-8297 size-full\" src=\"https:\/\/www.insanelymac.com\/blog\/wp-content\/uploads\/2024\/10\/disk-utility-mount.jpg\" alt=\"Click on the Mount button at the top\" width=\"2288\" height=\"1512\" \/><\/li>\n<li>Click <strong>Mount<\/strong> to try to manually mount the drive.

Click <strong>Run<\/strong> to start the process.<\/li>\n<li>Disk Utility will check the disk for errors and attempt to repair them. This may take some time.<\/li>\n<li>After the check is complete, Disk Utility will provide a report detailing any repairs made or issues found.<\/li>\n<li>After running First Aid, attempt to mount the external drive again. Select the drive and click the <strong>Mount<\/strong> button once more.<\/li>\n<li>If the drive mounts successfully, you can access your files through Finder.<\/li>\n<\/ol>\n<h3><span class=\"ez-toc-section\" id=\"method_2_use_terminal_to_manually_mount_the_drive\"><\/span>Method 2: Use Terminal to Manually Mount the Drive<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Alternatively, you can try to manually mount your external drive in Terminal. Sometimes, this method works when the drive fails to mount through the usual methods. The Terminal allows you to bypass potential issues that macOS may encounter when trying to automatically mount the drive.<\/p>\n<div class=\"frame_bg frame_bg--default\"><div class=\"frame_bg--title\"><\/div>\ud83d\udccc <strong>Note.<\/strong> Always double-check the drive identifier to avoid mistakes when using the mount command.<\/div>\n<ol>\n<li>Press <strong>Command + Space<\/strong> and type \u201cTerminal\u201d to open the app. You can also find it in <strong>Applications &gt; Utilities<\/strong>.<\/li>\n<li>In the Terminal window, type the following command and press <strong>Enter<\/strong>:<br \/>\n<strong>diskutil list<\/strong><img loading=\"lazy\" class=\"border-gray aligncenter wp-image-8299 size-full\" src=\"https:\/\/www.insanelymac.com\/blog\/wp-content\/uploads\/2024\/10\/diskutil-list-.jpg\" alt=\"This command displays a list of all connected drives\" width=\"1962\" height=\"1430\" \/><\/li>\n<li>This command displays a list of all connected drives, including internal and external drives. Take note of your external drive\u2019s identifier, which usually looks like \/dev\/disk2 or similar.<\/li>\n<li>Once you\u2019ve identified your external drive, use the following command to attempt to mount it:<br \/>\n<strong>diskutil mount \/dev\/disk2<img loading=\"lazy\" class=\"border-gray aligncenter wp-image-8300 size-full\" src=\"https:\/\/www.insanelymac.com\/blog\/wp-content\/uploads\/2024\/10\/diskutil-mount.jpg\" alt=\"Replace disk2s1 with the actual identifier of your drive\" width=\"1962\" height=\"1430\" \/><\/strong><\/li>\n<li>Replace disk2s1 with the actual identifier of your drive.

Resetting the NVRAM (Non-Volatile Random Access Memory) and the SMC (System Management Controller) can help resolve various hardware-related problems. These resets clear settings that might interfere with how your Mac interacts with external drives.<\/p>\n<div class=\"frame_bg frame_bg--success\"><div class=\"frame_bg--title\"><\/div>\ud83d\udccc <strong> Note<\/strong>. If your Mac uses <strong>Apple Silicon<\/strong>, simply restart the machine to reset both the NVRAM\/PRAM and the SMC.<\/div>\n<p><strong>Reset NVRAM\/PRAM<\/strong><\/p>\n<ol>\n<li>Shut down your Mac completely.<\/li>\n<li>Turn it back on and immediately hold down the <strong>Option + Command + P + R<\/strong> keys.<\/li>\n<li>Keep holding these keys for about 20 seconds. You might hear your Mac restart during this time.<\/li>\n<li>Release the keys and check if your external drive mounts properly.<\/li>\n<\/ol>\n<p><strong>Reset SMC for Macs with Intel processors:<\/strong><\/p>\n<ol>\n<li>Shut down your Mac.<\/li>\n<li>Unplug the power cord and wait for 15 seconds.<\/li>\n<li>Plug the power cord back in and wait for another 5 seconds before turning your Mac back on.<\/li>\n<\/ol>\n<p><strong>Reset SMC for MacBooks with a non-removable battery:<\/strong><\/p>\n<ol>\n<li>Press and hold <strong>Shift + Control + Option<\/strong> on the left side of the built-in keyboard, then press the power button at the same time.<\/li>\n<li>Hold these keys for 10 seconds, then release them and turn your Mac back on.<\/li>\n<\/ol>\n<p>After both resets, reconnect your external drive and see if it mounts automatically. If it does, you can access your files through Finder.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"method_4_reformat_the_drive\"><\/span>Method 4: Reformat the Drive<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>And finally, if everything else fails and your external drive is not mounting on macOS, reformatting the drive may be necessary. Keep in mind that this process will erase all data on the drive, but since we already covered how to make a backup of your drive, scan it for data, and recover it, your files should be safe, and you can proceed with formatting.<\/p>\n<div class=\"frame_bg frame_bg--default\"><div class=\"frame_bg--title\"><\/div>\ud83d\udccc <strong>Note.<\/strong> By the way, it is possible to <a href=\"https:\/\/www.insanelymac.com\/blog\/recover-formatted-hard-drive-mac\/\">recover data from a formatted hard drive<\/a> in some cases. If you accidentally formatted a drive without backing up your data first.<\/div>\n<ol>\n<li>In Disk Utility, look for your external drive. Click on it to select it.<\/li>\n<li>With your external drive selected, click the <strong>Erase<\/strong> button located at the top of the Disk Utility window.<img loading=\"lazy\" class=\"border-gray aligncenter wp-image-8301 size-full\" src=\"https:\/\/www.insanelymac.com\/blog\/wp-content\/uploads\/2024\/10\/disk-utility-erase-external.jpg\" alt=\"Slick the Erase button\" width=\"2130\" height=\"1380\" \/><\/li>\n<li>A pop-up will appear asking you to confirm. You\u2019ll need to choose a name for the drive, as well as the desired file format. Options include <strong>APFS<\/strong> (recommended for solid-state drives), <strong>Mac OS Extended (Journaled)<\/strong> (good for traditional hard drives), and <strong>exFAT<\/strong> (compatible with both Mac and Windows). Select the file format and click <strong>Erase<\/strong> again to confirm.<img loading=\"lazy\" class=\"border-gray aligncenter wp-image-8302 size-full\" src=\"https:\/\/www.insanelymac.com\/blog\/wp-content\/uploads\/2024\/10\/disk-utility-erase-format.jpg\" alt=\"Select the file format and click Erase\" width=\"2242\" height=\"1492\" \/><\/li>\n<li>Disk Utility will begin formatting the drive. Once the process is complete, you should see a message indicating that the drive has been successfully erased and formatted.<\/li>\n<\/ol>\n<h2><span class=\"ez-toc-section\" id=\"final_words\"><\/span>Final Words<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>After formatting, check to see if your external drive mounts automatically. If it does, that\u2019s great! But can you truly trust this drive? Are you comfortable transferring your files back to it? To help assess its reliability, you can <a href=\"https:\/\/www.insanelymac.com\/blog\/best-apps-to-test-mac-hard-drive\/\">check the drive&#8217;s health<\/a> with <a href=\"https:\/\/www.digitalcitizen.life\/simple-questions-what-smart-what-does-it-do\/\" target=\"_blank\" rel=\"noopener\">S.M.A.R.T.<\/a> Luckily, Disk Drill includes this feature.<\/p>\n<p>Here\u2019s how to check it: open Disk Drill and locate the S.M.A.R.T.
