You can also drag the drive to your Trash to eject it if you see it on your desktop.<\/p>\n<p>Today, most removable media doesn\u2019t physically eject, but the command remains as a way to warn your Mac that you\u2019re about to unplug a drive. Here\u2019s why you should do it.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Ejecting_Protects_Your_Data_and_Your_Drive\"><\/span>Ejecting Protects Your Data and Your Drive<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are three major reasons why ejecting a removable drive within macOS before unplugging it is a good idea.<\/p>\n<p>When a drive is removable, that means that there is a chance that you might unplug a drive before a read or write operation is complete, potentially corrupting the data. Depending on how heavily used your system resources are (and how much data you are transferring), these processes might be queued and will not complete for some time.<\/p>\n<p>When you eject your drive, you are alerting macOS that you are about to unplug a drive, and this gives macOS and any <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>lications you\u2019re using a chance to complete all read and write operations before you unplug.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-716773\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/03\/disk_not_ejected_properly_message.jpg?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"The &quot;Disk Not Ejected Properly&quot; warning message on macOS Big Sur.\" width=\"650\" height=\"173\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p>The second major reason for ejecting is that sometimes, your Mac speeds up the apparent write process to a removable drive by temporarily keeping a copy of the data being copied in memory. This is called write caching. Ejecting allows the cached write process to finalize before you unplug, ensuring that no data will be lost. This was a much bigger deal back in the days when USB throughput speeds were slow (and Macs were slower as well), but even now, you could still potentially wreck your data if you unplug too soon after you think a copy process is complete.<\/p>\n<p>And finally, ejecting allows your Mac to safely remove power from the device when all data transfer operations are complete. For some smaller devices that receive their power from the USB or Thunderbolt socket itself, this can be a big deal. For example, suddenly cutting power to a spinning hard disk could potentially damage the drive. Even flash drives need power to complete write operations successfully, and you might unplug one too soon. Ejecting sends the signal to the drive to power down gracefully.<\/p>\n<p><strong>RELATED:<\/strong> <strong><em>When Should You Properly &#8220;Eject&#8221; Your Thumb Drive?<\/em><\/strong><\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Do_I_Need_to_Eject_a_Disk_Before_I_Restart_My_Mac\"><\/span>Do I Need to Eject a Disk Before I Restart My Mac?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The practice of ejecting removable drives has <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/apple.stackexchange.com\/questions\/67251\/is-it-necessary-to-eject-external-drives-before-logging-out-restarting-or-shut\">led some to wonder<\/a>\u00a0whether you need to eject a disk before you restart your Mac. The answer is no, you do not need to eject before powering down or rebooting. macOS automatically finishes up read and write operations as part of the shutdown or reboot process.<\/p>\n<h2 role=\"heading\" aria-level=\"2\"><span class=\"ez-toc-section\" id=\"Windows_Is_Slightly_Different_from_Mac\"><\/span>Windows Is Slightly Different from Mac<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If you\u2019re coming to a Mac from a Windows machine, you might be used to being able to quickly remove a drive without ejecting (or \u201cSafely removing,\u201d as Windows calls it). That\u2019s because Windows keeps write caching disabled by default, so you\u2019re far less likely to lose data as long as a transfer operation isn\u2019t currently in progress.<\/p>\n<p>On a Mac, there is no option to disable write caching for removable media, so you always need to eject. When it comes to your data, it\u2019s better to be safe than sorry.<\/p>\n<p><strong>RELATED:<\/strong> <strong><em>How to Never &#8220;Safely Remove&#8221; a USB Drive Again on Windows 10<\/em><\/strong><\/p>\n<\/div>\n<p><script>\n setTimeout(function(){\n  !function(f,b,e,v,n,t,s)\n  {if(f.fbq)return;n=f.fbq=function(){n.callMethod?\n  n.callMethod.apply(n,arguments):n.queue.push(arguments)};\n  if(!f._fbq)f._fbq=n;n.push=n;n.loaded=!0;n.version='2.0';\n  n.queue=[];t=b.createElement(e);t.async=!0;\n  t.src=v;s=b.getElementsByTagName(e)[0];\n  s.parentNode.insertBefore(t,s) } (window, document,'script',\n  'https:\/\/connect.facebook.net\/en_US\/fbevents.js');\n   fbq('init', '335401813750447');\n   fbq('track', 'PageView');\n  },3000);\n<\/script><\/p>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
