Sometimes the drive won’t unmount no matter what, and I get the dreaded “The disk wasn’t ejected because one or more programs may be using it” or “The volume cannot be ejected because it’s currently in use” messages.</p>

He’s had this happen routinely with a Mac mini using flash drives and external hard disk drives (HDDs). I’ve definitely seen some of this behavior, though it’s not routine. If OS X “understands” why it can’t unmount a drive, starting a few releases ago, it will tell you. But the dialogs Kurt is seeing aren’t the informative kind that tell you which app is involved.</p><p class="jumpTag"><a href="/article/3061175/os-x/what-to-do-when-a-hard-drive-wont-unmount-in-os-x-el-capitan.html#jump">To read this article in full or to leave a comment, please click here[/url]</p></section></article>
