To activate these two services, select System Preferences from the Apple menu.Ĭlick Keyboard on the System Preferences dialog box. To open a Terminal window to a specific folder from Finder, you must make sure the New Terminal at Folder and New Terminal Tab at Folder services are activated. The article linked to above also shows you how to add the “Open command window here” option to the context menu when you’re in a folder.Ī Command Prompt (or PowerShell) window opens directly to the selected folder. Or you can add the ‘Open command window here’ from the context menu and use that to open a Command Prompt window to the folder. If that’s too much physical labor, you can also re-mount the DVD from the command line, and then eject it as described in the previous paragraph, but I haven’t looked into the mount command (or commands) yet.On Windows, you can press the Shift key and right-click on a folder to open a PowerShell window directly to that folder. After you plug it back in, MacOS will mount it for you, and then you can press the Eject button on your keyboard, the Eject button on the DVD drive itself, or the Eject icon in the Finder. Give that a try first.Īssuming that doesn’t work, and you’re using an external drive, another simple process is to briefly unplug the DVD drive from your system, and then plug it back in. This step depends on the DVD player you’re using, but if you’re lucky you may just be able to press the Eject button on your keyboard.

Because you unmounted the DVD, you have to do something to eject the DVD from the DVD drive. You can also try other options with the dd command, such as trying to control the block size, but I’ve found that the default command runs faster than any block size command arguments I’ve tried. I’ve been backing up a few DVDs today using an external USB 2.0 DVD drive, and I’ve found that the process takes 30-60 minutes, depending on the size/contents of the DVD. Once you hit, the backup process will start. Because my identifier is disk2, I use this command to unmount my drive: The next thing you need to do is to unmount the CD/DVD drive. That’s all you need to know for this step.

This means that the device that the Mac/Unix system uses to communicate with the DVD drive is /dev/disk2. In my case, the last entry is the entry for my DVD drive - which you can tell in a variety of ways, including the words external and DVD, as well as the size - and the identifier is disk2.
