If you used Disk Utility from macOS Recovery, you can now restart your Mac: choose Apple menu  > Restart. Type diskmgmt.msc into the box and press Enter. Press Windows+R on your keyboard to launch the Run dialog box. To do so, you first need to pull up the Windows Disk Management tool. The order of repair in this example was Macintosh HD - Data, then Macintosh HD, then Container disk4, then APPLE SSD. Assuming that the hard drive is installed properly, and is not, (by some horrible dumb luck) defective out of the gate, bringing it online is a very simple process. If youre repairing an external drive, make sure that its connected directly to your Mac using a cable that you know is good. In that case, follow these steps: Shut down your Mac, then unplug all nonessential devices from your Mac. Reinstall the original hard drive and verify that it shows up in Disk Utility - this will let you know that the SATA cables and connections on the logic board are functioning.

Keep moving up the list, running First Aid for each volume on the disk, then each container on the disk, then finally the disk itself. If Disk Utility cant see your disk, it also cant see any containers or volumes on that disk.

If you're asked for a password to unlock the disk, enter your administrator password.Īfter Disk Utility is done checking the volume, select the next item above it in the sidebar, then run First Aid again.

If the button is dimmed and you can't click it, skip this step for the disk, container, or volume you selected.

If there is no Run button, click the Repair Disk button instead. Get a visual breakdown of your disk space in form of an interactive map, reveal the biggest space wasters, and remove them with a simple drag and drop.

In this example, the last volume on the disk is Macintosh HD - Data.Ĭlick Run to begin checking the selected volume for errors. For each disk that you're repairing, start by selecting the last volume on that disk, then click the First Aid button or tab.
