- Disk1s1, the volume you boot from, mounted at /, shown in Disk Utility as Macintosh HD; disk1s2, ‘Preboot', not mounted, hidden; disk1s3, ‘Recovery', not mounted, hidden; disk1s4, ‘VM', mounted at /private/var/vm, hidden; The last 3 are grouped as Other Volumes in Disk Utility. They're required by macOS and shouldn't be removed.
- Went into disk utility and it only showed my hard drive and disk0s2, not macintosh hd. I went in to the apple store and they basically said they couldn't do nothing further more than to I guess reinstall osx and referred me to a data recovery place who was charging more than I expected to try and recover my data.
Disk Utility can find and repair errors related to the formatting and directory structure of a Mac disk. Errors can lead to unexpected behavior when using your Mac, and significant errors might even prevent your Mac from starting up completely.
3) Exited Disc Utility and started the Installation process. Problem: It froze on 18min left and I waited for about an hour. Following a post on the apple forums, I simply reseted it waiting for it to resume. However it did not come up. When I enter Recovery Mode, the Hard Drive is not there anymore.

Before proceeding, make sure that you have a current backup of your Mac, in case you need to recover damaged files or Disk Utility finds errors that it can't repair.
Open Disk Utility
In general, you can just open Disk Utility from the Utilities folder of your Applications folder. However, if your Mac doesn't start up all the way, or you want to repair the disk your Mac starts up from, open Disk Utility from macOS Recovery:
- Determine whether you're using a Mac with Apple silicon, then follow the appropriate steps:
- Apple silicon: Turn on your Mac and continue to press and hold the power button until you see the startup options window. Click the gear icon labeled Options, then click Continue.
- Intel processor: Turn on your Mac, then immediately press and hold these two keys until you see an Apple logo or other image: Command (⌘) and R.
- You may be asked to select a user you know the password for. Select the user, then click Next and enter their administrator password.
- From the utilities window in macOS Recovery, select Disk Utility and click Continue.
Select your disk in Disk Utility
Choose View > Show All Devices (if available) from the menu bar or toolbar in Disk Utility. Freeware macro program.
The sidebar in Disk Utility should now show each available disk or other storage device, beginning with your startup disk. And beneath each disk you should see any containers and volumes on that disk. Don't see your disk?
In this example, the startup disk (APPLE HDD) has one container and two volumes (Macintosh HD, Macintosh HD - Data). Your disk might not have a container, and it might have a different number of volumes.
Repair volumes, then containers, then disks
For each disk that you're repairing, start by selecting the last volume on that disk, then click the First Aid button or tab.
In this example, the last volume on the disk is Macintosh HD - Data.
Click Run to begin checking the selected volume for errors.
- If there is no Run button, click the Repair Disk button instead.
- If the button is dimmed and you can't click it, skip this step for the disk, container, or volume you selected.
- If you're asked for a password to unlock the disk, enter your administrator password.
After Disk Utility is done checking the volume, select the next item above it in the sidebar, then run First Aid again. 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.
In this example, the repair order is Macintosh HD - Data, then Macintosh HD, then Container disk3, then APPLE HDD.
If Disk Utility found errors that it can't repair
If Disk Utility found errors that it could not repair, use Disk Utility to erase (format) your disk.
If your disk doesn't appear in Disk Utility
Http www officeformac com. If Disk Utility can't see your disk, it also can't see any containers or volumes on that disk. In that case, follow these steps:

- Shut down your Mac, then unplug all nonessential devices from your Mac.
- If you're repairing an external drive, make sure that it's connected directly to your Mac using a cable that you know is good. Then turn the drive off and back on.
- If your disk still doesn't appear in Disk Utility, your Mac might need service. If you need help, please contact Apple Support.
My Mac Mini w/ Fusion Drive (that's a hard disk and an SSD pretending to be a single volume for better performance) froze and wouldn't boot. Nothing would make it boot normally again. Recovery mode was OK but couldn't erase the boot volume nor mount it via Disk Utility (I just got 'Unable to delete the core storage logical volume'), so reinstalling seemed impossible.
Fortunately, I figured out how to do it, using some help from a StackExchange post I found. See below for the details.
The magic incantation that fixed it was inspired by instructions I found here:
http://apple.stackexchange.com/questions/136590/how-can-i-delete-a-partition-corestorage-logical-volume-from-the-terminal
Note: THIS WILL WIPE YOUR HARD DISK. Only do this if you're completely ready to just burn it all down to the ground and start over with a blank boot disk.
Here are the steps:
- Boot the recovery volume, which will take you to an OS X Utilities page that shows four options: 'Restore From Time Machine Backup', 'Reinstall OS X', 'Get Help Online', and 'Disk Utility'. If you have gotten to this article you have probably already been into Disk Utility a few times already without success, so don't open Disk Utility.
- From the Utilities menu of the 'OS X Utilities' app, open Terminal. (Maximize the terminal window that opens so it's easier to see the output of the next step.)
- Run diskutil cs list . Using the mouse, copy the long alphanumeric string that's on the third line of output after 'Logical Volume Group'. That's the Logical Volume Group's universally unique identifier, a.k.a. its 'lvgUUID'.
- LAST WARNING: FROM HERE ON OUT THIS DELETES ALL OF THE DATA ON THE HFS+ LOGICAL VOLUME (but it doesn't delete the recovery partition).
Run diskutil cs delete FOO-BAR-BIZ-BAZ, where FOO-BAR-BIZ-BAZ was your lvgUUID. This deletes the logical volume group. diskutil will print things about erasing the physical partitions that made up the logical volumes, which in my case were /dev/disk0s2 (a 931GB partition on the internal hard disk) and /dev/disk1s2 (a 113GB partition on the internal SSD). Pay attention to the names of the devices that it just liberated on your system, since you'll use those device names in the next step.
At this point you have two empty HFS+ partitions that are not a Fusion drive anymore, so you'll want to rebuild the LVG from those two physical partitions. - Run this: diskutil cs create'Macintosh HD'/dev/disk0s2/dev/disk1s2 and adjust the /dev/. stuff to include the partitions that diskutil said it erased & mounted in the prior step.
On my Mac Mini it took about a minute to finish.
At this point if you run diskutil cs list you should see just a Logical Volume Group and as many Physical Volumes as you added (which is two in my case, disk0s2 and disk1s2), without any Logical Volumes yet. - Quit Terminal.app and run Disk Utility from the main 'OS X Utilities' app.
Disk Utility should show 'Fusion Drive' without any partitions in it, which is expected since we just created the Logical Volume Group without any Logical Volumes in it. - Select the Fusion Drive and run First Aid on it.
First Aid will immediately create a Logical Volume and format it, leaving one big partition of type'OS X Extended (Journaled)' named 'Untitled'.
Now you're free to do whatever you want with this empty disk. In my case, I erased it and created a new partition named 'Untitled' of type 'OS X Extended (Journaled, Encrypted)' since I want full-disk encryption.

(I tried to call it 'Macintosh HD' during the erase step, but Disk Utility failed to erase the disk and complained that name was invalid, so I just left it as 'Untitled', erased the disk, and then renamed it by selecting the Untitled volume in the left-hand-side list of devices, then clicking on the right-hand-side pane where the name Untitled was shown and editing it there.)

After this, I quit out of Disk Utility, and ran the 'Reinstall Install OS X' app. That does a network install which first required me to log in with my Apple ID and then downloaded the install files.
