![]() Check out:įirst Aid: Verify and Repair HFS+, APFS Drives with Disk Utility As far as I know, it is better to run First Aid on volumes, then on containers and then on disk, in such order. Is that normal? If not, how to restore it?ģ. Yet, it does not show in macOS 10.15 Catalina. In macOS 10.12 Sierra for instance, the macOS Recovery partition shows as disk icon to select when booting pressing the Option key. Is that and the final DiskWarrior 6 release days, weeks, months or years away? Or is it not known at the moment, and maybe it is never released? That would be great! Thanks!Ģ. For instance, do they have all required documentation from Apple? If not, when is it expected? Even a tentative date would be great. ![]() Does it make any difference or is it recommended to run First Aid from the booting disk, or booting from macOS Recovery, or booting from other disk? Could it be better to do it using applications like Micromat TechTool Pro (until Alsoft DiskWarrior 6 for APFS is released)? It would be great if Rusty Little (DiskWarrior Project Manager) could say something about the future DiskWarrior 6 to rebuild the directory of APFS disks (without breaking the NDA with Apple, of course!). I wonder why Apple does not allow “Disk Utility – First Aid” to check all (disk, containers and volumes) at once with a single click. This all makes sense, apart from Disk Utility’s apparent inability to unmount volumes in order to check a container, but isn’t what the user is told in the app’s Help book. To check and repair all volumes in a container, you must first eject each of its volumes, then select the container and click on the First Aid tool. To perform full checks on an APFS volume, you should select that volume (not its disk or container) before clicking on the First Aid tool. If that’s a disk, then First Aid checks and repairs at that level, including the disk’s partition map and EFI partition, not its volumes. How this currently works is that performing First Aid depends on the item which is selected. The description of Disk Utility’s First Aid command therefore appears incorrect. if there are snapshots on the volume, these are checked individually.However, if it can’t, try unmounting the volume before running First Aid, and mounting it manually again afterwards.įile system objects which are checked on each volume include: When run on a mounted volume (not its container), Disk Utility is usually happy to unmount that volume before performing its checks, then re-mount the volume at the end. ![]() If you manually unmount all the volumes in a container and run First Aid on that, or select a volume and run First Aid on that instead of its container, then each volume undergoes a full check on its file system., using the command If you try checking a container on an external APFS disk without ejecting all its volumes, First Aid usually returns an error code -69566 because it can’t apparently unmount the volumes itself. Unmounting its volume(s) make no difference to that, but leaves its container and volumes unchecked. Run First Aid on an external APFS disk and the same checks are made as on an HFS+ disk, covering the partition map and EFI partition. As those require the volume(s) to be unmounted, this is discouraged when running in normal mode, and better performed in Recovery mode. If you want to check the container or volumes on it, you have to select each individually then click First Aid. Run First Aid on your APFS boot disk and the same checks are made as on an HFS+ disk, including the partition map and EFI partition. On completion of any repairs, the volume is mounted again. Is then run on each available volume, which checks its HFS+ file system in full. Run First Aid on an HFS+ volume and the volume is first unmounted, and the command Other volumes on that disk aren’t checked at all.
