When the RecoveryHD is missing, simply reinstall Sierra with the latest Sierra installer downloaded from the App Store – which shouldn’t affect your data but creates an additional RecoveryHD – or use the Recovery Partition Creator 4.

Check if a RecoveryHD is present by opening Terminal and entering diskutil list.

After the restore task has finished successfully, boot your Mac normally.

To replace either of the drives, backup your exisiting volume(s) first with Time Machine.

After destroying the LVG/LV the file system as well as system files or other files are corrupted and the remnants won’t be bootable. Removing one of the physical drives means removing one of the physical volumes and therefore tearing the LVG as well as the LV apart. Usually an algorithm ensures that system files are stored on the faster SSD but there is no guarantee. System files may also reside on both drives. The Logical Volume is the one mounted to root (and if enabled – the volume visible on the desktop).Ī file stored on the Logical Volume may reside on the SSD as well as on the HDD. Creating a default Fusion Drive means building one Logical Volume in the LVG spanning both physical volumes. The two physical volumes are part of a Logical Volume Group. The special volume on the HDD usually is the Recovery HD. Each of the physical drives contains three partitions: an EFI partition, a so-called physical volume and a special volume. A Fusion Drive is a composite of two physical drives: a fast but small SSD and a slower but larger HDD.
