Apple CoreStorage/File Vault/Fusion Drive Volumes


The macOS operating system has the following disk management systems:

File Vault , is a disk encrypted utility;

Fusion Drive is an Apple's hybrid drive technology;

CoreStorage is a logical volume management system.

 

R‑Studio supports all these technologies and can unlock their encrypted volumes (hard drives and images).

If the volume is partially encrypted, R‑Studio can recognize which part is encrypted and which isn't. It will  provide a correct access to the unencrypted and encrypted parts of the volume, provided that the correct password is entered.

Apple Fusion Drive

R‑Studio for Linux detects components of Apple Fusion Drive and creates virtual Fusion Drives automatically. At the same time, R‑Studio for Linux gives access to the individual components of the Fusion Drives (hard drives and images).

The Fusion Drive Components tab also allows you to manually disconnect or connect the components, for example, if they are such damaged that R‑Studio cannot recognize them as parts of a broken Fusion Drive. Select the object from the drop-down box and click the Connect button. R‑Studio displays the objects it recognizes as the components of the Fusion Drive in blue.
