macOS can create several software RAIDs from disks connected to a Mac computer: RAID1 (Mirror set), RAID0 (Stripe set), and Concatenated disk set.
R-Studio automatically detects disks from Apple RAID sets and creates their virtual RAIDs automatically. At the same time, R-Studio gives access to the individual members of the Apple RAID sets (hard drives and images).
R-Studio shows broken Apple RAIDs in pink.
If recognized members of a Apple RAID are added to R-Studio (including disk images), R-Studio automatically adds them to their respective Apple RAIDs.
When Apple RAID members are such damaged that R-Studio cannot recognize them as members of broken Apple RAIDs, you may add them manually. Control-click the required Apple RAID, select Add missing disks on the contextual menu and select the required object(s) on the Add missing disks dialog box.
You should place the objects on their correct places.
R-Studio shows such Apple RAIDs in blue:
