I wish to have two volumes on a drive (not SSD); one HFS+, one APFS.

Would it be possible to have these on an HFS+ partition or APFS?

  • Can you please clarify what you mean by volume and partition?

  • Yes, sorry, that was very poorly phrased. If having multiple volumes on the same disk, HFS+ and APFS, would it be better to format the disk itself as APFS or HFS+?

Well, you would need a separate partition for each volume type. In other words, APFS type partitions can hold multiple volumes, but each must be a APFS volume. HFS+ type partitions can hold a single volume which must by HFS+ type.

In addition the first partition is usually a EFI type partition which contains a single volume of FAT32 type. So, you would need at least a total of three partitions on the drive.

No single partition type can support both HFS+ and APFS volumes.
