When creating an encrypted partition on a OS X system a Core Storage partition is created. I wont go into details about these partitions but you can do a "man diskutil" on a OS X system to learn more. A disk partitioned with such a partition looks like this on OS X (output of "diskutil list"): /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *2.0 TB disk2 1: EFI EFI 209.7 MB disk2s1 2: Apple_CoreStorage 250.0 GB disk2s2 3: Apple_Boot Recovery HD 650.0 MB disk2s3 4: 516E7CBA-6ECF-11D6-8FF8-00022D09712B 1.7 TB disk2s4 Note partition (or slice) 2 On FreeBSD "gpart show": => 34 3906963389 da0 GPT (1.8T) 34 6 - free - (3.0K) 40 409600 1 efi (200M) 409640 488281256 2 !53746f72-6167-11aa-aa11-00306543ecac (233G) 488690896 1269536 3 apple-boot (620M) 489960432 3417002984 4 freebsd-zfs (1.6T) 3906963416 7 - free - (3.5K) So obviously "!53746f72-6167-11aa-aa11-00306543ecac" is the magic UID for the Core Storage slice. All this applies to GUID partition tables. I have no idea what the situation is with other partition schemes but I doubt that Core Store Volumes can be created anywhere else than GPT. While not really a serious bug, I still think this should be added to the list of known partition types. P.S.: The output above is from the exact same disk. Apple uses base-10 values instead of base-2 values so everything appears to be larger.
