Hi,
It's been a while since there's been any traffic on this list so I guess I have the honour of posting the first mail of 2005.
My question is not an HFSx one per se, however, it's it in the ballpark: Since OS X.3 came along, the partition map is now being populated by default with a number of Apple_Free partition entries interspersing the user's specified partitions. I'm curious whether anyone knows the rationale behind this. I have my theories but I'm probing for a more definitive response, if one exists.
Also, if a better venue exists for general Mac-formatted device questions exists, perhaps someone from the list can share that information.
Thanks,
Gord Beatty

Not quite sure being on the spot, but since the Apple specs say that the whole space on a disk must be allocated in the partition map, it can happen that the division between the main partitions (driver partitions, payload partition, etc.) doesn't make the total of the sectors on disk. The rest should be represented in the partition map by a Apple_Free partition.
My 2 cents...
