366 /* Here follows some rather intricate and (probably) fragile code to find the list of available
367 * "real" drives on macOS that we might want to write a DCP to.
369 * We use the Disk Arbitration framework to give us a series of mount_points (/dev/disk0, /dev/disk1,
370 * /dev/disk1s1 and so on) and we use the API to gather useful information about these mount_points into
371 * a vector of Disk structs.
373 * Then we read the Disks that we found and try to derive a list of drives that we should offer to the
374 * user, with details of whether those drives are currently mounted or not.
376 * At the basic level we find the "disk"-level mount_points, looking at whether any of their partitions are mounted.
378 * This is complicated enormously by recent-ish macOS versions' habit of making `synthesized' volumes which
379 * reflect data in `real' partitions. So, for example, we might have a real (physical) drive /dev/disk2 with
380 * a partition /dev/disk2s2 whose content is made into a synthesized /dev/disk3, itself containing some partitions
381 * which are mounted. /dev/disk2s2 is not considered to be mounted, in this case. So we need to know that
382 * disk2s2 is related to disk3 so we can consider disk2s2 as mounted if any parts of disk3 are. In order to do
383 * this I am picking out what looks like a suitable identifier prefixed with PRT from the MediaContentKey.
384 * If disk2s2 and disk3 have the same PRT code I am assuming they are linked.
386 * Lots of this is guesswork and may be broken. In my defence the documentation that I have been able to
387 * unearth is, to put it impolitely, crap.
