I believe it's common for PC-level hardware RAID cards to save the RAID
configuration on the disks themselves, which takes a bit of space and
(if it's done at the start of the disk) may make the disk unrecognizable
by standard tools, even with a JBOD setting.
The vendors presumably do this, among other reasons, so that replacing
a dead controller doesn't require your operating system and so on to be
running in order to upload a saved configuration or the like.
