Dan,

That puzzled me, as it is dead easy to build a version identifier or
something similar into something like a RAID header, so I checked it up -
and sure enough Apple *does* build a version number into the header, which
changed from AppleRAID 1 (pre-Tiger) to 2 (Tiger). So it would appear to be
merely a matter of checking the version number - hardly onerous?

And since a corrupted disk may have headers which are unreadable...
