With the current NetBSD driver you are never sure if data is synced, unless
a rebuild has been issued through the BIOS management. NetBSD code will
_only_ tell you if a component has failed... just take a look at the
ld_ataraid.c
code.

I'd wish to be able to add spare disks and rebuild the arrays through bioctl(8)
in the future. We'd only need to look at FreeBSD's ataraid or Linux dmraid code.
