I don't think NetBSD had a problem with big drives, but Bob Nestor has
pointed out that both mkfs and the installer DO have problems with
large drives. Basically there's a "big" read and write command, which
the booter didn't know about. So instead of writing to the upper 1G,
it wrote to the lower 1G, possably on top of a MacOS drive or worse..
It's been fixed in mkfs.
Take care,
