>From what I understand, all DOS partitions you access via the current
msdos fs code need to be smaller than roughly 540MB.  This is because
when you go over 540MB, DOS uses 32K clusters, and the maximum cluster
size allowable by the NetBSD filesystem code is 16K.  It's probably
sheer lock that you're not crashing accessing both DOS partitions.

This info may be old and this may be fixed in current.  Then again, it
may not be.
