When I changed a partition table of same disk, sd0 didn't work well.
I didn't record data before a partition table, but maybe,

sd0a	about 900M?(NetBSD)
sd0b	128M(swap)
sd0c	about 3100M
sd0d	about 600M(HFS)
ad0e	about 700M?(not use)
ad0g	about 600M?(NetBSD)

At this time,

sd0a is 2400MB, sd0b is 256MB, sd0d 430MB. When I write 100MB data from ftp server
to sd0(through sn0), my machine hungs up and becomes kernel debug mode in folloing,
