Possibly you've managed to get overlapping partitions.
Either that or netbsd just doesn't like writing to the disk,
or maybe the system powered off before the last write finished.

The main superblock is 8k down the partition (size 8k) and the first
alternate folows it immediately.

However I'd actually suggest trying to install a newer version.
Sysinst in netbsd 2.1 and 3.0 is a lot less user hostile.
