Disclaimer: I don't have a running NetBSD system; I've got a IIsi.
The fact you get a negative number kinda indicates that some of the
size values are kept as signed 32-bit integers, and 2^32 is 4Gb. I
know that on our RS/6000, filesystems were limited to <2Gb under AIX 3.
Though I'd have expected the problem to not show up at 1.5 Gb.
Hope this helps! It's certainly good for me to know; I've been drooling about
getting MacBSD up, and thinking about getting extra drives for it. I'll
stick to the afordable 730 MB Quantum drives if I make the plunge.
