Nope. I tried, but this is a problem with firmware that says there is 159=
blocks per track, 5 heads and only 793 blocks per cylinder (while 159 * 5=
is
795). AmigaOS' FFS handles it just ok, AFS thinks that there's 795 blocks=
per cylinder, overestimates size of the partition and overwrites beginnin=
g
of the next one.
What NetBSD does is unknown to me, perhaps there is someone who knows... =
I
guess patching the kernel to calculate number of blocks per cylinder
correctly wouldn't be that difficult, but there may be more to it that ju=
st
the number of blocks...

Some guy from Australia who suffers from similar problem was bugging
Quantum, but they said he needed to send the disk for replacement. :( Not=
so
easy...
