Someone else suggested sd0c too. I decided not to mess about with it any more
though and dropped the drives into a linux machine and dd'ed them there.
Seems to have done the trick anyway, but I'm a little wary now - although the
drives were identical vendor / models, the 'new' disk was reporting five more
cylinders than the 'old' one when under Linux (yet the same number of heads
and sectors per track), and I'm not sure of the reason for that.
Possibly there was a firmware "feature" in the "smaller" drive which
meant the
full drive capacity wasn't being utilised, but that seems like a pretty major
flaw in the days when a few MB here and there was precious. If not then why
someone / something (the NeXTstep installer, presumably) would format the
drive below total capacity, I don't know.
