comp.sys.3b1 is the correct newsgroup (and, still, for awhile, unix-pc.*)

The 64MB drive selection is the correct one due to how spare sectors are
allocated on the drive.

The largest HD on an unmodified 3B1 has 8 heads and 1024 cylinders, uses
MFM recording, and has 17 sectors per track; you should pick the entry
with these numbers, or select "other" and simply enter these numbers at
each prompt.

If you're truly starting from scratch, you may wish to consider some mods
that permit up to two 150MB HDs.  Again, browse comp.sys.3b1
