It should be impossible to convince fdisk of this, because the partition
table format cannot support more that 63s (or 256h, or 1024h; however it
is safe to exceed 1024h in some cases).

You probably meant 64h/32s.  64s doesn't work.

This is the correct solution using fdisk too.  For all SCSI drives of
size 1G or smaller, use the geometry `m'c/64h/32s, where `m' is the
size in MB.  For larger sizes up to 8G, it is probably best to increase
the number of heads and sectors subject to the above limits.
