there's no problem to create partitions which have exactly the same size
as the old ones.
your disks can be from a different manufacturer, have differnt sizes,
different number of physical heads or anything else.

if you set up your disks to have the same geometry (heads, cylinders,
sectors) you can have partitions exactly the same size. (the extra size
of larger disks won't be lost.)

read "man fdisk" and have a look at the parameters -C -H and -S...
