The only way it could avoid ruining the data there already is if the new
partition is created ("by hand", e.g. Norton's utility) overlapping the
end of the existing partition, and you make an imaginary file in the original
partition taking all of the used space. Otherwise shrinking the first partition
will make the FAT wrong (the 2nd copy will want to start earlier on the disk).
A very messy operation. Best to back up and repartition, unfortunately. Why do
you want to boot up on Dos 3.3?
