All it takes is partition /table/ modification for partitions to
disappear with the actual data/filesystem completely intact, so as long
as nothing was since written to the region where the table pointed.

Fun aside: this is how you grow a partition (as long as you still have
"unallocated" space): delete the partition to grow using (c/f/g)disk or
(g)parted or whatever, then create a new one with the same starting
sector but obviously larger size. The filesystem remains the same size
(and data) as before until you expand it to your now-larger partition size.
