Which affect the other partitions because they _cannot_ be written to at
the same time, duh!

You are the one that brought up corruption, not me.

You don't have to be an engineer to realize you can't perform write
operations to two different partitions at the same time on the same
disk. I still say I/O is I/O, you're either writing to or reading from a
specific place on one platter of the disk which prevents reading/writing
from any other place on the disk ( I/O ).
