> so reloading the OS should leave all data intact?

The pattern data is held in battery backed RAM.
As long as a corrupt OS doesn't over-write any of the data there, it should
be fine once the OS is re-loaded.
The checksum for the OS would come up wrong even if just a single bit in the
whole OS was wrong.
But no problem would occur with the OS unless the section of code with the
bad bit were to execute, and the bad bit cause a change in the code that
made it do something bad.
