Likely she is moving again. Without the exact location of the Planet Earth, she can no longer point her antennae to report in. That storm was a long duration problem, and the reboot would go back to her original programming from a decade plus before.

She would "loose" Earth, having moved way past her originally intended location and mission time. A hard drive would be fine, as long as the seal was intact.

Storm covered a third of the planet, couldn't out run it. They should have used the watchdog timer to reactivate the processor after a hard shutdown; to save power. They could have doubled the memory retention time that way.
