If you're concerned about one or two bits being toggled, a 512-bit hash will merely increase the chance of bit errors; on a noisy medium, using such a big "checksum" will BOTH detect and cause a high number of packet faults.
Nice to see a manufacturer producing a 2018 netbook. Netbooks were very useful devices. A lot of people around me used to have netbooks. Basically everyone who needs to produce (not just consume) on the go. Think students. I don't see how netbook concept should be dead. And they are fine qualitywise. You get what you pay for. They have awesome bang for the buck.
