I listened while in the car so I was half paying attention. Yong Ya mentioned this in his video where if the system sits in rest mode for long enough, power is turned off and has to be manually turned on via the power button. After powering on the system shows an hdd error and rebuilds. He said Sony recognized this a known issue on Google modems and are working on a fix. I believe I heard he didn't have a Google modem and still had the issue. I'm wondering if data is being downloaded, or written to the drive, and the console automatically turns off or is triggered to shutdown. I have a similar issue with my PS4 Pro. It's always in rest mode, but sometimes I go to turn it on and the orange light is off and have to manually turn the console on. Afterwards, the console goes into the hdd rebuild/data check. It's happened a couple times and always come back okay. I get worried because I have a playable version of P.T.
