I use Rest Mode every day on my Pro as I have for years and have never had an issue (other than a few occasions where i have had to forcefully remove the power). Yesterday I added a 4TB Seagate USB hard-drive and everything was good but the first time I came out of Rest I had a black screen. Tutuapp 9apps showbox The PS4 hadn't crashed as I was still able to navigate the menus (From memory) and shut it down.. I didn't see a connection with the HD until it happened again.. And now I have tested, the same thing happens 70% of the time. I have read a few suggestions but nothing has helped, namely: Rebuilt the DB Changed HDCP from Auto to 1.4 Has anyone else seen this? Does anyone have any thoughts or suggestions?
