I think if there were real widespread issues with this, you'd be seeing it everywhere right now. Instead, it's likely a select number of people having hard drive issues and attributing that to the new console.
My intention to copy several PS4 games over to the PS5, and then safely disconnect the drive after using the appropriate menu option. At least for now, I don't think I'll play games them from the drive, just in case that's the thing that can potentially cause issues. I also don't intend to use the standby mode, as several journalists did say they had issues with that.
I'll also likely give it a couple more days to see if more people report having issues.
Sorry, does that mean you're actually running into problems, or you're concerned about potential problems?
