My WD Black 4TB M.2 just came in and after fixing the heatsink I immediately swapped out the 2TB version.
Then while redownloading the games, I encountered an error CE-107880-4, which had something to do with the DRM of DLC contents, standard/premium/deluxe/PS4/PS5 editions of the game etc. Apparently the various combinations are too convoluted for the PS5 f/w to handle so it just spits out the error, or outright said enountered error, cannot download.
The game in question is Life is Strange True Colors Ultimate Edition, which includes PS4/PS5 versions of True Colors, plus Wavelength & costume pack (PS5?), deluxe upgrade which includes Wavelength & costume pack (?), PS4 Life is Strange remastered, PS4 Life is Strange Before the Storm Remastered, Wavelength & costume pack (PS4?) etc. Trying to download one or more of above components will create DRM conflicts in the system apparently.
