12TB My Book needs password every time, but not others

I have MyBooks connected to my Windows 11 desktop PC. 3TB, 8TB, 12TB and 16TB All have different passwords set and the same settings, including sleep after 30 mins. However I find the 12TB ones (only) after sleeping need the password to access. The other 3 sizes are happy to sleep and reawaken when accessed without needing to reinput the password. Is there something particular about 12TB or hopefully a setting somewhere I can tweak?
