Racists terms in computer parts?

I never knew this, until I was swapping around a bunch of hard drives between computers. Every hard drive has a switch to change it from a master to a slave & vice versa. It’s actually printed on the manufactuerers label. Within the computer setup, the terms pop up again for you to choose which drive to be the master & which to be the slave. I don’t want to come off as sounding like some crazed person who wants to change everything to be politically correct, but seriously, wouldn’t ‘Primary’ & ‘Secondary’ be more appropriate for computer part termonology? Or is there something about computers I don’t know, that would prohibit the use of those terms?
