Prevent Hard disk from sleeping
I've been trying for days to back up my MacBook Pro, Ventura 13.5 but it keeps going to sleep. I have not been able to find the control to prevent the HD from sleeping while I'm doing the backup. Apple instructs to look for Energy Saver in the left hand menu under SysPrefs, but there isn't such an item. I've tried Battery, as advised in other posts, but there is nothing about hard disk even in the Options.
