i assume you are using the official supply.
if not, recommend you get one.

the official supply can provide 1.6A to usb. How much does the drive say it draws? (check the label)
spinning rust - may require more power than the PI is designed to deliver.
official docs: https://www.raspberrypi.com/documentati ... al-bus-usb

you could use a powered usb hub. but make sure it does not back-feed to the PI.
if you search the forum, people have identified ones that work.
