m not a doctor but my understanding of high blood pressure as a chronic illness is that it’s a long term game. High pressure on your arteries and heart over many years increases the risk of cardiovascular disease. It’s less relevant as a short term problem.
This isn't always the case. Some cases of hypertension that are not lifestyle related can reach life threatening levels (as in, embolism or burst blood vessel or heart failure) if not treated regularly.
Can you hear or feel the drive spinning with the power and USB plugged in?
Do you have a second computer (Linux or windows) to also try it in?
A brief search seems to indicate this drive is a minimum of 15 years old, which is an incredible age for a portable mechanical drive. I would honestly be preparing yourself to be dealing with this drove finally being cooked beyond repair. Sure hope you kept backups of what was on it!
