I have a 2TB My Passport External Hard Drive that I have been using for the past few moths with no issues. A couple of days ago I accidently pulled the cord out of the USB port without properly ejecting. Since then, when I plug the hard drive into the computer (directly into the USB port) the indicator light comes on and I can feel it vibrating but it doesn’t show up on the desktop, finder, or disk utility. I have plugged it into a windows computer and it shows up fine, and even shows up on a different macbook so I’m not sure what the problem could be.
If the drive can be seen on others computers, you might want to connect another drive (if possible) on your computer and see if it’s recognized. You can also refer to the link below for some troubleshooting steps regarding the issue you are experiencing.
