ejecting usb removable magnetic hard drive /dev/sda

[drmikecooke]

Been getting message from ejector in menu bar "failed to eject . . ."

sudo eject -v /dev/sda

gives

eject: device name is `/dev/sda'
eject: /dev/sda: not mounted
eject: /dev/sda: is whole-disk device
eject: /dev/sda1: mounted on /media/mike/0706b956-dc8b-4b18-8a9d-98aab0280ee5

eject: /dev/sda: trying to eject using CD-ROM eject command

eject: SCSI eject failed
eject: /dev/sda: trying to eject using floppy eject command
eject: floppy eject command failed
eject: /dev/sda: trying to eject using tape offline command

btw does ANYONE use tape any more?

The drive is 1TB Seagate M3 portable

Guess I should complete with

udisksctl power-off -b /dev/sda
