I found a workaround. Steps for workaround: 1. Open caja or any file manager. 2. Unmount all the partitions on the drive by clicking on the eject button. 3. Open Gnome Disk Utility or run "gnome-disks" command. 4. Select the HDD. 5. Click the "Drive Options" button located on the upper right. 6. Click "power off".
The drive will not spin up again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1937350 Title: USB HDD not properly spin down after safely remove To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1937350/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
