I haven't seen any errors, so it's probably a feature rather than a bug with this drive.
I have two USB drives on my system, and one of them takes about 30 seconds to spin up. It is very annoying when I'm rebooting the system but it decides it has to spin up the unmounted drive before it can finish. I can understand the need to scan everything when it boots up, but can't imagine why it needs to scan everything on the way down.
I've seen systems need to spin up drive to umount then - to sync the fs. Even for an idle fs the kernel seems to want something, maybe formally closing a journal or something?
To test, do a sync, wait for the drive to spin down, then umount. See what happens during the umount.
