Of course!!
I *always* umount the disk before unplugging it. That didn't stop the OS
from freezing.
I've been using OpenBSD since 2.6, this never happened to me with any
other USB hard disks. This one in particular i bought it a couple of
days ago.

Hello, i'd like to inform a problem when dettaching an external 1TB
USB disk drive , the system just freezes, i can't type anything.
Also It stops responding to ping.
If i don't unplug it then i can use the disk normally, i can copy
and delete files with no problem. But as soon as i unplug the USB
cord, the machine freezes.
I've tested it on several machines, different OpenBSD versions
starting from 4.3, i'm not asking for support, i know old OpenBSD
versions are no longer supported, but this seemed pretty odd, i
suppose that plugging and unplugging a USB disk should not cause any
problems on any OS version.
These are the lines on dmesg about this disk:
