UR22mkII - sound dropout during waking up HDD from sleep

I noticed that during waking up HDD from sleep (i can hear how HDD starts running) UR22mkII has two sound dropouts (for 1 sec). I tried different buffer settings, different USB, also external power. Drivers re-installation. Nothing helped.

For me it looks like unstable USB signal during HDD load. But other USB devices working fine. What could be wrong? Thanks.
