we need to remove drive after device has correctly by remove.

With this patch:

Windows : if drive is locked/"mounted", the hot-unplug fail and disk is accessible (100% safe)

Linux: without hotplug module : the hot-unplug fail and disk is accessible (100% safe)

Linux : with hotplug module : the hot-unplug work, but no verification is done is the drive is mounted
