Hi, in the manual of the box (page 14), clearly indicates that it includes an individual HDD connector, which can be considered misleading advertising and possible cause of legal claim. I have done what you tell me, but it makes a bridge between the POWER and the HDD, that is, when it reads the HDD, it blinks, but so does the POWER button, so if the HDD works, it is on, and if no, it is off, in addition to the lower front light.
I do not think that a box of about € 90 has such a simple cut.
Greetings
