USB HDD spindown problem

[dvdr]

I have been using the previous version on my Raspberry PI so far without the problem, that I am facing now - they could be related to either the new MinimServer version or the Raspbian installation, that I am using right now.
Previously, I have been using a ready to use image of soft wheezy, which had contained Minimserver 0.7x, now I downloaded the NOOB version from raspberry.org and installed Raspbian.

My Western digital 1TB USB HDD is USB-powered (without problems) and spins down/sleeps after 10 minutes of non-usage.
Whenever I was using it with 0.7x, I could come home in the evening (RPi stays on 24/7) and just fire up my UPnP control point and play some music.

Now (after installing the new MinimServer version on the new Raspbian installation), after the spin down MinimServer does not show in my control point anymore, as if MinimServer, too, has decided to stop.

Firing up MinimWatch, it tells me "could not find /media/Music/music", which is the mounted path / share, where my music resides on the USB HDD.

When I choose to restart MinimServer from MinimWatch, it instantly starts to scan the share (I can see that in the log), so it somehow the path to the USB HDD must still be there.... I am a bit confused, why that happens.

I must add, that this NOOB installation already mounted the drive properly by itself, I did not have to execute the manual steps to assign a mount point the the USB-drive from the terminal.

Can anyone jump in, how I can solve this problem? Is it Raspbian-related, or is this something, that comes with the new MinimServer version?

Thanks!
